Question about RCA RS2620 Single Cassette Deck
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)

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 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.
