Hi,

Ive got a problem with my 65" Plasma TV which occurred today, while watching suddenly I started hearing a loud Static sort of noise coming out of the TV, after a few seconds I turned the TV off and sound stopped. I turned it back on and as soon as the backlight of tv came back on the sound starts up again, sounds really horrible so I turned it off again and un-plugged from the wall.

Anyone know what could be the problem?

Thanks

First thing I'd inspect would be the fans. Use a mirror if your space is limited (but ideally you'll want to be able to put your ear to the location of the noise).

Anything beyond that is going to require servicing.

well I sent it off the Ascot TV in chch and they checked it out and found nothing wrong, it wasn't making the noise at all. They tightened all the screws etc and rung Panasonic to see if they ever heard of anything similar. Apparently they heard of one similar case and recommended replacing some caps and diodes etc so Ascot did and checked the PCB boards for dry joints and found nothing wrong at all. So they delivered it back to me today and we plugged it in and all was running well....for half an hour......

Static sound has returned so I disconnected all the HDMI inputs etc and just left power cable plugged in and still sound remains

I took a quick video trying to show off the sound http://www.youtube.com/watch?v=M5dWChmN7jo

About 2.5 Years old. I would expect you'd have some recourse under the CGA through the retailer. 65" TV is a big ticket item and any reasonable person could expect it to last more than 2.5 years without fault. And the VT is the premium model.

It does sound like a dodgy power supply to me, you're best to claim this under the CGA.
