It could be, that would be the first thing i would do to rule out I would first check for loose connections on the board.

Toshiba 40h80 red light blinking


I would suspect the problem is in the convergence circuit---only one simple way to know---get at and un-solder all 18 pins on both the STK chips it uses.

Once they are free try to turn set on--if it comes on one of the chips is bad and both will have to be replaced.

There is no picture or sound


check your lamp, if lamp has been replaced then re-set the lamp timer, if you hear a clicking or buzzing and no picture is probable that you could have a ballast problem. I'd check the lamp first though.

That is a projection TV and the lamp in the projector is probably burnt out. Look online for a replacement. Good Luck.

Sound, No Picture


The only thing you can do is to unplug the tv for 30 min. Then turn it back on and see if that fixed it. If not call a repair man, you are most likely missing a power supply voltage or deflection voltage.
