Question about LG 42PG20 42 in. Plasma HDTV
My LG 42PG20D, when first turned on picture and sound quality are excellent. After unit warms ( about 10 Min.) the picture quality is lost. picture is still visible on screen but very poor quality, like paint mixed into water, it appears that a component when warmed up is failing. if set is turned off and allowed to completely cool off, it starts with perfect picture again until it warms up then same problem . what item would you suggest is failing?

SOURCE: Invalid format
Try rechecking all wire connections for proper placement and fit too and from the tv.
Try adjusting the video format on the DVD, flip through 480p and 1080i. See which format works best with your tv. Do the same with Wii.
See if this helps.

It sounds to me like there's a few bad capacitors on the main power supply board,take the back off and look around for any electrolytic capacitors that have puffed out tops.
If this helps please give a positive feedback
