VIZIO LCD TV GV47L FHDTV10A




What do you think about this video?

Tim Funk: What if you don't see the vizio light at all (stand by or on) it's it still the power supply board 

Sunlight Paladin: the Whole right side of my screen Goes really dark and distorted and i have to smack it or shake it to make it stop . 

Juan Castacan: I have the same model but I don't have any response from the on/off touch pad, I have the orange light on but no power Is getting to the touch pad and therefore I can't turn it on with the remote either. anyone can help me?

jarvis agulto: I have a blurry image and static, then it gets clear then again gets blurry/static. whats the problem and how can I fix this? please let me know

Adam Spinelli: +Grants Pass TV Repair I've got the same model, but my problem is, the screen comes on for a few seconds and then shuts off. vizio logo remains white. Once I press any of the menu buttons, they light up for about a second and then turn off, followed by the logo turning orange. Does that sound like a Mainboard issue, or a power board issue? I don't have the tools or the know how to test the boards, but i'm pretty confident I can just swap them out. I would just like to know what I should buy before I go wasting money. This would make an awesome christmas present for my little brother. Help me out and I'll buy you a beer! (if you take paypal.)

Dan Daugherty: i have the VW47L version, given to me by a friend who didn't want to take the time to have it repaired. it is very similar to the GV model you are showing in this video. He said he heard a pop and it stopped working, he did try and replace the main board but that did not help. All fuses appear good, when I plug it in, the VIZIO does turn hello, I do not hear any relays when I press the power button on the side and nothing changes. I do have the 5v standby but no other voltages coming out of the power supply. I"m not sure if I should have the 12 / 24 volts out since I don't hear the relay or if there is some type of power check on the board that if one is missing, it won't try and turn on? Yours in the video does have the 24volts going to the inverter boards but you did hear the relay. Bad power board? any thoughts?

hoopfan71: @hoopfan71 No such luck - I ended up having to replace the main board.

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.

Brian Doyle: 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: @GrantsPassTVRepairs Yep, my board is 364700620150. Still GV47L but minor difference. My problem is I get back light but no video.

Grants Pass TV Repair: @gubni 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.

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..

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.

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.

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.

Grants Pass TV Repair: @gubni 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.

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.

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: Only tips I can give you are in this video. In this case it was the main board that went bad.

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!

hoopfan71: @THEtechknight 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.

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.

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.

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

N0JRJ's Ham Stew: Glad to see another video from you. Its been a while. Hope everything is going well.

Tony Florida: Thanks 1 million for your share.

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.

Grants Pass TV Repair: Sorry but I don't have a clue.

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

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 ...

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?

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.

Dwayne Carey: amber light, no click??? What to do?

abosman1: This video was very informative video with a very good sus path. Thanks for sharing you save me time and money

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.

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

Gary Revuelto: 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

Jubie Ruiz: I had the same problem and found a board for $60 on ebay and it worked like a charm. Thanks alot.

Nelson Chua: When all else fails.....SHOTGUN (replace the whole board) it! B^)

Martino R: 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?
