It should be marked Q401 on the printed board. It will have 3 legs you need to desolder these and then you can read the number to order a replacement. Make a note of how the transistor is fitted before you remove it. For example if it is flat on one side and that faces another part then when you put the new one back it should go in the same way, with the legs matching the holes in the pc board.

Most times when this unit chirps the horiz output transistor has shorted. If I remember correctly the transistor is Q401. Some times the flyback transformer can be bad as well T401.

I had the same problem with mine and the fix for it was to replace the Q401 transistor on the main board. I used a NTE382
replacement and has worked fine ever since.
Hope this helps

Buzzing noise


Of course it will stop buzzing when you mute the speakers. From the limited description, it could be anything from a power supply to loose wires in the system between the speaker leads and the motherboard. Best bet is to take it in to a technician and get a pro's answer. If he wants to charge more than what it's worth to you, get a new one.

Rca rs 2620 power but no audio


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.
