Buzzing noise fault, Panasonic Plasma

[Mal X]

hi

i have a Panasonic plasma TC-P55XT50, (55'')last week it developed a buzzing noise, it's coming from the back of the tv; top left hand side and it varies in volume, it's worst with a pure white screen and silent with a dark screen, with a normal tv image it's about half volume, it reminds me of Capacitor coil whine.

is this problem easy to fix and does anyone know who can fix it.
thanks.

I never got the tv insured so it might cost a lot of money, but on this forum right now the buzzing is fairly quiet...

it's only really noisy from the side or the back and especially if the screen is pure white

fixed it, i took the back off and tightened the screws on the top right circuit board.

it's now about half the noise as it was, because it was always buzzy anyway.

the back was hard to get off but i was surprised to see so little dust inside
