Repair Vizio TV NOT showing picture M65-C1

It is pleasure to watch your workmanship Nick

[@NicksTVRepair]

Thank you very much! I appreciate your kind words

If you want the repair to last, cut open a section of the rear cover right in the middle of that heat sink and mount a low speed computer fan directed to exhaust. Of course, a repair place can't do this because it affects the U.L. rating, but any end user should do this. Back in the LG plasma days, I would add two 12V internal fans run from a 9V regulator to both sustain boards because they hot enough to fry eggs even when everything was working properly. A small amount of air movement dropped the temp by 20C on those old LGs.

Yes my goodness, those sets would get so hot, you could actually burn yourself pretty bad on the heatsinks. I remember doing lots of repairs 5-7 years ago on the LG 60PZ950 Z-sustain and those would really heat up. I remember some people calling that TV their space heater. Smart for the fans though. We actually did this on a few LG 4k sets that had lots of problems with one of the processors burning out. We would fix at least 1 per day (mailed it from out of state for mainboard repair), but it was too complicated for people to install themselves when we sent their repaired board back with the fan already pre-soldered on the board. Since we didn't have enough volume come through locally we never did pursue it further.

Yep,especially first gen plasmas,eliminated the need for heating the living room.The power companies also made good money from plasma owners...

@@dimitrismaster On the plus side, watching the yearly Christmas "yule log" on a plasma TV gave you the ambiance *and* the heat...

Steve jobs repairs TVs , nice job dude

[@NicksTVRepair]

haha thank you! Very high compliment

Great video

[@NicksTVRepair]

Thank you for still watching my content :)

Nick Hi my name is Nicholas What amount of heat temperature do you need to reflow the Chips?

[@NicksTVRepair]

Depends on your machine, how you use your machine, your environment, the board you are working with, the solder used on that board. I won't ever tell anyone what heat profiles we use because they will always be wrong for you. The best thing to do is practice, always have a few junk boards to practice on, fine tune your profile, and once you get consistent results, then go for the actual repair.

[@fichambawelby2632]

As Nick says, it depends on many factors. But just as an idea, use around 320°C. Anyway, I’ll prefer to do a full reballing instead of reflow. Reflow is prone to fail again (I know reflow is cheaper and faster, but doing a reballing you change from non-Pb balls to Pb ones).

hello Why didn't you doubt Power?

hello did you ribald

[@NicksTVRepair]

not in this video

[@fu1r4]

It was 25.000 devices in the last video ... 😆

[@NicksTVRepair]

:) haha yes it used to be. I decided that I will be increasing that number every 1,000 units we fix. At first I wasn't going to change it until we hit 30k but then I thought that was to much of a jump so for every 1,000 units we fix I will increase it in the videos. Only problem with the recent switch is that I filmed a few videos a couple weeks ago that I haven't finished editing and am not yet sure if I will even release but if I do it was before the switch and those still say 25k and might come out after some of the newer ones that I said 26k so there might be a little flip floping going on.

[@LedYesRameshruge]

Dear This is only heating cpu and pasting the heat sinks nothing else, no testing and replacing any components

[@ohger1]

Because that's all this board needed - it's a well known issue. This Vizio board has two BGA processors that run very hot and have insufficient heat sink area to mitigate the heat build up causing the solder to crack over time. I've done hundreds of these - all the same problem.

[@NicksTVRepair]

Thank you @hoger1 for explaining further. Indeed a reflow is all that is needed since the components are all in good condition. When you do 500 of these repairs you start picking up on a few patterns and you know what needs to be done and what can be left alone. @ledyesrameshruge, I know my skills of explaining why we do certain things is lacking and I am trying to get better at that. I am trying to provide more clear information but sometimes get wrapped up in the video and forget to provide key information. With that said, please rewatch the video, because we did not heat up the CPU, we reflowed it along with the other processor and we actually hit the solders melting point unlike many other videos shown on YT where they don't hit the solders melting point and don't actually reflow the board.
