Question about RCA RT2770 Theater System
Have a RCA 2770 that is making a humming noise, just started recently. I did what is suggested. Made sure it was grounded, speakers were not to close. Last thing I did was take all the cables out in the back of unit and than plugged it back in still getting a humming noise. Is this something that is inside of the unit and if so what?

I have an RCA model D52W26. The green light comes on when powered on but turns off within seconds. No picture, no sound. Just a squealing noise then nothing. Any thoughts on a fix?

There is a short circuit in the high voltage circuit. the transformer who helps to create the high voltage or his power transistor is damage. replacement needed. the repair is not expensive, because the parts are average repair. Ask for an estimate.

buzzing noise is cause by small electrical arc inside the unit or a problem in your audio circuit.if you can open the unit up and check if its an electrical arc.

If its humming no matter what on all inputs, that means the internal electronics are worn out or damaged. This can be from a number of different things and isnt worth trying to have it fixed do the fact it would cost more than just buying a new one.

If this is a DLP set, which I suspect it is....you need a new color wheel. Common problem for these sets. If you don't have an extended service plan, about a 300--400 fix, in home.
