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.

This tv a CRT tube tv?Or a LCD tv or a Plasma tv?The tube tv,the video board that connect to the CRT tube head have problems.The Plasma or a LCD tvs.The main board,call the Tuner board is the cause,this board,that where the incomming broascating signal cable plug into it.CRT tube tv,old technology,must take to tv shop for estimate and repair.Plasma or LCD tvs can tries websites like Shopjimmy.com or Ebay.com to buy a refurbish Tuner board for the replacement.
Yeah, I was going to suggest power supply issue. Plasmas IMHO, are not worth spending the money to fix. Its the reason why they are so cheap these days in comparison to LCD's. I had a 50" Samsung Plasma that went out on me within 2 years (E Buffer board and XMain problem). Its not about the manufacturer but more about the Plasma technology. Do a few searches about plasma and you will find a lot of problems with these tv's. Id say cut your losses, sell the TV for parts and buy a more reliable technology
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.
it you have a repair skills you need to open the TV and make sure all the ribon connectors around the circuit boards are proper connected and if all seems to be ok, the DG board will need to be replaced.
If you dont have any repair skills I would recommend you to take you TV to a repair shop since this is complex repair
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...
