Yesterday I experinced what I would consider a software crash in my Sony 50" Grand WEGA LCD rear projection HDTV (KF-50WE610).
Symptoms:
* Volume control / mute button, I can change the indicators for volume & yet the volume remained constant.
* changing video input 1-6 did nothing, I was left with the same thing on the screen. Changing to input 7 (DVI) would cause the screen to go blank. changing the input to anything other than 7 would display input 1 - which had a picture
* After tuning off & on the TV, the screen would NOT turn back on & volume remained constant. (That's when I called to schedual a service appointment)
* Later that night, when I turned out the lights, I observed an odd blue glow from the TV. So I unpluged it.
* When I pluged it back in - it was good as new!

it crashed & all it needed was a hard reboot? What do I do about the repair guy that's comming out on wednesday? All s/he's expecting to do is replace the lamp. I somehow doubt they'll be skilled in the art of tv firmware upgrades. It will probably be a big waist of time. :sigh:
