Humming is due to main filter capacitor have gone dry or defective. repace it humming will go. picture cut is due to less voltage going to vertical stage.coming froh eht(hor stage.) as main filter will cause main power supply to be low which will cause low voltage to hor.stage.

The repair of this problem will be near to or exceed the cost to replace it with a new flat screen. With TV prices at an all time low due to slack demand it is not cost conscious to repair it.

Rca 52 inch keeps shutting off and picture is curved

The curved picture indicates failing parts in the pin amp section and probably some faulty parts in the scan amplifier sections. The set is being turned off by the uPC because there is a fault indicated, and it is going in to protect mode.

The set will have to be properly serviced.

RCA 32 in TV no picture no sound just a beeping noise TV power is on

You have a bad flyback transformer and shorted horizontal output transistor. Your set would have to be taken to a shop to have these parts replaced. Stargazer

Turns on and off

You have a shutdown problem. The 3 times is a "3 strikes and your out" RCA feature that says there is something latching the set up. You will have to have a technician look at it. In this case it might not be worth it.
