1
00:00:00,080 --> 00:00:05,600
micro HDMI may very well be the worst

2
00:00:03,120 --> 00:00:10,240
mainstream connector on the market it's super compact while still carrying the

3
00:00:07,839 --> 00:00:15,679
same high quality video signals of its bigger more competent brother but it is

4
00:00:12,480 --> 00:00:16,480
the very definition of an achilles heel

5
00:00:15,679 --> 00:00:24,560
this four dollar part four dollars turned a 3

6
00:00:21,520 --> 00:00:26,240
000 camera into a paperweight and the

7
00:00:24,560 --> 00:00:31,119
cost to have it repaired by a sony authorized service center

8
00:00:28,359 --> 00:00:34,000
500 freedom dollars that

9
00:00:32,000 --> 00:00:39,520
is why today i will be taking matters into my own hands that is why right to

10
00:00:36,880 --> 00:00:43,200
repair matters and that is why i'm going to tell you about our sponsor in case i

11
00:00:41,600 --> 00:00:47,920
screw up this camera and i have to buy a new one build redux build redux makes it

12
00:00:46,160 --> 00:00:51,920
easy to configure your new build with support guides to help along the way

13
00:00:50,000 --> 00:00:56,239
they also offer competitive pricing as compared to building a pc yourself head

14
00:00:53,920 --> 00:00:59,840
to build redux dot com slash Linus and start your new build today

15
00:01:07,439 --> 00:01:12,080
let's begin with a bit more backstory when i was shooting the sponsored

16
00:01:10,560 --> 00:01:16,240
ultimate streaming setup video for elgato a little while ago i was struck

17
00:01:14,159 --> 00:01:21,920
by how much more comfortable that setup was to use compared to my one at home

18
00:01:18,799 --> 00:01:24,640
and the reason for that is that at home

19
00:01:21,920 --> 00:01:28,159
i have to crank my key lights up so bright that they're uncomfortable to

20
00:01:26,240 --> 00:01:32,799
look at in order to get a clean image out of my cheap canon camera which got

21
00:01:30,240 --> 00:01:38,159
me thinking i'm not about to downgrade to a webcam but if i want a dslr or a

22
00:01:36,479 --> 00:01:42,560
mirrorless that has outstanding low light performance so i can turn those

23
00:01:40,159 --> 00:01:47,119
lights down what are my options here's one how about the a7s2 that we already

24
00:01:45,200 --> 00:01:52,720
own here at the studio but we haven't been using because it's broken

25
00:01:49,439 --> 00:01:55,360
i mean it's not completely broken i can

26
00:01:52,720 --> 00:01:59,439
turn it on and wait were we expecting that to happen did it magically start

27
00:01:57,280 --> 00:02:02,880
working uh this is inconvenient but also i'm happy

28
00:02:00,719 --> 00:02:05,920
ah okay

29
00:02:04,159 --> 00:02:11,200
this is one of those situations where it's it's working enough that it knows it's

30
00:02:09,200 --> 00:02:16,000
supposed to be working now just to demonstrate that it's not

31
00:02:12,720 --> 00:02:20,319
the cable what is this uh s5

32
00:02:16,000 --> 00:02:23,280
oh yep there we go confirmed tv works

33
00:02:20,319 --> 00:02:25,920
cable works actually this is a this is a really important thing to bring up you

34
00:02:24,640 --> 00:02:30,560
guys might wonder why exactly the fact that the micro HDMI

35
00:02:28,239 --> 00:02:34,879
port on this camera not working is even a problem for us here in the studio and

36
00:02:32,080 --> 00:02:39,040
the answer is that while the camera does have a built-in display

37
00:02:37,200 --> 00:02:42,560
usually in a production environment you'd need a much larger one in order to

38
00:02:41,040 --> 00:02:48,480
make sure that you're maintaining focus so we'd hook up something like this external monitor from small hd that

39
00:02:46,160 --> 00:02:52,480
means that every hour this camera's in operation it's got something plugged

40
00:02:50,239 --> 00:02:55,040
into its micro HDMI port which eventually and we're talking in a matter

41
00:02:54,400 --> 00:03:01,200
of tens of hours or hundreds of hours not thousands of hours

42
00:02:58,959 --> 00:03:04,800
it is going to break 50 bucks gets you high quality solder flux and wick with

43
00:03:03,280 --> 00:03:09,840
the necessary applicators you'll spend anywhere from 25 to 100 depending on how

44
00:03:07,760 --> 00:03:12,879
baller you want to go for some kind of precision screwdriver set you'll need

45
00:03:11,440 --> 00:03:17,440
another hundred dollars in change for a soldering iron and a hot air station and

46
00:03:14,800 --> 00:03:22,400
20 bucks for a mystery 21 ounce water bottle from lttstore.com

47
00:03:19,519 --> 00:03:26,640
and even after buying all of that stuff you are still going to be out ahead of

48
00:03:24,800 --> 00:03:31,360
what you would have spent on someone else doing it for you and now you own

49
00:03:28,879 --> 00:03:35,519
all these tools which is pretty cool honestly the biggest factor for me

50
00:03:32,720 --> 00:03:39,440
though was that i have nothing to lose if i break it so what i was already

51
00:03:37,920 --> 00:03:43,840
gonna have to replace it anyway and the only thing i really had to buy was 20

52
00:03:41,680 --> 00:03:48,799
worth of micro HDMI ports so since this operation can clearly be done

53
00:03:46,879 --> 00:03:52,319
we actually found a guide on how to do it online though it

54
00:03:50,640 --> 00:03:57,519
omits the actual soldering because that's a service this person offers and

55
00:03:54,480 --> 00:03:59,280
his name isn't louis rossman

56
00:03:57,519 --> 00:04:02,799
i think we can put together the missing pieces here so this is where the

57
00:04:00,560 --> 00:04:06,640
scripted portion of this video ends and i start disassembling this camera

58
00:04:04,799 --> 00:04:10,080
wish me luck everybody got an exploded view of the camera right here and i

59
00:04:08,400 --> 00:04:13,120
talked to callanan who actually used to do a fair bit of this work at his old

60
00:04:11,439 --> 00:04:18,639
job and he says we are going to go in from the bottom and the back so that is

61
00:04:16,000 --> 00:04:18,639
where we'll start

62
00:04:20,239 --> 00:04:26,400
yeah this should be fine let's just see if it's loosened at all

63
00:04:24,880 --> 00:04:32,800
whoa hi yep look at that

64
00:04:29,840 --> 00:04:35,360
yep plate came right off wait and oh

65
00:04:36,000 --> 00:04:42,560
whoa that was exciting moment seems to be

66
00:04:40,160 --> 00:04:45,840
hampering me a little bit here i think i have to actually take the

67
00:04:44,000 --> 00:04:49,040
screen off and disconnect the ribbon on this side

68
00:04:47,280 --> 00:04:54,479
hold on i got this though i got this i'll get this all labeled in a sec

69
00:04:51,199 --> 00:04:54,479
famous last words

70
00:04:55,680 --> 00:05:02,240
yep there we go look at that is that a vapor chamber or

71
00:04:59,600 --> 00:05:04,800
is that just a copper spreader oh wow that's interesting look they're carrying

72
00:05:03,840 --> 00:05:11,520
heat way up here man i'm stressed i get really warm

73
00:05:09,360 --> 00:05:15,039
when i work on stuff like this like i don't want to break it

74
00:05:13,039 --> 00:05:17,919
and i also don't want to not get content out of it

75
00:05:16,400 --> 00:05:21,759
and i feel like if i break it it's not really a video i can't get it out past

76
00:05:20,240 --> 00:05:27,520
the sticker you might just have to force it a little there we go would you look at that

77
00:05:25,680 --> 00:05:32,560
did you just look at that wow it's actually really easy to change

78
00:05:30,160 --> 00:05:36,160
out the card slot this is as far in as you have to go and

79
00:05:34,639 --> 00:05:40,560
they've got it on its own daughter board so boom new sd card slot

80
00:05:38,720 --> 00:05:44,160
just like that because that's something i could see failing a lot too

81
00:05:42,400 --> 00:05:51,039
everything's under control also this copper shield is off now more

82
00:05:46,560 --> 00:05:54,639
cooling uh we've got made by micron

83
00:05:51,039 --> 00:05:56,400
presumably this is dram we've got sony's

84
00:05:54,639 --> 00:06:01,280
image processor uh wow this folded cable here is looks

85
00:05:59,520 --> 00:06:05,440
pretty challenging no no that's fine that's fine it's fine

86
00:06:02,960 --> 00:06:09,440
it's just a sticker calm down brandon calm down you're stressing everybody out

87
00:06:07,520 --> 00:06:15,440
chill time to start popping out the dozen or

88
00:06:12,800 --> 00:06:21,039
so ribbon cables all around this main board the good news is that the the

89
00:06:18,240 --> 00:06:24,639
cable memory should pretty much tell us where they all go back in

90
00:06:24,880 --> 00:06:27,360
look at that

91
00:06:28,400 --> 00:06:34,479
easy peasy easy

92
00:06:31,759 --> 00:06:40,240
more cooling more thermal pads oh wow so i misidentified this i think that i had

93
00:06:38,080 --> 00:06:44,880
said this looked like the main processor but i actually doubt that now and i had

94
00:06:42,639 --> 00:06:50,720
also said that maybe this was dram but i doubt that now too because

95
00:06:47,039 --> 00:06:53,199
this pin pattern looks like dram

96
00:06:50,720 --> 00:06:57,759
and it sits right under what looks like it might be

97
00:06:55,360 --> 00:07:01,120
some kind of integrated package i don't know much about the architecture of a

98
00:06:59,360 --> 00:07:05,280
camera this is all just kind of me making things up as i go so take it

99
00:07:02,800 --> 00:07:09,759
for what it is and that's it that's the culprit

100
00:07:07,280 --> 00:07:15,360
right there oh wow it's mangled

101
00:07:13,440 --> 00:07:19,199
no wonder it's broken the thing is it's not just like the

102
00:07:17,199 --> 00:07:22,319
resiliency of the pins inside you gotta understand there's a lot of strain on it

103
00:07:20,880 --> 00:07:26,240
from the weight of the cable and there's just no real getting around that

104
00:07:24,639 --> 00:07:31,520
okay it's getting real now oh god i did not

105
00:07:28,800 --> 00:07:35,039
label a thing i'm gonna write pcb question mark i'm pretty sure it is

106
00:07:33,599 --> 00:07:38,000
sanity check let's make sure we're removing the right thing here we want

107
00:07:36,880 --> 00:07:42,960
this guy cool right this feels like a lot of heat to be

108
00:07:41,039 --> 00:07:46,880
putting on this if we're having trouble getting it off we can try adding a

109
00:07:44,560 --> 00:07:49,680
little bit of flux not too much not that it'll harm

110
00:07:48,479 --> 00:07:53,599
anything but come on baby one moment please

111
00:07:53,759 --> 00:07:59,560
i'm starting to feel like this might have been a mistake go

112
00:08:00,400 --> 00:08:05,120
actually i think it's loosening i think i got it loose on the one side come on

113
00:08:03,520 --> 00:08:09,120
come on come on come on come on come on hey there we go

114
00:08:07,440 --> 00:08:16,000
oh my god now we need our soldering iron and our wick

115
00:08:14,080 --> 00:08:19,360
i named him john so we're just going to pick up all of our extra solder with

116
00:08:17,680 --> 00:08:22,400
this bad boy i've got most of the through holes

117
00:08:20,720 --> 00:08:27,840
cleared now i think it's clean

118
00:08:25,199 --> 00:08:32,240
here's the backside looks pretty good we've got five tries

119
00:08:30,319 --> 00:08:36,640
at this i have five micro HDMI connectors so here's the plan

120
00:08:34,719 --> 00:08:41,839
i'm gonna take this guy i'm gonna put it right there

121
00:08:39,440 --> 00:08:47,200
and all of those need to go exactly on all of those pads so we take this

122
00:08:44,720 --> 00:08:53,160
and we put some of the solder kind of over these contact points here and kind

123
00:08:49,279 --> 00:08:53,160
of spread it around a little bit

124
00:08:57,519 --> 00:09:03,279
that is not good let's just get rid of this again

125
00:09:00,880 --> 00:09:07,279
you can see there's a giant ball of solder uh across two pins in a couple of

126
00:09:05,760 --> 00:09:11,519
places here so i did put a little bit too much to grab the extra solder we're

127
00:09:09,920 --> 00:09:16,480
just going to take our tip which is clean and we're just going to throw some

128
00:09:13,360 --> 00:09:18,959
flux on there and we're going to try and

129
00:09:16,480 --> 00:09:25,120
kind of loosen that up and grab it so now basically what we flow it and go for

130
00:09:22,000 --> 00:09:26,720
it okay let's flux it up baby

131
00:09:25,120 --> 00:09:32,880
here we go shine for me baby

132
00:09:29,600 --> 00:09:36,240
this little light of mine

133
00:09:32,880 --> 00:09:39,360
i'm gonna let it shine

134
00:09:36,240 --> 00:09:41,120
once it's all silvery we just go for it

135
00:09:39,360 --> 00:09:46,480
oh god i blew it away oh boy

136
00:09:42,640 --> 00:09:46,480
okay so we have a slight problem

137
00:09:47,519 --> 00:09:54,320
when i put the heat

138
00:09:51,920 --> 00:09:58,480
on the micro HDMI it melts the plastic

139
00:09:56,959 --> 00:10:03,440
so basically

140
00:10:00,080 --> 00:10:05,600
i need to heat it up and then instantly

141
00:10:03,440 --> 00:10:07,839
absolutely nail the placement of this thing

142
00:10:09,519 --> 00:10:13,360
oh my god go on there hold still

143
00:10:14,959 --> 00:10:20,959
oh we were close that time it's not that it's off it's that the

144
00:10:19,519 --> 00:10:25,600
plastic melted and it looked like the back pins were

145
00:10:23,440 --> 00:10:30,800
on still but it's hard to tell okay all right i give up for today

146
00:10:29,040 --> 00:10:35,839
oh that is a that's a shame we're back ladies and

147
00:10:33,040 --> 00:10:41,680
gentlemen and we got solutions kyle from engineering said hey guys you need a hot

148
00:10:38,800 --> 00:10:44,079
plate well we don't have a hot plate and we don't have time to wait around

149
00:10:43,040 --> 00:10:50,000
for one so we've got a hot brick

150
00:10:46,279 --> 00:10:52,720
145 degrees celsius ladies and gentlemen

151
00:10:50,000 --> 00:10:56,079
we baked that brick like the boss as we are

152
00:10:54,560 --> 00:11:01,040
now it's time to take another run at this without this giant ground plane

153
00:10:59,200 --> 00:11:06,240
here sucking up all the heat that we're trying to use to desolder our shiz

154
00:11:03,839 --> 00:11:10,959
so we'll get our let's get our hot air station we're going to try and pull this

155
00:11:08,480 --> 00:11:15,839
micro HDMI that we did manage to put on last time but didn't connect fully

156
00:11:13,440 --> 00:11:20,000
and we're getting up near 100 a hundo

157
00:11:17,360 --> 00:11:20,000
here we go

158
00:11:20,720 --> 00:11:26,560
oh oh that's a hot brick yep

159
00:11:24,240 --> 00:11:30,880
there we go and did it okay it's off again

160
00:11:29,279 --> 00:11:35,920
oh is it mangled you know what i think this might have

161
00:11:33,680 --> 00:11:40,320
actually survived andy i think we can take another crack with

162
00:11:37,360 --> 00:11:44,640
this play do you believe i believe yeah so i guess uh that's a that's a

163
00:11:43,120 --> 00:11:47,040
pretty big shot to your credibility right there

164
00:11:47,600 --> 00:11:52,959
the only reason that we're not putting flux on right now by the way is that

165
00:11:50,720 --> 00:11:57,800
there's already um like an ocean of flux on this thing

166
00:12:00,160 --> 00:12:06,720
oh i can't do this left-handed i just need to be able to steady my hand

167
00:12:04,959 --> 00:12:10,560
oh god stop

168
00:12:09,040 --> 00:12:16,240
it's so sticky so i have a slight problem

169
00:12:13,200 --> 00:12:18,560
a couple of the pins have bridged

170
00:12:16,240 --> 00:12:22,320
solder on them yep this one's a fail well this is our last crack at it

171
00:12:23,600 --> 00:12:28,320
falls oh god i think this is it i think this

172
00:12:26,639 --> 00:12:31,440
is the moment i need the microscope to know if it's

173
00:12:30,399 --> 00:12:37,440
lined up it ain't aligned

174
00:12:34,399 --> 00:12:39,200
see if the goal was to have it perfectly

175
00:12:37,440 --> 00:12:45,519
in between the pads then hashtag nailed it okay i'm trying to

176
00:12:42,320 --> 00:12:47,120
pull this off as cleanly as i can here

177
00:12:45,519 --> 00:12:53,839
because if i bend these pins we're not going to be able to

178
00:12:49,440 --> 00:12:53,839
put it back on i think i got it

179
00:12:55,360 --> 00:13:00,240
should i go for gold and try the last connector

180
00:12:58,959 --> 00:13:05,120
because i think part of the problem is that this one's got some gunk on it it's

181
00:13:02,720 --> 00:13:07,839
making it hard to get it in place it is lined up

182
00:13:08,800 --> 00:13:16,240
i'm gonna go check under the microscope i got the sign off from kyle he says

183
00:13:13,360 --> 00:13:19,519
that it doesn't appear as though what

184
00:13:17,040 --> 00:13:24,240
is going on here how did this happen one of these ribbons

185
00:13:22,079 --> 00:13:28,079
is busted shoot

186
00:13:26,079 --> 00:13:33,680
that is not repairable um unfortunately

187
00:13:30,720 --> 00:13:37,920
now the question becomes do i need that where does it go i was hoping to put it

188
00:13:36,000 --> 00:13:42,720
together just a little to see if it fires back up

189
00:13:41,360 --> 00:13:47,120
and if we can test it before we completely close it up

190
00:13:44,560 --> 00:13:50,720
oh i'm so upset right now i actually cannot tell

191
00:13:48,480 --> 00:13:55,040
where this plugs into right now so why don't we just

192
00:13:52,639 --> 00:13:59,040
leave it for the time being see what happens

193
00:13:56,959 --> 00:14:01,680
wow this is an absolute nightmare to install

194
00:14:00,240 --> 00:14:06,399
i don't know how they build these things at the factory the issue is just that there's no way to

195
00:14:04,639 --> 00:14:13,120
get my fingers in there and apply any force to it whatsoever it's just

196
00:14:08,959 --> 00:14:15,120
i'm just relying on the stiffness of the

197
00:14:13,120 --> 00:14:19,920
ribbon to go to push it in but it's not enough oh my god go

198
00:14:20,079 --> 00:14:26,399
get the f in there i don't understand this

199
00:14:24,320 --> 00:14:28,839
god my level of pissed off is so high right now

200
00:14:27,360 --> 00:14:33,680
so if i'm lucky the functions that are not

201
00:14:30,959 --> 00:14:38,079
connected will be ones that i don't need i would have to get

202
00:14:35,040 --> 00:14:40,959
extremely lucky for that though

203
00:14:38,079 --> 00:14:44,639
like we're talking horseshoes up my ass lucky

204
00:14:42,240 --> 00:14:47,760
i say if we get a signal from the HDMI port we

205
00:14:46,000 --> 00:14:52,240
we end the video there even though the camera itself is not

206
00:14:49,920 --> 00:14:56,560
fixed because that was the goal definitely makes me feel better about

207
00:14:53,839 --> 00:15:01,600
how much cameras cost i did plug in what remains of the ribbons so ow

208
00:14:59,279 --> 00:15:05,760
it's entirely possible that it is still plugged in okay so no sd card reader but

209
00:15:04,240 --> 00:15:10,279
everything else should fundamentally be connected

210
00:15:13,600 --> 00:15:20,320
no life no smoke no sparks but no life so i need

211
00:15:18,000 --> 00:15:24,320
a new top housing among other things okay well we have to

212
00:15:22,800 --> 00:15:29,760
call it here for now we'll have to resume once we get some replacement

213
00:15:27,279 --> 00:15:35,480
parts ordered we're gonna do this

214
00:15:31,440 --> 00:15:35,480
i'm gonna hate every moment

215
00:15:49,839 --> 00:15:55,759
oh thank god oh i have to pull the whole thing out

216
00:15:54,959 --> 00:16:02,240
yeah that's what i thought why do you need to pull that out though

217
00:15:59,680 --> 00:16:06,960
because it's connected to the main one no

218
00:16:03,759 --> 00:16:08,560
i have to take it apart even more

219
00:16:08,560 --> 00:16:15,360
hey there we go okay so i think if we stop at this point

220
00:16:13,519 --> 00:16:18,800
like filming i can figure out the soldering off

221
00:16:17,759 --> 00:16:23,920
camera because honestly

222
00:16:21,360 --> 00:16:31,720
that's gonna be long and boring a few moments later

223
00:16:27,519 --> 00:16:31,720
all right time to put this back together

224
00:16:42,240 --> 00:16:47,040
all right before i fully close this out yeah

225
00:16:47,360 --> 00:16:57,180
we usually would get a oh yeah it works

226
00:16:53,120 --> 00:17:29,380
everything flickered which is good

227
00:17:30,799 --> 00:17:39,120
it is now some time later and the saga is finally over

228
00:17:36,799 --> 00:17:44,559
as it turns out the original board the one that i fixed actually does work it

229
00:17:42,400 --> 00:17:48,000
just powers off intermittently which might be due to damage from the heat of

230
00:17:46,480 --> 00:17:52,400
the soldering iron we learned a valuable lesson about preheating your entire

231
00:17:49,679 --> 00:17:56,799
board before going at it which is great but unfortunately it did cost us a new

232
00:17:54,640 --> 00:18:00,799
board which was just under 400 us dollars

233
00:17:57,760 --> 00:18:02,880
that was installed courtesy of this guy

234
00:18:00,799 --> 00:18:07,840
thanks and we were getting this really weird awful green output so initially we

235
00:18:05,600 --> 00:18:12,799
thought okay maybe we screwed up a cable or something like that but as it turns

236
00:18:09,679 --> 00:18:15,440
out the potential need for sony software

237
00:18:12,799 --> 00:18:19,760
or calibration was a very real need so we ended up needing to send it to a sony

238
00:18:16,960 --> 00:18:24,240
service center pay about 200 to get our sensor calibrated for this particular

239
00:18:22,559 --> 00:18:28,559
border rather the board calibrated for this particular sensor and now it works

240
00:18:27,200 --> 00:18:32,320
absolutely perfectly in fact you already saw me

241
00:18:31,120 --> 00:18:37,039
