Hi All, I bought a 32ZP48 from Direct Digital last November and I must say it's great, picture and sound all brill BUT resently the screen has started to flash and the speakers buzz. It only lasts a split second and only happens once or twice an hour after the TV has been on a couple of hours but it's getting me worried. I've spoke to DD and they said my TV is 'out of sync' with my satilite, DVD and vidio connected to it, I should disconnect them retune the TV and reconnect. Sounds abit iffy to me!! Any ideas anybody?
