I have was given this old-ish set when it finally gave up the ghost. It's clearly had heat issues, as many of the vent holes were clogged with fluff.
Prior to dying, it used to take a while to come on from standby- starting up, tripping then trying again, for up to 20 minutes until it eventually stayed on & worked fine for the rest of the night. Until of course one day it just wouldn't start up at all.
I checked the PSU for the obvious (and not so obvious) sick electrolytics & replaced about half a dozen with new low-ESR types.
The set now starts up first time, but only displays a very faint raster (audio OK) and no menus or graphics.

I spent many years repairing CRT's (when it was still worth it), and even the odd LCD set but plasma is all new to me & apart from checking the power rails for ripple (which I have & it's pretty tame now) I am at a loss. The set is probably 5 or 6 years old & not worth a fortune but the picture was ok before it died.
Any hints would be appreciated before I send it to that big wall bracket in the sky.
