Television won't power up


It sounds like the high voltage circuit got damp and arced. This arc caused the horizontal output transistor to short.
You might try replacing the output transistor if you're experienced in this type of repair. If not then you need to take it to a repair shop.
The "whistle " you're hearing is the power supply indicating that it has a short on its load. When the power supply has an over load (short) its frequency drops down when your ear can hear it oscillating. This type of power supply is a switching power supply normally operating a several thousand hz(cycles) which is out of range of human hearing.

RCA F31672ET No Power only a whining noise when plugged in Please help


Most likely you have a bad flyback transformer and shorted horizontal output transistor. The whistling sound that you hear is the power supply telling you that it has a short in one of the circuits it powers. Most likely the circuit mentioned above. Stargazer
