WEBVTT 00:00:00.120 --> 00:00:07.160 when one of my gaming systems spectacularly failed dumping water down 00:00:04.640 --> 00:00:11.960 the entire rest of the rack the most expensive piece of equipment I lost was 00:00:09.880 --> 00:00:15.840 this battery backup now the obvious thing to do when 00:00:14.519 --> 00:00:20.840 a piece of uh high voltage electrical equipment 00:00:18.359 --> 00:00:27.679 gets doused in water would be to buy a new one but I have a better plan you see 00:00:23.560 --> 00:00:31.360 battery backups are expensive and one of 00:00:27.679 --> 00:00:33.840 the most important parts the lead acid 00:00:31.360 --> 00:00:38.559 batteries seem to be working just fine no that isn't how I checked them to eBay 00:00:36.320 --> 00:00:43.600 I went and while I could have bought a lightly used unit Sands battery it was 00:00:41.520 --> 00:00:49.000 this shipping damaged one that caught my eye hey tyan have a look at what we're 00:00:45.960 --> 00:00:51.840 going to be working on today oh boy 00:00:49.000 --> 00:00:58.120 specifically it is thousands of dollars worth of shipping damage I got this unit 00:00:54.480 --> 00:01:00.640 for just 500 bucks meaning that it could 00:00:58.120 --> 00:01:05.880 very well be worth the time assuming not to mention dangerous process of 00:01:03.079 --> 00:01:11.479 transplanting the hopefully working internals from the shipping damaged unit 00:01:08.439 --> 00:01:14.560 into the uh well probably still good 00:01:11.479 --> 00:01:17.040 steel chassis of the original one so we 00:01:14.560 --> 00:01:21.520 can hope that's why I brought tinan he's going to help make sure that I don't die 00:01:18.600 --> 00:01:25.720 today are you out your ug whip well I am excuse me what are you doing now you can 00:01:23.320 --> 00:01:30.439 enter the rich takes to win a Hennessy Vasa rer 600 a go play disp a truck of 00:01:29.200 --> 00:01:35.000 $100,000 cash don't smash the car smash the link 00:01:33.280 --> 00:01:39.640 in the description from my point of view there's two options we can look at the 00:01:37.040 --> 00:01:44.479 original unit and try and diagnose what exactly in it may or may not be dead or 00:01:42.520 --> 00:01:50.079 we can look at the new unit which I have about 12 days to inform the seller if it 00:01:47.159 --> 00:01:53.360 doesn't work and we can determine if we think there's even a chance that 00:01:51.840 --> 00:01:56.799 transplanting those parts in here is going to make this fully functional 00:01:55.119 --> 00:02:00.799 let's open up the shipping damaged one if only there was some way to remove 00:01:58.799 --> 00:02:05.320 these fasteners like a screwdriver from LTT 00:02:02.920 --> 00:02:09.640 store.com now I have to confess to you I did something bad I did open up the 00:02:08.080 --> 00:02:14.519 original one to have a look at it I didn't touch anything which is very 00:02:12.040 --> 00:02:20.000 important because more than anything else we've ever done folks do not try 00:02:17.200 --> 00:02:23.280 this at home this is high voltage High current electrical equipment there are 00:02:21.640 --> 00:02:28.720 capacitors in here that if you touch them you will die and the batteries that 00:02:26.239 --> 00:02:31.560 too oh yeah I I fooled around with the batteries too that's why I'm pretty sure 00:02:30.480 --> 00:02:35.640 that they're working but if you wanted to validate that for me then uh that 00:02:33.480 --> 00:02:39.000 would probably be really good U Titan's background is what are you like 00:02:37.400 --> 00:02:45.239 megatronics like mechatronics engineering yeah yeah so some mechanical 00:02:41.120 --> 00:02:47.400 some Electronics oh grief yeah lead acid 00:02:45.239 --> 00:02:52.360 batteries he told me when he came in today that he was worried we might be 00:02:48.879 --> 00:02:54.080 doing the lithium ion one I was like no 00:02:52.360 --> 00:03:01.000 I know much better than to fool around with any lithium ion battery this 196 00:02:58.760 --> 00:03:07.480 volts it's pretty pretty clear that some of these boards did get a little bit 00:03:04.080 --> 00:03:10.280 rough housed in shipping like this one 00:03:07.480 --> 00:03:15.200 yeah that looks very distra I've seen so much worse than this the outside is 00:03:13.159 --> 00:03:22.599 really bad you can tell this thing took some bangs yeah but like most of it 00:03:18.959 --> 00:03:25.400 looks fine what's safe to touch like 00:03:22.599 --> 00:03:30.120 these wires for sure yeah this shroud probably maybe depending what's under it 00:03:27.239 --> 00:03:34.080 everything's probably safe but double check boards designed like this should 00:03:32.000 --> 00:03:39.680 have bleed resistors on any of the big capacitors so they should discharge in a 00:03:37.000 --> 00:03:45.239 safe time but you don't want to assume that right how do we check looks like 00:03:42.760 --> 00:03:49.239 there's a whole bunch of touch points on a lot of the main traces that should be 00:03:47.400 --> 00:03:52.680 able to be measured before you get to probating those should we change gears 00:03:51.120 --> 00:03:56.760 and have a look at the water damaged one to see if there's any clues as to what 00:03:54.879 --> 00:04:01.239 we may or may not need to salvage for sure this could be good because what's 00:03:58.920 --> 00:04:06.120 missing from the ship damaged one is all of the boards associated with the 00:04:02.879 --> 00:04:09.000 interface and the display which I mean 00:04:06.120 --> 00:04:15.479 clearly didn't get at least much water on it does anything jump out at you 00:04:11.640 --> 00:04:17.919 immediately here it's really 00:04:15.479 --> 00:04:21.840 dusty we moved all the equipment in while the house was kind of still a 00:04:19.199 --> 00:04:26.000 construction zone that's on me I think I noticed something the new 00:04:24.759 --> 00:04:32.560 one is rev03 and the original one is Rev 00p 00:04:30.440 --> 00:04:35.759 see even when you revise a product that doesn't mean that you revise every 00:04:34.199 --> 00:04:38.680 component of the product they may be completely intercompatibility 00:04:59.800 --> 00:05:06.800 go wholesale complete change out and then hope for the best depends on how 00:05:04.880 --> 00:05:10.080 much time we have probably first thing is figuring out if there's anything 00:05:08.320 --> 00:05:13.400 obvious that's not connected that's supposed to be everything should be 00:05:11.600 --> 00:05:17.919 connected I haven't actually touched anything in here because I knew that I 00:05:14.759 --> 00:05:21.639 was out of my depth yeah I more meant 00:05:17.919 --> 00:05:24.319 like shorts or disconnects oh sure other 00:05:21.639 --> 00:05:28.319 possible spots are over the fan here in fact you can see where the water drips 00:05:25.960 --> 00:05:34.919 were coming through here there are no holes convent over this board which is 00:05:31.319 --> 00:05:37.479 good these holes are obviously the relay 00:05:34.919 --> 00:05:42.160 right there breaker and then there were also holes here what's this that's a 00:05:39.520 --> 00:05:46.840 plug that oh that should not be a problem okay and then these holes were 00:05:45.000 --> 00:05:51.000 over the battery compartment which survived and is now completely dry this 00:05:49.240 --> 00:05:55.120 happened over a month ago now and it seems fine I don't think the breakers 00:05:53.039 --> 00:05:59.280 are damaged to the point where it would matter oh really cuz either they're 00:05:57.039 --> 00:06:04.520 connected or they're not connected and they're connected Ed oh 00:06:02.240 --> 00:06:10.000 balls it's probably not going to be an easy fix there's a chance that there's 00:06:08.280 --> 00:06:15.440 like some of the fuses for the inputs blue or okay maybe some of the control 00:06:13.520 --> 00:06:22.639 board or what looks like a control board back here fried uhhuh oh oh oh oh oh 00:06:21.080 --> 00:06:27.840 could this be as simple as a safety feature working for safety and our fuse 00:06:25.520 --> 00:06:32.840 blue quite possibly hey blown 00:06:30.240 --> 00:06:37.160 fuses we know this because we're getting a continuity beep on the shipping damage 00:06:35.240 --> 00:06:42.479 unit and we are not getting a continuity beep on these units this is input from 00:06:39.599 --> 00:06:48.560 the batteries to the inverter mhm this looks like it might be the ground return 00:06:46.319 --> 00:06:53.759 maybe no what is that for what I'm gathering is you don't want to just put 00:06:51.039 --> 00:06:57.879 the new fuses in because then we don't have backup fuses if they blow depends 00:06:56.440 --> 00:07:01.759 on how dangerous you want to live cuz yeah we have one attempt at these fuses 00:06:59.639 --> 00:07:07.160 not blowing again right we should probably take these out of the chassis 00:07:04.000 --> 00:07:09.080 okay I can do that cool I'll do that one 00:07:07.160 --> 00:07:13.800 one of the things I am concerned about for this is the second board underneath 00:07:12.120 --> 00:07:18.280 which may have been water damaged more than we can see here and this other fuse 00:07:16.639 --> 00:07:21.479 looks like it goes straight down whenever you're looking at an electrical 00:07:19.639 --> 00:07:25.400 system like this for capacitors you want to look for anything that's 50 volts 00:07:23.280 --> 00:07:31.520 rated or higher I would recommend checking everything but those are the 00:07:26.960 --> 00:07:35.039 ones you really want to look for 00:07:31.520 --> 00:07:38.400 275 so we want to check the big oh I 00:07:35.039 --> 00:07:40.240 didn't even see that one big and then 00:07:38.400 --> 00:07:44.280 you want to see look for the two sides of the capacitor in this case there's a 00:07:42.199 --> 00:07:49.919 whole bunch of vas around on these traces so you can just find traces on 00:07:47.360 --> 00:07:54.560 both sides prep across it and you just want to see that it's zero or close to 00:07:52.400 --> 00:08:00.319 zero now I noticed you have this set to volts DC but this says it's rated for 00:07:56.960 --> 00:08:02.440 275 volts ac yeah capacitors are rated 00:08:00.319 --> 00:08:06.240 differently for AC versus DC depending on the type but when you're trying to 00:08:04.440 --> 00:08:12.720 make sure something's deenergized you want to measure DC cuz AC can't exist 00:08:09.720 --> 00:08:15.319 when it's unplugged I'm excited they 00:08:12.720 --> 00:08:20.319 never let me play with stuff like this that's why I'm here my only thing is 00:08:17.280 --> 00:08:22.599 that if I ever die on camera I expect 00:08:20.319 --> 00:08:26.039 the company to monetize it get that cheddar I know it doesn't matter cuz 00:08:24.199 --> 00:08:30.159 they design around it but it always sketches me out when you screw a metal 00:08:28.000 --> 00:08:35.159 screw with a metal washer directly onto a PCB I just don't like it well that's 00:08:33.800 --> 00:08:40.479 probably a good thing they can cause fires sometimes while I was doing some 00:08:37.919 --> 00:08:46.279 research for this shoot I found a nice eaten handbook that I found 00:08:42.800 --> 00:08:48.160 extraordinarily entertaining oh super 00:08:46.279 --> 00:08:53.680 professional oh my God that's Professor Watson I love him the particular page 00:08:50.440 --> 00:08:57.920 that really got me was this 00:08:53.680 --> 00:09:00.839 one nine ways beer and UPS's are 00:08:57.920 --> 00:09:03.880 alike okay here she comes oh perfect I can look at 00:09:02.440 --> 00:09:10.560 that now okay I'm not going to break anything 00:09:05.920 --> 00:09:12.040 wo nice solder jaw eaten that's quality 00:09:10.560 --> 00:09:16.640 didn't realize these were passs for the ball yeah it took me a minute to figure 00:09:13.720 --> 00:09:21.920 that out too they go into what look like gigantic chunky ground it's it's they're 00:09:19.600 --> 00:09:25.200 essentially bus bars between the boards so that's how they're getting lots of 00:09:23.079 --> 00:09:29.640 power in between the two boards without having turn wires it's kind of funky 00:09:27.680 --> 00:09:34.040 though that they just use Giant standoffs I mean Metal's metal yeah and 00:09:31.920 --> 00:09:39.480 if it's metal then it's metal but like and they're brass look at this Sho we 00:09:36.920 --> 00:09:45.079 thought the top was bad yeah look giant capacitor Bank wa wa look at the size of 00:09:42.800 --> 00:09:50.000 the bleed resistors yeah yeah before we tear them both 00:09:47.760 --> 00:09:54.519 completely apart what are the odds that the short in the breaker would have 00:09:52.079 --> 00:10:00.440 caused those fuses to blow it would have had to have been a short between the 00:09:57.760 --> 00:10:05.360 breakers cuz one breaker is a single phase of power so it have to short 00:10:02.920 --> 00:10:09.480 across two phases for those to blow and in theory these should break if anything 00:10:07.760 --> 00:10:13.160 Downstream of them fails but if that were true then why would you need fuses 00:10:11.399 --> 00:10:16.440 anyway uh because you're dealing with enough power that if something goes 00:10:14.440 --> 00:10:20.880 wrong your board's going to melt right your hands are small right oh yeah cool 00:10:19.120 --> 00:10:26.519 that's my superpower I will need your small hands to get that exact connector 00:10:23.079 --> 00:10:30.160 out uh all right cool I think it's dead 00:10:26.519 --> 00:10:32.880 I it looks like it's dead I call dead 00:10:30.160 --> 00:10:40.120 oh yes okay we found another dead fuse this time on the bottom board huh all 00:10:36.120 --> 00:10:42.399 the fuse is blue the system works oh 00:10:40.120 --> 00:10:49.639 yeah okay actually getting a close-up of the two fuses is probably interesting 00:10:44.600 --> 00:10:52.920 cuz here's the noted one oh yeah oh 00:10:49.639 --> 00:10:55.760 there's your problem hey we found it we 00:10:52.920 --> 00:11:02.200 were looking at the top yeah that's not good okay that's very not good okay well 00:10:59.600 --> 00:11:06.760 no that's great now I know why it's dead yeah can actually see where some of the 00:11:04.680 --> 00:11:13.079 electricity was breaking through the solder mask around the edge of the trace 00:11:09.440 --> 00:11:15.920 oh cool that would have uh electrolyzed 00:11:13.079 --> 00:11:19.560 the water so this fuse probably tried to save everything else but it was 00:11:17.920 --> 00:11:24.279 completely soaked in water and never stood a chance 00:11:21.240 --> 00:11:26.920 unfortunately thank you for your 00:11:24.279 --> 00:11:32.240 service I found some more hidden and sneaky shipping damage on one of the 00:11:28.519 --> 00:11:34.720 boards that got a little bit crunched oh 00:11:32.240 --> 00:11:38.959 it doesn't look like it's damaged it'll impact anything but I'll be taking a 00:11:37.079 --> 00:11:43.959 closer look at this board after we get it out okay I have bad news I believe 00:11:42.160 --> 00:11:50.120 this is a different revision than the one that's in here so we may need this 00:11:46.079 --> 00:11:52.800 board to work yeah like your IC is 00:11:50.120 --> 00:11:56.760 completely yeah different from mine there's the 00:11:53.760 --> 00:11:58.480 crunch oh that might be fine yeah like 00:11:56.760 --> 00:12:02.480 it's it's it's probably fine that might just be a ground or something right I'm 00:12:00.639 --> 00:12:06.839 not taking everything out of here because we decided that we were going to 00:12:04.320 --> 00:12:11.440 keep the receptacles and also uh the side is super mangled on this one yeah 00:12:09.000 --> 00:12:15.800 for the input so I guess we just leave all of that which is kind of convenient 00:12:13.440 --> 00:12:20.320 because it means we're not actually rewiring that much so is this it yeah I 00:12:18.800 --> 00:12:25.440 think we just put it back together okay good luck everybody now under normal 00:12:22.839 --> 00:12:29.720 circumstances I would absolutely look at something like this and I'd go oh man 00:12:27.000 --> 00:12:34.639 let's just let's do a quick test of it you know on the bench but we can't we 00:12:32.800 --> 00:12:38.440 don't even have a way of connecting the top board to the bottom board without 00:12:36.240 --> 00:12:43.519 screwing the whole thing together anyway also from a safety standpoint this 00:12:40.760 --> 00:12:47.760 chassis protects us from even if we're careful accidentally touching something 00:12:45.199 --> 00:12:52.600 that we really don't want to touch yeah there were I think 7 or 600 volt caps 00:12:50.639 --> 00:12:57.720 under here looks like I'm now ready for Board 00:12:54.959 --> 00:13:01.560 number the two no way yeah I've got my Breakers almost in dude ni this is going 00:12:59.959 --> 00:13:06.839 so fast yeah we're going to plug this whole thing back together it's going to turn right on we're going to be like 00:13:04.120 --> 00:13:10.600 damn we're really good at this and it was totally worth it you know we've 00:13:08.880 --> 00:13:16.600 actually got a couple of videos coming soon on the economics of you know buying 00:13:14.720 --> 00:13:20.839 broken stuff on eBay and fixing them we bought half a dozen CPUs and then I 00:13:19.160 --> 00:13:26.600 think we bought a bunch of motherboards then we're going to compare to the median us wage and see if we could make 00:13:24.680 --> 00:13:31.399 a living just like buying things on eBay and fixing them um this one was unint 00:13:29.399 --> 00:13:35.480 this was more just I really really really really really didn't want to buy 00:13:32.959 --> 00:13:38.959 another one I don't know exactly why these are directional but I do see what 00:13:37.199 --> 00:13:43.720 looks like a diode marker on them which implies it's designed to go in a 00:13:41.079 --> 00:13:47.800 particular direction oh generally with these when they break they're high 00:13:46.079 --> 00:13:53.639 enough voltage that it'll maintain an arc even if the conductor has broken so 00:13:50.399 --> 00:13:56.440 they're filled with glass or sand that 00:13:53.639 --> 00:14:01.839 act to damp out the arc that's created okay here's your orientation cool got to 00:13:59.639 --> 00:14:05.839 say I kind of feel like I'm waiting for the other shoe to drop a little bit here 00:14:03.279 --> 00:14:09.800 on this project uh same it's going too good okay this cable was almost 00:14:08.600 --> 00:14:18.480 certainly supposed to be routed underneath but um it makes it which 00:14:15.959 --> 00:14:25.639 means that's the last screw what's your confidence level honestly pretty high 00:14:21.440 --> 00:14:27.120 now I have an idea okay I was thinking 00:14:25.639 --> 00:14:34.800 we power it up with just the battery before actually plugging it into the wall sure okay do you need help no you 00:14:32.720 --> 00:14:39.800 sure I'm used to having to carry around something heavy like this you know with 00:14:36.440 --> 00:14:39.800 your tiny hands yeah yeah 00:14:40.600 --> 00:14:49.120 yeah squeaky noises in electronics 00:14:45.199 --> 00:14:51.759 yay uh BP volt out of range UPS shutting 00:14:49.120 --> 00:14:58.000 off battery pack let battery pack the J of range which is probably too low okay 00:14:55.680 --> 00:15:03.560 oh it's probably shutting itself off cuz because it's too low too low yeah which 00:15:00.440 --> 00:15:07.920 so with a wall plug it's probably 00:15:03.560 --> 00:15:07.920 fine let's get the cover on 00:15:08.000 --> 00:15:11.920 yeah so all I got to do 00:15:11.959 --> 00:15:19.600 is slide her in I was about to say that's the last thing that's broken I 00:15:16.440 --> 00:15:21.639 forgot my son's gaming rig is like she's 00:15:19.600 --> 00:15:30.959 working but she's limping he nothing beeped or was 00:15:26.120 --> 00:15:30.959 disastrous here goes the plot 00:15:33.199 --> 00:15:38.319 I hear the UPS let's go have a look load 00:15:36.399 --> 00:15:43.560 knot powered emergency off says battery pack 00:15:41.839 --> 00:15:48.360 voltage out of range but we measured the voltage at about 200 and on the top of 00:15:46.440 --> 00:15:57.920 the unit it says nominal pack voltage is 180 volts so that should be fine yeah 00:15:54.240 --> 00:16:01.600 dude tyan oh did we do a dumb uh well we 00:15:57.920 --> 00:16:04.680 didn't oh no but I might have see that 00:16:01.600 --> 00:16:07.639 little green RPO thing it's supposed to 00:16:04.680 --> 00:16:10.680 be jumed oh yeah it is I know the thing I've meant to put that back in yep 00:16:09.560 --> 00:16:15.319 that's important after painstakingly paying 00:16:13.680 --> 00:16:19.920 super careful attention to everything we did internally I think we just were like 00:16:18.199 --> 00:16:23.160 oh we put it back together let's go test it and I think we might have just missed 00:16:21.360 --> 00:16:26.880 that jumper and that might be it well powered on already okay hold on it's 00:16:25.079 --> 00:16:32.880 saying please wait right now it worked online mode boom we're in oh that was 00:16:29.519 --> 00:16:36.480 terrible that sucks yeah let's go she's 00:16:32.880 --> 00:16:39.199 on load protected online mode okay okay 00:16:36.480 --> 00:16:46.680 yeah yeah yeah I'm plugging the pdu in okay go for it oh it's 00:16:42.959 --> 00:16:48.480 alive it's drawing the power yeah this 00:16:46.680 --> 00:16:54.160 right here this is the face of a guy who just saved thousands of dollars ah 00:16:52.360 --> 00:16:58.639 freaking awesome time to get everything plugged back in probably the worst thing 00:16:56.560 --> 00:17:03.360 that I've been doing lately no no it's not in this is the fact that the 240 00:17:01.480 --> 00:17:09.319 volt device on the other end which is the 115in TV cuz it's China I just 00:17:07.360 --> 00:17:12.640 plugged it into a 120 volt outlet and I was like I don't know maybe it's going 00:17:10.520 --> 00:17:16.039 to be fine my understanding is it does put additional strain on the power 00:17:13.959 --> 00:17:19.360 supply but shouldn't kill it immediately so I'm going to be powering my TV 00:17:18.000 --> 00:17:26.000 properly now properly well properly is you know 00:17:23.360 --> 00:17:30.240 you can just re terminate the plug onto the actual cable instead of Jerry 00:17:27.959 --> 00:17:33.640 rigging the cable to another cable right um yeah but this was convenient because 00:17:32.440 --> 00:17:37.240 I think the cable was already in the wall or something I don't know yeah you 00:17:35.840 --> 00:17:43.280 you can terminated to the cable that was in the wall yeah I don't know there was a reason I did it that way I can't 00:17:40.039 --> 00:17:48.960 remember what it was okay boop boop boop 00:17:43.280 --> 00:17:52.760 boop boop and boob 1 and 1 12,000 Watts 00:17:48.960 --> 00:17:54.480 no
