Magnavox tv model #47MF437B/37 - when we turn it on the on light turns red and won't come on and there's a chirping noise coming from the back. Can you please tell me if it can be fixed?

A 'chirping' sound usually indicates a bad startup cap, a shorted diode on the secondary of the transformer, or an excessive load. Because of the usual design of these power supplies, it's probably not a startup cap.

I Have a Magnavox 42MF531D with no picture and when it is plug in, I hear a chirpping sound.

Problem will be either in power supply circuit board or something loading power supply down.

Someone first would need to test voltages in and out of the power supply to see what is wrong.
