    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...

  • Fireman290 Nov 27, 2007

    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...

    "I had the sane problem: No audioout from any source. Looking at the schematic the only component commonto all audio outputs is IC401. Pin 24 of IC401 should be 6.6V; itmeasured 0V. The trouble was a defective transistor, Q401 in the Vsregulator (Q401, Q402, and Q403). Replacing Q401 with a better qualitytransistor pemanently fixed the problem."
    where is it the IC 401 located? how does it looks like?

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 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.

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?

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.

Where is the aux jack for the RCA RS 2620 bookshelf stereo?


The Aux audio L/R input jacks are below the On/Off button on the left side of the front of the stereo's main unit. The headphone jack is just below the input jacks. You will probably need an adapter to split the stereo output from the Blackberry (probably a 3.5 mm stereo jack) to the L/R jacks.

Radio Shack has the manual for the RCA RS2620 here: http://support.radioshack.com/support_audio/doc72/72312.pdf .

I hope this helps.

How to hook up my pc's audio to rca rs3531 to


In general, your PC's sound card (and its controlling software) will determine what it can connect to.
Even the most basic PC would have stereo analog output via the typical green 1/8" connector or a headphone jack that easily adapts to RCA pair for REAL audio connection. Any Line Level (AUX in your case) input EXCEPT PHONO would accept the PC's output. The output level would be controlled by the sound card software and settings.

Could you be more specific with your problem? It could just be that the lens is dirty. If not, trace your signal flow and make sure everything is wired and powered correctly.

Audio from tv is not restored by turning off power on headphones


It sounds as if you are plugging the base into a standard headphone jack located on the Television set.

RCA Headphone jacks (incl mini) automatically stop the sound output to the main speakers on almost every set I have seen.. or home stereo.. etc etc

In other words you can take a standard RCA jack.. with nothing connected to it.. plug it in while the music or sound is coming out the main speaker.. and it will cut off the output to those speakers..

If you set has audio outputs on the back.. preferably Fixed Audio Out .. you will need to connect your base unit to those.. turn your set volume to 0 and adjust the headset volume using the control on the right ear-cup.

If you have variable audio out.. you will need to go into your TV sets setup menu.. turn off the speaker.. and turn up the set until you achieve a signal and decent volume through the headset.

If you are missing these connections.. your current “work around” is your only solution.

Best of luck

Rca rs 2620 power but no audio


I need to see if the manual has any method of button pushing to get the sound back on. Otherwise, I am not an electronic type of guy that has soldering tools, can tell a resistor from a plug, etc. if that is what is needed to get the thing going with sound.

Tape shows playing but no sound


Is sound at the headphone socket?
Does the meter show audio output?
If the answer is yes to these questions check that the connections to the amp are correct and the amp is set up is ok.

RS 2620 has power but I do get any sound


If you are not familiar with electronic circuitry, I would strongly suggest you did not try to service the unit yourself. There are many circuit functions that need to be tracked and evaluated, any one of which could be the problem or one of the problems.
Please consider taking unit to to serviced
