This fix is for those situation when the set light comes on and then shuts down soon after due to board voltage limits issues.
The follow fix worked for me and may work for you.
>>> DO NOT ATTEMPT IF YOU ARE NOT EXPERIENCED ON WORKING ON LIVE COMPONENTS AS THERE ARE POTENTIALLY DANGEROUS VOLTAGES INSIDE A LIVE SET THAT CAN CAUSE GREAT HARM IF YOU TOUCH THE WRONG COMPONENTS INSIDE!!!<<<
Over/under voltage signals will put this set in shutdown mode and can happen during a cold startup. The fix was at least $400, not really worth the money. Instead of junking the set I unplugged the board to board plug (should have 10 to 12 wires in the plug) so no shutdown signals would get through during initial startup. This was found on right side on vertical board, you can find a schematic on line. I turned on the set, the transformer came on warmed up and settled down. I was then able to plug the board back together while the T.V. was on and it works fine. I now leave the set on and change the input mode to an unused mode when I am not watching the T.V. or my kids are not playing their video games. If the TV fried, it was no big deal, it was junk to me anyway.

The RCA ITC222 chasis is a shutdown prone set. I deal with this television alot in the shop. The first thing too know is this set's microprocessor will shut the set down for 1 of 20 different reason for safety. The fact that the light comes on tells you its not the main fuse. ANd the processor is recieving power. It is detecting a problem with something else.. I have found high voltage issues to be the most likely problem but like i said can be many things. The first thing as a customer you can do it to reset the processor. uplug the set for a minium 30 minites and try it again(note i dont think i have ever seen this work) As a tech the next thing to check is the Horizontal output transitor. see if it is shorted. if those are ok.. then the troubleshooting begins.. The processor on these set record the failures and a technician with a special interface can read these codes to help. Some of the cuircits invovled also require this interface to replace.(SSB BOARD)

I had the same problem when I first bought mine. It requires a huge amount of electricity. Try and only use one outlet by it's self. I had a lot of other stuff on the same outlet, unhooked everything but the t.v., and tried again. Bingo! it worked
