Question about Sony BRAVIA KDL-52W3000 52 in. LCD Television
I was watching it and suddenly with no warning I could not see the picture any more. A message saying "no channel available, please scan" appeared on the bottom of the screen. When I try to scan for digital channels it scans but when I try watching TV in digital form the screen is black and again, it says "no channel available, please scan". It works on analogue. Does any body know if there is some kind of setting that I might need to reset so the digital system on my TV starts working again. Thanks.

You either have failed 24vdc power supply section or failed backlight inverter board, check for 24vdc first, look for caps with leaking/bulging top.

Your TV has a dual tuner - one for analogue and one for digital although they are contained on the same tuner board. It's possible that the digital tuner has failed, in which case the tuner board will most likely need to be replaced, but often this problem can be resolved with a "hard" reset. Turn the TV off and unplug it. Remove all the cables from the back, leave it for at least 5 minutes and then re-connect only the cable from the tuner source. i.e aerial/antenna. Make sure you are in Digital TV mode (DTV), then run the channel scan again.
If it works turn the TV off, re-connect all of your other devices and you should be able to resume using the TV as normal.
If this doesn't work, you may need to have the digital tuner replaced. The analogue and digital channel feeds are from the same source. As the analogue channels are working there is no obvious fault with the feed or cables.
Please try this first and then post back for further assistance if needed.

I have the same problem, the only solution I found so far is to disconnect the TV from the mains supply - not very comfortable. The problem seems to happen more and more frequently.
