Re: Vizio VT420M No picture - component cooler fix

I still have sound. Mine works when first plugged in for about 10 minutes then no picture but I still have sound. If I plug in back in again after 3-5 minutes it's still no picture. If I wait 30 minutes it will work again for 5 or 10 minutes.

After it fails if I unplug it and spray component cooler on the mainboard it works almost right away. I normally wait 30-90 seconds before I plug it back in.

I'm posting this pic to help me identify this part. What's inside this thing and what is it? Thanks for...
