My DTV shows nothing but a Blue Screen. It was working and then there was a pop and the blue screen appeared and that all there is. The regular TV, Video and game channels all work perfectly. I do have an external HDTV reciever that is working.

Re: MITSUBISHI WS55809 Blue Screen
I'm not clear on this. When does it show a blue screen? When you have it in HDTV mode?
A Blue Screen means it's not getting a signal (or the signal is very weak, resulting in more static than picture).
If it is a blue screen for HDTV, how are you sure the HDTV receiver is working?
If you can answer those questions for me, I should be able to track down the problem. I'm not sure which direction to go yet.

This means nothing specific, try to load Last known good configuration, by holding F8 key right after power on, until it shows Windows boot options. You should also check memory, hard disk drivers and viruses, but this is much longer explanation, so ask if needed.
hello! Blue screen(bright blue) indicates an absence of signal. If you have "on screen" display characters: menu, channel ##, volume bar, etc, your set might be configured for digital antenna settings, or DTV, "air" mode. Then, you won't be able to get cable channels through. If your "blue screen" is dim and there is no any characters, then your Y-sustain module is bad. Especially, if you have encountered loud "pop" shortly before "blue screen" appeared. Then, it's a major repair with board(s?) replacement. If you can handle that, get back to me in a next session. I will guide yourself "how to". Thanks, Alex.
Follow up on No DTV tuner after unplugging it a month for vacation. After I let it set plugged in for about 2-3 days it started working normally again and has been fine ever since. I hope this may help someone else. Genez 6-7-09
the left large button controls a dozen different ways your set is hooked up,easest is get the monolink cord at any store will need a dvi hdmi.if not keep rolling the left large button,if you have a blue screen on all your inputs ,There has to a man around to plug in the right cord.
also check resistor values on the chips and resolder the tuner as this can cause problems as they heat up , then replace any electrolitic capacitors in the video circuts selector ic
i will be back to see what you get
