My plasma was one of the John Lewis Price match specials from a year ago and has been fantastic, no screenburn or snags of any kind despite heavy xbox use and it being treated like a normal TV. Just lately however an annoying problem has developed, if the plasma is turned off after watching a dvd or the xbox has been used, when it is switched on again the tuner box just clicks on and off without "waking" the screen up. The only way to get it all working is to wait several minutes untill it has clicked itself crazy and seems to reset itself or unplug everything and hope for the best. I have checked all plugs, cables etc to estabish that there are no loose connections. Have there been any reported problems with the tuner boxes on the pd423000?
