mitsubishi wd-52525 tv problem

[mk]

Hi,
We have a mitsubishi wd-52525 tv which has starting acting really
weird the last week. The problem is that the device menu command on
the remote turn off the tv within half a minute or so. Volume/mute
buttons on the tv work. And if you press the device button on the
remote the volume/mute stop working and tv turns itself off within
half a minute. The tv menu button works but after getting the tv menu,
trying to go into audio/video icon does the same thing. This problem
is not isolated to the remote. If I press the device button on the tv
itself, I get exactly the same behavior. I have no idea what's going
on. Any help ? The bottom line is that I am stuck at watching the dish
but can't change to Xbox to watch dvds. I got the service manual on
ebay to see if there is I can figure out but I'd appreciate if anyone
here has any suggestions. It seems as if the device button on the
remote or the tv cause a short ? somewhere and the tv turns itself
off. Any experience with anything like this?

Thanks.

Hi
. Initialize settings by pressing "menu, 2, 4, 7, 0 enter" after
settings have been initialized press the system reset button on the
front once the LED stops blinking, reprogram the netcommand and tuner
settings. 2. (Initialization and reset does not help) Suspect the DM
PCB part # 934C116002

Thanks a lot. Initialization & reset took care of the problem. Now
everything is back to normal.
