Hi folks, My Hitachi C24W1TN widescreen TV has recently started doing a weird thing. A couple of minutes after switching it on the blacks slowly turn blue/grey across the entire image. This occurs on both analogue TV and on the RGB scart input from my Nokia OnDigital box and Sony DVD player. The strange thing is that I can cure the problem by switching the set to standby for a couple of seconds and then back on again. The blacks become black again and stay that way. Weird. Should I be worrying about this and getting an engineer to check it out? It doesn't look like the tube's about to go kaput - I've only had the set about a year and a half. Any advice appreciated... Doug.
