SOURCE: 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.

Hi, This could be several things as the power goes everywhere. Long distance troubleshooting so hang in there. First try a cold reboot by unplugging and replugging after 30 minutes. If nothing check P1 on the light engine for the following voltages: pin 2 5vdc, pin 3 3.3vdc, pin 9 3.3vdc, pin 12 12vdc. If any of these are not good it is the formatter board. If all are good, does the color wheel spin at all. If this is OK then check J4 on the light engine, the ballast enable line should be 0 vdc in stby, .5 vdc at turn on, and 2.5 to 3.25 vdc in run. If good, is the light engine trying to fire the lamp? If not, inspect the J4 connector and the lamp power supply, If they look OK then the lamp ballast is probably bad. This will give you something to do for now, Good Luck!

first check all fuses they are small, square ,RED and can be confused with the square small caps. the sizzling is prob. the flyback transformer (what the h.v. wires from each tube plugs into) if you are only getting green then tv shuts down or is dead now. i would replace any bad fuses and replace the flyback transformer. also make sure you do a very good visual inspection of all the boards.
