Manufactured feb. 2003, unit has all power functions but outputs no sound. Basic troubleshooting done, no solution. Checked fuses, fine. Any suggestions?
I had the sane problem: No audio out from any source. Although I was unable to find a schematic or service manual, I did find the defective part was labeled on the circuit board as Q401 and replaced it with RadioShack part number 276-2009 (MPS2222A NPN Transistor TO-92 case NPN silicon). This is not an exact match, but is available at most RadioShack locations for under $1 and has fixed the problem.

I had the sane problem: No audio out from any source. Looking at the schematic the only component common to all audio outputs is IC401. Pin 24 of IC401 should be 6.6V; it measured 0V. The trouble was a defective transistor, Q401 in the Vs regulator (Q401, Q402, and Q403). Replacing Q401 with a better quality transistor pemanently fixed the problem.

I had one of these in the other day for warranty repair. Same symptom as yours. Maybe you will get lucky and have the same problem. Check IC401 pin 24. It is a surface mount chip on the board sticking out in the air above the tape deck. It should have about 10v. If not I found that although none of these parts checked bad changing them fixed my problem: Electrolytics C411 220uf 16v and C410 47 uf 25v and D402 p/n 248145 (7.5v zener) Q401 p/n 212671 (ktc3203y or 2sc3203y)

My cousin have the same unit RS2620 without sound, I accidentally plugged it into 220volt mains but the input voltage is only 110volts so I burned the transformer.
Could anyone please give time to measure your stereos working transformer outputs specifically RED-BLACK-RED wires and post it here because I will have the burned transformer rewind into 220volts input and continue repairing the no-sound problem that we also encounter here. Thanks in advance.

If the unit appears to function properly, moves tape etc, but no sound, plug in a headset and see if you have sound. If you do the power amplifier has a problem. It could be that it is not getting power, has shorted outputs, or no signals to the amp. These units tend to have bad solder joints and probably half the time resoldering all the joints in the suspect circuit solves the problem. If that doesn't work you'll need an O scope to trace the signal through the system, provided you are sure the amplifier is getting the proper power. Good Luck.

Home stereo has power and no sound

Its a fuse problem. take the back off and the bulb fuse needs replaced or maybe the foil trick

I have a RS 2620 and I'd had it for over a year, just used it as my radio and my theater sounds connected to my Satellite Receiver, next thing I know is, I've turned (on) the radio and the sound blow on both sides of speakers, It still have power on! not sure what to do next, it happen to me before, I had to use the Blower to blow dust out of radio and replug it and it works, and then within a month later, no sound from speakers. Any clue?

I found the Q401. Its near the edge of the middle horizontal board. I'm trying the same thing Myself, and I'll post the results- Thanks to all the folks out here with great ideas!

What's the voltage on the two red wires from the transformer to the amp supposed to be? I think that's the reason I'm not getting anything out of it, because the headphones do work, and I'm getting audio down to the amp.

I have the same problem no sound. I have replaced the 3 capacitors 2200mf without success. It must be another problem.

same problem, one year old and played twice then quit, everything works but no sound not even in the headphones...
Same problem, power works fine, but no audio. I reconnected the speaker wires and that didn't do anything either.
My RCA RS 2620 has power and all functions work, but has no audio and no headphone output. I am not very handy with repairs. Is there an easy way to repair this problem and where do you get the part(s).
Thank you,
Sally
Same problems here. However having scoured the boards. There is no Q410 transistor.
In fact there are almost none of the mention (to be replaced) circuits IDs.
Q401 i meant to say.
I have the same problem, ready to chuck the dang thing in the street.
Yah, one day it just stopped outputting sound... I plan on getting a new amplifier because the speakers are probably still good...

where is it the IC 401 located? how does it looks like?
same as everyone else, power to the amp, no audio (headphones, stereo output, speakers)...is there a place where i can get step-by-step instructions on how to fix this? i'm not very fluent in circuits language
I checked all the reg transistors and they were good.Just resoldering the area worked.
I like everyone else have the Rs 2620 power works fine headphones work fine but no luck when speakers are attached in rear of the unit..... This makes 4 different home stereo system since last Christmas I have had just stop working. This is so not cool I just want my tunes back..HELP!!!:*(
