Picture disapears after few minutes

I think the electronics inside it have failed. My guess is that because its the picture only, it will fail in the same way if you play dvd into it for the same amount of time. The failure happens after it has warmed up, if you take it out into the cold you may get 1 minute more before it fails.
It needs replacing, its not cost effective to repair something like this, the failed parts may have partially damaged other parts in the unit so they could fail after a repair.

I HAVE 60 ' INCH FATBACK WHILE THE TV TURNS ON THE SCREEN THAT TELLS YOU , SETTINGS , STAYS ON UNTIL IT WARMS UP ....YOU GO TO YOUR REMOTE AND HIT MENU , IT DISAPEARS....BUT ONLY WHILE ITS WARM .

Got a heat related issue likely on main signal board---might be able to localize it (suspect a flat pack chip) with a hair dryer to heat the board just a bit.

When I first turn on the Toshiba projection tv the color has a strong red hue to it which clears up gradually

I would suggest when turning set on cold---turn color all the way off and examine screen as set warms up---if red to some degree but gradually becomes black and white the issue is either a "touchy" red screen control on the screen/focus block or a problem on the circuit board plugged to the bottom of the red tube.

I guess the real question is how long until it is normal?
