Re: Vizio SV420XVT Distorted Picture Issue

Re: Vizio SV420XVT Distorted Picture Issue
Its just so frustrating that it was working perfectly fine. Didnt change anything and now its not working.
Doesnt seem like it anything related to power, both boards i have power on. New board doesnt show a picture, only backlight comes on, nothing else. Cant use the power button to turn off either. Have to unplug it.
Old board allows TV to be turned on, shows that messed up picture though.Leave a comment:

Alright, yeah when i removed the old board to install the new one. I just set the old one aside and then switched them back. Any idea if static discharge is an issue, is fixable?Leave a comment:

Re: Vizio SV420XVT Distorted Picture Issue
I have nothing like those pictures.
Heres a few screenshots of the picture and the boards. There used to be a piece of tape from the yellow power supply to the cover over the main board. That wouldnt cause that image issue, right?
Thanks again for your replies so far....Leave a comment:

Vizio SV420XVT Distorted Picture Issue
Hey guys,
I got this TV from a friends parents who thought it was broken. When i got it home, i did a channel search and all was well. Well when i unhooked the coax from RF Input, the connector broke off and was on the end of the cable...no longer attached to the TV.
So i got a new main board for this and installed it all. Exact same serial, and product code as the old one. Turn the TV on and nothing at all, no backlight, no sound, no vizio logo light up...nothing.
So i have put the old board back in and im going to return the new one. Well now when... -

Hello everyone, i am Justin.
I consider myself a computer person and was given a free TV from a friends parents who thought it was broke. I have fixed it partially and here looking for some assistance.
Hope to have some good conversations with some of you, but im a newbie when it comes to TV and whatnot...so dumb it down a little. hahaLeave a comment:
