Hello, I have a Pioneer PDP 434HDE Plasma...recently the media box was away for a service and has returned with a slight fault. Perhaps someone can advise as if this is normal. Having problems switching on the satellite receiver.... Switch Sky on, switch TV on & the screen goes to standby? The screen does not like the TV being switched on before the Sky receiver? This may not seem like a huge problem but its getting more difficult to turn on Sky as the TV just seems to go to standby all the time? This is my first time on the forum, any advice out there?
