My rca model f36669 makes a popping sound and cuts off and back on

That's hi voltage arcing. Dangerous condition were a component has broken down and is arcing causing the power supply to 'crowbar' or go into over current protection mode. Call a TV repair pro for an estimate to see if you want to keep the set.

10-year-old 32" RCA PIP TV just blinked off one morning after about 30 minutes. It makes a continuous high pitch sound, and the on/off switch is completely unresponsive. I assume this is a picture tube and...

It's not the picture tube(especially if image was good b4 it went dead). The high pitch noise is the power supply whinning because it's shorted or overloaded. I just fixed one of these sets - replaced the horiz. o/p transistor and flyback estimate around $120.00-$160.00

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

the tv has one part of the power supply working this is needed to have the microcontroller ready to work. But the tv needs more than that for work im talking 'bout the high voltage power supply who is now damaged. the parts required depends on the diagnosis in the bench but at least two are needed. the cost of this repair of course depends in how many parts are going to be replaced, but i concider this repair kind of average in this technology.

A shorted horizontal output transistor or shorted flyback. If the flyback is shorted replace also its HOT.

RCA F36650 Television . . .

It can be repaired. It sounds like a bad high voltage transformer or something in that circuit. I would take it to a TV shop and ask for an estimate. It might be costly to repair.
