Youre going to need the deflection board as the high pitched whine if it sounds like a short chirp each time the power indicator lights for the 3 times is caused by a surge taking out numerous components on the deflection board.

Wont turn on!


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
