I already figured out that my flyback transformer was bad, this is an ongoing problem with a lot of RCA CRT televisions because RCA used very cheap parts in order to save them more money, rather than making there customers happy with good quality parts, and my TV was made in MEXICO, and that my friends is why we the American people are getting screwed. (Shame on you RCA)
I have repaired many of these; if a high pitched buzz when you plug the set in---flyback and horz. output transistor are bad--transistor has a generic number on it--Flyback is location number LL05, part number should be 257805---you will find RCA no longer has this part--most now are replaced with an asti #2078----CHECK the RCA number on Ebay---company I get them from is Suburban Electronics---Flyback and transistor are less then 30 dollars for both.
If it weren't for the high pitch whining noise. I would say it probably is an internal fuse inside the chasis. It is rated at 1.5 to 2.0 amps. With the whining noise it sounds like a trouble shooting bench
job. Problems occur when a electrical/electronics device is turned on and turned off. Inrush voltage,
when it is turned on, can go up to three times more than normal. This also happens at turn off. Solid state components usually fail at this time. I don't feel that this is a problem that can be fixed in the home.---BBB
This could cause a problem, because modern TVs and most other entertainment electronic goods, have a small kind of computer chip, but there should be a Reset button probably inside the set!
If you feel confident about computer chips you may be able to find the button by tracing the circuit.(Disconnected from the mains).
Another idea is if there is a small button cell or battery inside, then try disconnecting it for a day.
