Kells Saridjo: I need to replace m vizio main board. 3642-0312-0150 (5A). I found one on ebay. everything looks the same. only that's a 3642-0212-0150 (5A) Will it work?
Grants Pass TV Repair: Norcal715 has a couple videos where he shows people how to repair a common problem on the Vizio mainboards. and the part is 65 cents. Look him up on youtube.
mrbrain80: I had this problem, I thought it was the power supply but ended up being the main board. found the main board part locally for $50. Not really worth fixing since it could happen again..
Edison Restrepo: hello dear friend first wanted to thank him for his great contribution to these videos and who have helped me a lot. I also wanted to ask a question in reference to an HDTV PDP42 * 3200 I have. the problem is that when I turn on the tv the sound comes out fine but as I get only image in red and tried to balance the colors but gives no result .. PLEASE IF YOU CAN HELP ME AND THANK YOU FOR YOUR GREAT HELP ...
Simon Repairman: I found a seller on Amazon has repair kits capacitors, this is the cheapest I found on the net. His seller name is Procacitor He also makes custom kits, you only have to ask him
Grants Pass TV Repair: Yes you can. My shop is at 938 SW 6th street. About one block past 711
on the right. I'm generally in between 10:30 and 5:30 unless I'm doing a service home service call.
yosimar urrutia: I have the same exact TV with the exact same problem. Do you have a shop I can stop by?
Grants Pass TV Repair: Sorry but I don't have a clue.
Manuel Graciano: Hello I have a vizio 320vl and I have an issue with it. It turns on, however, on the display it shows the logo "VIZIO" but very dark n dim . What do u think it can be?
abosman1: This video was very informative video with a very good sus path. Thanks for sharing you save me time and money
Jubie Ruiz: I had the same problem and found a board for $60 on ebay and it worked like a charm. Thanks alot.
stephanie33069: help, I have this same TV, and got the "pop of death" from what i hear its called. heard a pop and the screen went blank. vizio logo still on but power wont turn off with remote or power on the tv. if i unplug it goes off and i can turn it back on by remote ot panel on tv. still no sound or pic,
Im see blogs its because of blown capacitors that are easy to replace. I see the power board but no capacitors, except maybe under the metal housings on the board. any ideas on how to fix this
Grants Pass TV Repair: I repaired this TV by replacing the main board not the inverter board. If you suspect your inverter board is bad you need to test the transformers and mosfets to see if they are shorted.
You might start by testing the micro fuses on the inverter boards and go from there.
Martino Radcliffe: hey i got the same tv 10A and I have the same problem has @trevabbie that screen went to about half brightness and a buzzing sound started in the rear of the tv. and Im looking on ebay for inverter board but i see 2 different kinds one that say slave inverter board and the other one that just only say inverter board and they look different. I want to know how I know which on is the right one before i purchase it online?
Grants Pass TV Repair: Only tips I can give you are in this video. In this case it was the main board that went bad.
gtrev99: I have a vizio VW32L HDTV20A. Im try to fix problem unit does not come on. I have a orange vizio light does not go from orange to white. I suspect the power board, I hear no click on power board when power button is pressed, also I only have 5volts DC on the output side of the board no 12v or 24v.Not sure if the control voltage for the power board comes from the main board then to the power button then to a relay on the power board to supply the missing voltage.Any input would be appreciated, l
Grants Pass TV Repair: The main board is difficult to test other than to look for missing voltages on various locations as marked on the board or schematic, but when you mention hearing a buzzing noise and a picture with only half brightness I would think your inverter board may have a problem rather than it being a main board problem.
trevabbie: I have the same model tv with a 20A at the end rather than the 10A you show on the video. Last night the screen went to about half brightness and a buzzing sound started in the rear of the tv(almost sounds like a relay chattering) I have read a few posts and all seem to lean to the main board. Any suggestions on how to check?
gubni: I've fixed a few of these now. It always seems to the the 1117 regulator on Vizio TVs but occasionally in a different spot. Check voltage on that middle pin and you will find the bad one.
Grants Pass TV Repair: Yes but in this case I replaced the whole main board. Check the micro fuses on the main board first. Sometimes they go bad.
domincan231: Were you able to find a fix? I have the same issue
mrbrain80: The fuse on the power supply/board was test and is good.
mrbrain80: Hi I have a vizio gv42l. The vizio logo does not come on. I though it could be the power supply board but the capacitor looks good. Any ideas? Thanks in advance
gubni: Yep, my board is 364700620150. Still GV47L but minor difference. My problem is I get back light but no video.
Grants Pass TV Repair: I think you must be describing a different main board for Vizio. On my Vizio TV main board part number is 364700120150 (5A) and the only part with a U33 location number next to it is a small 16 pin IC with the part number P1503257QE, but no AMC1117. mine does have 3 AMC1117 adjustable regulators but they are in completely different locations.
gubni: The label for U33 is almost under a cap, so it can be hard to find. It's about 6.5" from the left side of the board and 2" from the top. My board is 3647-0062-0150 and I had brightness but no picture. From reading other forums this is a very common problem.
Grants Pass TV Repair: I found 3 of the AMC1117 regulators on this board but nothing with the location characters of U33. Two of them were under the location characters of U5 and U18 and the third didn't have any location number on the board so I'm wondering where you found a the U33? I looked near the power in connector and couldn't find it.
gubni: The main problem with these is U33 near the power in on the motherboard. When turned on this should have 5v on the top leg and 3.3 in the middle. The main problem is the middle voltage will be close to 2v. Replace it with AMC1117. Google for a supplier or try electronica-usa
foggyrider: Thanks so much for this video. My 4 year old GV47L had the exact same symptons. I followed what you did in the video, I had good voltage at the inverters, so I ordered a main board ($180) and it fix it!
Tony Threesikkha: Thanks 1 million for your share.
hoopfan71: No such luck - I ended up having to replace the main board.
Dwayne Carey: amber light, no click??? What to do?
hoopfan71: I have a GV42L with the same symptoms - the original owner told me the main board is faulty per a tech. Hopefully I can fix it cheaply at the component level.
THEtechknight: Actually, these VIZIO boards are KNOWN for this.
Orange to white light, but nothing happens. There is a low voltage dropout regulator that fails and must be replaced. but ill be DAMNED if i can remember where it was. lol.
da9ball: I had the black screen of death and found your video to be helpful. I too tested some of the small Littelfuse (LF) micro fuses at F1 to F3 locations and found the the fuse at F3 to be faulty. Found a LF fuse on Ebay that matched the service manual's description and piggy backed it on the old fuse and it seemed to do the trick. Thanks for video though it gave me good insight on what I would be looking at when I opened it. A good tear down instruction video would be cool to compliment this one.
Nelson Chua: When all else fails.....SHOTGUN (replace the whole board) it! B^)
Maxxarcade: Very similar to the situation I have with the Philips/Magnavox set I'm working on. Found a board for about $150 on Ebay, but I'm not sure the customer will go for it.
Also bringing in an Akai LCD/DVD player combo this week, and I hope to make a video about that once I dig into it.
N0JRJ's Ham Stew: Glad to see another video from you. Its been a while. Hope everything is going well.
