Hello shun09,
This problem denotes a possible shutdown circuit activation caused by excessive current flow from the IHVT. This might be caused by a shorted horizontal output transistor, or a shorted and or open transformer (Applies to CRT type TV). This also can denote a switching power supply shutdown circuit problem (Applies to LCD or Plasma TV). Both of these issues should be checked by a qualified TV technician.
Thank you,
I hope this helps, Shuttle83

SOURCE: when you turn 'on' the tv...the tv continuously 'clicks'

The clicking noise is caused by the relays on the power supply board trying to power up the system. Your TV has detected a problem that's causing the power supply to shutdown. Someone knowledgeable in electronics can track down the problem. The SOURCE of the problem could be another board other the power supply.

Is the clicking through the speakers or from the back of the TV? Do you get a picture and sound? It might be something that is warming up and expanding as it would normally if this is the case

replace CP150 and CP114 you can get them at the following link they also have the ITC222 service manual which is listed under Thomson as Thomson makes your TV for RCA. The Capacitors are listed under the RCA parts and they do send instructions with pictures of where the capacitors are located as well as how to remove the board.

Will not come on it only a clicking sound from part no. 0mron 0584H3


I had the same problem with my tv, same make and model. I first continuously turn on and off my tv manually until I could get some kind of picture. This procedure took maybe five minutes. I was able to get a fine picture and sound, as if it was brand new! Other things to keep in mind, try to eliminate dust build up as much as possible.. Hope this helps out...

The clicking sound is the relay switch on the power board, it could be the power board or the logic board
