Vizio VO42L - Red Fuzz

[mchamb]

Hi everyone,
I have a Vizio VO42L FHDTV10A with a problem that I can only describe as intermittent at best, and what happens is, the dark areas of the screen start turning red and fuzzy. I havent been able to find a whole lot of information on this through typical google searches, nor here. Im capable of testing anything that needs be tested, and probably replacing as well, I just need a starting point of what someone might think the problem is, and what i can test to verify. Attached are some pictures of the problem.

Did you try reseating the cable on the T-CON board?
Need to see the pictures of the T-CON board, I would say T-CON board problem.

I hadnt yet no, but, I will most certainly crack it open and do it now! I believe from checking out the links in your signature that this is what you are referring to, correct?

That is the T-CON board but there are more than one version of this TV model, your TV may not use LG LCD panel or LG panel but different version, so you need to verify.

If you need a better Picture of a certain area, i can do that, i wasnt really sure what i was looking for, other than that nothing looked visibly fried or otherwise damaged...

OK, this T-CON does not use the typical GAMMA IC AS15/AS19 IC.
So did you try re-seating the cable between the T-CON and the main board?

This is your T-CON board:
