Expert: Nagy George Date: 1/3/2007 Subject: Toshiba Model TP50650 Problem
Question I own a Toshiba Theaterview rear projection tv. Model number TP50650. Chassis TAC 9752. Serial number 81994513.
Until a few days ago I have had no problems with this set at all. Then, when turning on the tv a black square that covers most of the screen pops on. I can see around 2" all around the picture. I have isolated the problem to the tv and not to any of several input signals, (DVD, VCR, etc...) For the first few seconds of power up the picture is fine. I can press the EDS button and the screen is fine for approx 30 seconds and then the black square pops back up. This almost appears to be a setup problem, but so far I have not been smart enough to figure it out. Any thoughts or suggestions would be greatly appreciated.
Answer Steven, I am not sure what it is but what I would personally try is disconnecting TV from Mains overnight hoping that it would reset itself.
No luck?
I would check on how to access the installer's hidden menu on this model as it might be related.
