This is an old Sony PFM42b2 plasma (8 years) but with only 2,400 hours of use. It's been working just fine with a hard disc media player at 1080i using one of the RGB inputs (iNoi hard disc media player).
All of a sudden the screen was filled with horizontal stripes (dark-no signal stripes followed by stripes with signal in them) from the top to the button. This happens on all inputs and at all resolutions.
I've tried everything but nothing has fixed it (I even made a reset on the epprom).
What could have happened? Can I fix this somehow?
Thanks for any input, I really can't afford to buy a new plasma right now (I would love an LED, but can't).
Happy New Year!
