RCA Model STAV-3870 Receiver

I was playing loudly and after about an hour, it shut off. It will not come back on, only the standby light turns on, the relay clicks but nothing comes on, no display or sound. I checked the internal fuses and the 2 main rectifiers and they are good. I tested and it seems as if the main transformer may be the problem. Not getting any dc current output to the boards. Any ideas what can be done? Repair costs etc?

Very likely that the internal thermal fuse opened on the main power transformer. With the power cord unplugged, Check the resistance on the ac input of the transformer should read less than 10 ohms. Contact me when you know. I might be able to find one.

Why is my RCA STAV-3860 not coming on?


It sounds like the unit is getting power but is going into standby mode due to an internal fault. Sadly, newer receivers these days are not designed to be repaired but replaced!

Rca receiver overload message


Power the unit off , Disconnect all the speakers ,power the unit back on and check to see if you get the same message, if so one or all of your speakers could be bad. This message appears when there is too much load on the output IC's,generally causes shutdown. Also try blowing the system out with canned air, And removing anything that prevents the unit from getting enough ventilation.

Receiver turns on and sound, when playing xbox a grenade goes off and the receiver shuts off..


If it is like a big POP and it goes out, then the amp is blown, or wires in the back are crossed. The amp might be going into protection. Most amps say PROTECT when that happens, but some just have standard breakers that shut it off when it is too loud, or wires are crossing. Check for that, and if it continues, then the amp is probably blown

RCA RT2250 consistant shutting off in Satalite mode.


Mine will always just turn off every minute or so after a hard shut down(ex: power outtage). I have to turn it back on and then hold the set button for a few seconds, then it stays on, until i turn it off manually, since the remote won't turn it off.
