Re: 42" VIZO Television Will Not Power On
My coax tuner doesn't work on this set after replacing that voltage regulator. Anyone know of a fix. Can it be repaired? Any help that comes my way, thanks in advance.

Re: 42" VIZO Television Will Not Power On
I know that c1 would be a capacitor, hence the c in c1. I don't have a parts list for that board, however I do know that some places on the board do not have a part installed even though there is a spot prepared for one. Start a new post with your specific problem for faster and more advanced service. Good luck....

Re: Newfound hatred for windows 8
I thought about upgrading from 7 64bit to 8, and am still deciding. Microsoft IMPO just wants $. Think about the Xbox 360. Buy the console, games, and internet service to play online. Well, not the case. Now pay Microsoft every month to access the intranet. Xbox live is what they call it. Please. Do I have stupid watching over me? I and many others agree that a basic office package should be in included with any version of windows. Really!, just include it in an update.Last edited by Cubone222; 11-21-2012, 05:51 PM.

Re: vizio 42 gv421 no picture/sound
I think those green and silver spots helped someone to denote pin 1 on the chip. They were replaced, or factory screwOP. You need better focused pictures. Front and back of the power supply board if possible. The whole main board. And a good picture of the whole back side of the TV so that the regular members can see how everything hooks up. I to had a bad voltage regulator on a 42" vizio. It sounds like a main board problem. But could be ccfls. Good luck....

That appears to be for a computer monitor with bad pixels, I doubt that that would work anyway but idk, I've heard of people tapping on the plastic bezel (frame) of the tv or gently tapping on the screen where the dead pixel is, I've never tried it cause no dead pixels here. good luck.

Yo, I think I have a dead pixel. If it's not a grain of sand behind the screen do you think this will work?

Re: 42" VIZO Television Will Not Power On
I didn't get any voltage through U2 after I replaced it. U2 is the only regulator I replaced. U8 however still had the 1.24V difference. Budm says it is suppose to be 1.25V difference.I thought I screwed the board when it read 0v on all U2 pins. Discouraged, I hit the power button anyways. To my surprise slave lit up and shut back down. I had hope so I bragged to everyone here, "I got it to turn on but no back lite". They hung their heads in disappointment. But not me, I still had hope. I noticed that none...Last edited by Cubone222; 11-11-2012, 03:12 AM.

Re: 42" VIZO Television Will Not Power On
I just hooked this TV up to the computer VGA cable. After it booted I saw this red and blue haze in the bottom right corner. I thought darn man, not a LED gone crazy. I don't even know if this TV has LEDs, but that is what I thought. Turns out, it was my walpaper bleeding through windows AERO peek. Thank you Jesus. This thing sure looks better from the front although I really enjoyed working on it. I left U8 alone. U2 was a nightmare.Thanks budm, misterd, and all you other guys that left a reply. My PS3 thanks you also. Here is a picture...Last edited by Cubone222; 11-11-2012, 03:16 AM.

Re: 42" VIZO Television Will Not Power On
Yea, if only I could have misterd. It might be a cold solder but who cares. As of now the TV comes on. Amazing! It powered on. The light went from amber to white. It had a blue screen that said no signal. Is that normal?

Re: 42" VIZO Television Will Not Power On
I can't cut the three pins; I can't wick the solder. It's a nightmare!

Re: 42" VIZO Television Will Not Power On
Sorry for the wait everyone. I just got all the supplys and will post back when I am finished with this operation. BTW, that game was cool.. Soldering may be too hard for me. I can't get the solder to stick and/or flow. A real pain! Any supporters? Guess not. I will bury the hachet and try again.. I think the solder I got is lead free junk!Last edited by Cubone222; 11-10-2012, 06:40 PM.

Re: 42" VIZO Television Will Not Power On
OK budm. I will try and replace U2. I will replace U8 even though it is within tolarance. It seems to be getting bad although it is still OK. I hope that an 80W iron will be suffient. I have zero sodering skills. But youtube has got me somewhat prepaired. I will post back after I do said repair. You are very helpful. Thanks.
