Default Snowy Picture on LG Plasma TV


This could be internal power supply noise. If you are experienced at
TV service you can use a scope and go through all the power supply
distributions to see if any of them are noisy.

Another cause could be a defect somewhere along the digital signal
path. There could be some system clocking errors, or some noise
generation taking place.

Does anybody know why this might be happening or what I can do to
correct it? *Thanks.
