My Jvc plasma 3+ yrs old w/8300 hrs started showing neon green snow around the edge of the picture, then it got worse, now it's dead. When I try and turn it on it flashes a powerful electrical pulse with pure white screen for a split second and then stops. It continues to do this every five seconds (almost like it's attempting to power up) until I shut the main power to it off. Any repairmen or specialists out there that have heard of this??
Oh yea, model # is JVC GM-V42UG. Not sure where to find the chassis #.
Thanks a lot.

You are proberbly using RGB leads, wich is red green blue, each colour runs through each cable, have a look at your cables maybe one is loose, or damaged. check on both ends, but the cables MAY NOT be red green and blue, but the terminals that the plug into will be.
I have the same green dots that are seen especially when the bacground picture is dark or black. Mine does not seem to be changing when it warms up, and I also get it on my digital cable as well as on any DVD's I play. Please help with any advise. I think it was always there, but I assumed that a dgital cable upgrade would fix it - I should have known better...
Looks like green horizontal lines, this is definately some type of filter problem. Looks like in the HV or Horizontal are. It first looks like turner problems but you say it's on all inputs. Then if that's correct it's not the tuner.
