Ur high voltage FBT the flyback tranformer,a big black block of plastic with a gray wire connected to a board.The cap it dead.The FBT it useally it dead too,arching noise FBT not holding the high voltage.
sounds like the flyback which is the number one component that fails on that model. You need flyback 259296 and you can get a replacement flyback at the following with step by step instructions on how to replace it. heres the link. http://servicemanuals.vstore.ca/
my d52w19 chassis itc222 as posted most of the time wont turn on and the green light flashes three times every time it makes a small noise. sometimes it does turn on and you hear a little pop and the tv fires up. latley there is a really high pitch noise that will slightly change pitch if you move the tv or put slight pressure on the top or botttom rear part of the chassis. thanks for the help as I have seen that this has been posted before without mention of the high pitch noise.
I work on these at the shop alot(THERE THE TESTAMONAL FOR THESE SET LOL) ok these sets itc222 chasis from rca have a processor that shuts them down for one of 25 different resons. THe sound you describe indicates to me a few possibilities. the first thing i would check if i had it in the shop would be what is known as the flyback and the horizontal output transistor. if you are a tech. these set can generate pot high voltages so be careful. there is some times i have seen loose ribbion cables but that is rare
That high pitched noise you're hearing is the power supply telling you that it has too much of a load on it and lowered its operating frequency which in effect cuts its output way down! Normally you don't hear any thing since the power supply operates at a frequency that's beyond human hearing.
In an RCA this indicates more than likely that your horizontal output transistor is shorted and this short was caused by the flyback transformer shorting. This is a common happening with RCA's
You'd need to take to a tv shop and have it checked out.
