Can anyone help me? I have a 28ZT29 idTV and I think it's fantastic. However it has developed a very annoying fault. When I turn the TV on the digital tuner won't work. There is just a blank screen. The TV menu works, but the DTV menu will not. During the time when it doesn't work, if I watch analogue TV or a DVD or video, every so often the screen turns blue for about 2 seconds and the sound goes off (except the digital audio which continues). It then displays the current channel or EXT as if I just turned to that channel. It will do this blue flash for a varying length of time, although it does it more if I've been away for the weekend and not used the TV. I called the Comet engineer out who refused to fix the TV as I had a weak analogue signal which meant I had a weak digital signal which in his opinion was the sole reason for this fault (despite the fact that it worked for 5 months previously). It (typically) did not do the blue flash for him and he did not want to speculate on what might have caused something he had not seen! Has anyone had a similar experience with their Strata TV? Can anyone suggest a fix, or something I can say to Comet to get them to look at it properly? Can I demand a replacement? I appreciate your assistance.
