I have a seven year Plasma TV HP PL5060. When I turn on the TV, I have sound but no picture, the screen display (power on) is a snowy blue screen and vertical pink stripe. What is causing this problem and how can I fix it cheap. I can afford a TV repair man at this time, because I am laid off from work. Thanks.

Does it look like the bands in the picture? it is defective panel.

no the picture just leaves tv and i get black screen

This is a Tcon board issue.

The cause is one or more shorted transistors either on CRT board or on main or both. The colors are red,blue and green, you have a transistor for each and a bias trans. check each there are 6 in all.

it's called retrace lines ,your screens are set to high or focus block assy which has the screen adjustments on it also is faulty
