RCA 3870 Receiver problem..RE/RE

Ok, I think I did what you said...but what I did do is plug it in and checked to see if I had 120v at the primary terminals on the Power Transformer Pioneer # ATS7263, and there is 120. However, on the DC side, I get nothing. I set my voltmeter to 50v DC to check, and even when crossing the terminals in all directions, not even a bump. Those 3 "little" fuses on the AC side that are underneath the little board soldered, I set my meter to ohm, and they all 3 have resistance while unplugged.

Am I correct to assume the power transformer is dead?

On the secondary of the transformer you would still have an ac voltage. The dc voltage will be after the bridge rectifier.

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.

I have a Niles SW300 subwoofer that continues to blow fuses. I have replaced the fuse, but when it the power is plugged back in the fuse immediately blows.


ok, temporary cheap fix... (i mean in a ******* engineering kinda way ;-) . . . )
since your primary receiver has a sub-out RCA plug, you can hop into the local pawn shop, buy a cheap receiver and an RCA line splitter, and connect the primary sub-out to the CD or any input EXCEPT phono (resistance is different on the phono rca's). remove the plate from the sub and run the speaker wire from the "pawn stereo" directly to the speaker. replace plate on sub to keep box sealed, and adjust receivers to desired level of bass & volume.
You have spent $50 and now have a decent sounding system again.

Stand by /on led lights up but that is it. Click sound when ON is pushed. It is like it won't power up. Took off cover two fuses inside appear fine.


Check the main power transformer.

ohm out the primary side should be about 2 ohms. and check for 120v ac when you power it on.

If 120v is present on the primary side check for ac on the secondary. if none you need to replace the tranformer.

If it doesn't have 120v ac on the primary there is an open fuse or bad solder connection.

If you find an open fuse check for a shorted output transistor pair.

good luck

UNIT HAS ALL POWER FUNCTIONS BUT OUTPUTS NO SOUND. ANY SUGGESTIONS. HAVE CHECKED THE SPEAKERS HOOKED TO ANOTHER UNIT SO I KNOW SPEAKERS ARE OK. MY SON IS BRAIN DAMAGED AND NEEDS TO HAVE SOMETHING TO LISTEN...


This comes to mind:
Did you perhaps connect the rca jacks to the record in instead of the play out?
Maybe the rca cable is not plugged in at all on either the receiver end or tape deck end.
Have you tried using a different rca cable?
Did you select the right input on the receiver?
You may try using a different input on the receiver.

I know these sound obvious, but they may fix the problem.

Where do i plug in my 120v charger on my garmin nuvi 760 gps


Hi I have this model too. You must have the 120v charger with the Mini-B  port on it. It plugs into that port on the bottom(PS3 controllers cameras, and other Computer devices often have a mini-B USB

My sx-315 pioneer receiver overheated and shut down.


Probably the thermal fuse in the main power transformer. Check for ac on both the primary and secondary of the transformer. If you have 120v ac on the primary when the standby light is off and nothing on the secondary you need a new transformer.

RCA Model STAV-3870 Receiver


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.

RCA RT2500 audio amplifier will not turn on when I push the on button. I reset all the plugs inside and checked visually the fuses they seem ok. Would like to know if there is a reset jumper on the board...


Verify 120v at wall socket. Plug 2250 into mains, if not so already.

QUICKLY unplug and plug back in the unit. That should put the unit into DEMO mode, at which point you can press the (now red) power button and the unit should function nominally.
