Question about HP PL4260N 42 in. Plasma HDTV
Most common issue is power supply board fails--Plasma sets do not sell single parts--only a complete board---may need a tech or shop to look and determine what is wrong.
I can suggest things but need to know your skill levels--this is not for everyone....

I had the same problem today, Hp wanted $629+tax to fix. With a little mechanical ablity anyone can fix this.
1. remove back covers
2. left-hand side is the video board
3. two white fuses

I had an LG 37" LCD that did this to me. Turned out to be bad solder joints on the side button board. Just reflowed and it starting working fine.
But now that I think about, I had another set do the same thing, only it wasn't the button board. I had to upgrade the TV's firmware via the USB service port. Just needed a USB flash drive and downloaded the firmware from the mfg's website. There were easy to follow instructions there too!
