My Rca rtd3136eh does not power on. A red light comes on but thats it. Can anyone help?

Check and replace the damaged component/s at its main board. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

You are in the wrong category

Bad main logic board. Probably won't be able to find it. You can try Encompas Parts. Good Luck to you.

It means that the subwoofer is blown. The red light is called the Protect light. Disconnect the speaker wire from the amp and then turn the amp on and see if the red light goes away. But if as soon as you hook the speaker wires back to the amp and the red light turns on that DEFINATELY means the sub is blown.

you will need a line-level converter to use this subwoofer- it is a rectangular-shaped box with wires coming out on one end and red-and-white RCA plugs one the other. The end with the wires coming out will hook to the receiver, and the other end will need to plug into the sub.

ck capacitor cp150 if it is bad replace 2 other caps in same circuit 2200uf 16v -220uf35v cp111 cp114?

Flashing led..in protect mode..internal shorted component.
