C411 nd c410 radio only plays in the fm it has no audio in am at all.
Sorry **** - but the only way you can get values from a board is either TESTING them - or reading them off a Repair Manual or good board.
For us to spend $15-$25 on a repair manual for you defeats the purpose of this troubleshooting question.
We are in a crapshoot to earn less than half of the fee you are paying.
My suggestion is to purchase the Service Manual - and come back to repost any technical questions you have with the reference material in hand.
Good Luck with your -needle in a haystack- find (expert with a working board that is disassembled to read references off of just for you)
Please direct your refund request to FixYa - as experts do not have the ability to satisfy this request.
Did you check if the AM/FM switch if working fine ?
May be only FM mode works and AM mode is locked.
You may try replacing it and see.
Either the rheostat for volume has failed or the pre-amp has a problem, it could also be the playback head, but all these things are labor and time consuming and these types of electronic devices are cheap and in many cases no spare's are even available if they are not a generic part, that is not a 5th grade answer but a truthful statement.
without a factory service manual and wiring diagrams u will be just guessing, correct, and educated guess but a guess, that is really what we are doing, we have no specific manuals, we work from home and are not employed by Fixya, just trying to point u in the right direction, just trying to help, the is nothing, when i work I make $40+ (electronics tech) and hour, so this is for fun mostly.

Hi and welcome to FixYa,
Initially, I am not familiar with an RCA RS2620, and therefore would appreciate a copy of the schematic diagram. With your indulgence pls email attach them to <[email protected]>.
Let's try the basics, and I think you are on the right track. Common to any and all functions would be the amplifier. Even if the AM is faulty, FM & CD should still work. Your post indicates that the low volume is common to all. This being so, then probable faults would be:
But then again without the schematics could not be more specific. Would look forward to receiving the schematics then.
Good luck and thank you for using FixYa.
Its a setting problem or antenna loose PF.
check a full factory reset from the owners manual then try again also check the anteanna
Hi,
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.
Hope This Helps!!! Please Don't Forget to Rate my Response!!! Thanks!!!

U have to reset all settings to factory defaults.
then check.
Buy a new radio?
As you will have to check the parts with a continuity on the amp board because continuity will give the exact fault in the part as if the light in the continuity comes on that means that component is proper other wise its faulty if no light comes up.and with the meter you will have to check the value of each part which seems to be faulty.that will clear mostly all the faulty parts in the board and that has to be replaced.also check out if any ic seems to be loose on the board then this can create the sound problem so first to start just dry solder whole board and let it remain for some time that will make all the minor components on the board firm and tight then just check out if sound is coming.aLso if the connecting cables on the board have cut in them then the sound can be disturbed or low. thanks.
That is probably a defective ceramic filter in the if stage, or a setting problem.
If the Radio works fine in FM, but there is no audio at all, not even static in am, it is likely a fault concerning the if stage.
The if stages are the part of the circuit that filter the signal to eliminate the bad frequencies.
They use ceramic filters and that is the first part to test.
Alternatively it can be a problem with the AM tuner circuit, but in that case you should have static, and I also understood you have already done some job in there.

Usually answered in minutes!
tell me how to do that
give me some numbers on the board so I know what to change
the two solution I have been sent thus far are terrible something a fifth grader might give for an answer
first post the numbers of the ceramic filters you are referring to and also tell me how to reset all settings back to the factory default settings.

my problem is with an RCA RS2620 am-fm radio,dual tape deck and a 5 place cd player.
I have low volume but it is adjustable,when I recieved the machine for repair it had no sound but after changing Q401,D402 and C411 then I started receiving the low volume I never checked trying it with an earplug but now when I try the ear plug it is the same as what is coming out of the speaker for volume.
also I don't hear any noise when I switch the radio mode to AM
the cd player works but has the same volume as the FM radio.
I went to electronics school in 1954 but never persued it as an occupation but did run a tv shop for years along with being a carpenter.
I don't have a scope anymore to trace the signal but I believe my problem is on the amp board and again I am guessing but think it is a voltage problem but with out something to go by I have no idea what the voltages would be.
also on IC401 where is pin 24 located i know the dot on the IC is number 1 but with out a data sheet for that IC I have no idea where pin 24 is so I can check that voltage if you guys have the service manual or a schematic I sure would like a copy of it and would be willing to exchange some schematics you need for some I have.
please let me know what to do.

please let me know what to do. can you tell me the part number for IC501 and IC502 I can't read them. I have a schematic for a RS2526 that is fairly close to mine but not the same,If you guys need it I can scan a copy and send it to you it was taken from a RCA cd so it is not in pdf.

I would still like to get some help on this RCA stereo so Far I haven't been told anything I didn't know If I had the service manual I would fix the thing myself.
Can't you guys try a little harder
dick2256
if that is the case repat $9.99 t0 my paypal account like you said you would if I wasn't pleased.
