VIZIO LCD Problem

[xjimtx]

I was hoping someone could help diagnose a problem I am having with my TV. It is a VIZIO VW46L FHDTV20A. At random times I get 4 evenly spaced black lines running horizontally across the screen and then half the screen vertically (always right to left) fades to black. In about a minute its back to normal, but 5 min later or up to several hours later it happens again. Really I'm mostly interested in knowing if it is something that is worth repairing or should I be looking into a new tv

Appreciate it

I have a similar issue, but mine gets a lot worse after it is warmed up.
What others suggested is to try cleaning or reseating the ribbon/flex/ cables at the top of the TV(there are four of them). Those brown clips fold down, then you can lift the flex cables out. You can try reinstalling a couple of times, maybe that is enough.
I'm at that stage, waiting on a cleaner spray that I have ordered. If it won't fix it then most likely I need a T-con board.

My thread is VW42L but I made a mistake in the title.

No I haven't, I'm afraid that's beyond the scope of things I do (if it was a computer that be a different story). I was hoping from the description I gave someone would say that they have seen/heard of the problem before and either its a simple repair and would pay to have it fixed or that I'm screwed and should start saving for a new one

Re: VIZIO LCD Problem

Your problem could be the t-con, could be some thing else. If its the t-con you could probably replace it yourself with one from ebay for around 30-80 dollars (depending on the cheapest one listed when you look). And it would take about an hour to do at most. Whether that makes you interested in replacing the tv, or trying to fix it is up to you. The tcon has 2 or 4 flexible ribbon cables which usually you pry up a long thin strip holding them in (the strip rotates sorta) and then you can remove the cables and clean them lightly and reinsert them, make sure they are perfectly straight, ligned up, in any notches that seem normal, and as deep in there as they were to begin with (as deep as they will go).
