Re: vizio vo42oe 42"lcd heat problem
The caps look ok visibly, could the problem be internal? Where are the reulators located on the power supply?

I didnt smell anything, like the burned electronics smell. In the thread topic I said heat problem, it actually was more like when the tv finally warmed up it would turn off and on off and on. Then like I said earlier in the thread now its just back light no on and off just solid backlight.Leave a comment:

The tv doesnt make any popping noise, I have looked at both boards very closely and all the caps look fine no swelling or bulging. Someone on another site had said it was a heat sink problem, but that didnt seem to make any sense to me but then again I dont repair electronics for a living. So if...Last edited by Grn94hatch; 09-17-2011, 05:30 PM. Reason: Trying to upload pics and cant for some reason
