    After shutting it off.I have to wait 20minutes before it will come back on again.Even if it has only been on for a few minutes and is shut off it will not start back up again and the red light just flashes on and off???

    My set does the same thing. We were watching it, the screen went blank, and no sound. The red "power on" light would come on and then it would go off. If I left the set on this light would cycle, on and off for as long as I left it on.

Tv shuts off, when turned back on, the green light keeps blinking and tv wont come back on. if you leave off for a few min. the tv will come back on. then the tv will shut off again after a few min.


One of two things...first hold power button while you hold the up button on your remote, this will reset your tv to manufacturer's settings....you could have sleep timer on.....if this does not work, you have to replace the lamp, my tv did the same thing and it happened to be the lamp. Hope this helps, good luck

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!

RCA Projection TV won't turn on


Ok you got you a Rca ITC222 I See ALOT of these things. To start the troubleshooting.. UNPLUG the set for a min of 30 min the plug back up. ( I have never seen this work) If the set stil fails to come on then you have a processor lockup. The first thing you can conclude if the light flashes is it is NOT a FUSE. THe sets processor has determined that a safety condition has occured and shuts it down to prevent further damage and fire. THe top cause of this include Horizontal output trasistor, flyback transformer and high voltage splitter. but There is about 25 different failures that can drive it into shut down. technicains have interface equipment that can read errors codes much like a car.
typical repairs on this set run 150 to 350... if you have to replace tubes...250 per tube +labor which runs 250 ... these set new cost 800 so unless under warrenty.. you got to determine if it is worth it.
