Question about RCA RT2250 System

1 Answer

I have a RCA RT2250 and I have a green light on a circuit board

The green light comes on when first turned on than goes off after a few mins. When light is on I get static out of the sub and DSP modes but after the lights off I get sound out of front L-R and sub. Also power button does not work most of the time but goes on by tuner button.when turning on from demo mode the system shuts down after a few mins, but turn demo off and push tuner it will stay on.No sound comes through rear or center chans though. Im wondering if it could be the chip by the light that says CRYSTAL CS4226-KQ and how can I test it and what is needed. I am also not sure how you find part #s.I would apreciate any info any one would have about this problem or the system,if it is worth fixing etc... Tanks for your time.

Check the solder connections on the seven voltage regulators found in the center of the receiver on the heat sink from front to back (not the amp board) they are on the main board. The green light on the DSP board (back right side) is an error light. You can reset the receiver by pushing power then stadium then night then dsp off then club after unplugging the receiver and plugging it back in.

Hope this helps,

When i unplug my rca rt2250 home theater system. the green light comes on on the right side. then goes off. everything works good after that speakers sound good. but once in a while that green light comes...


this is the amp IC and while unplugging and plugging it in again helps reset the IC for a little while , it will eventually completely quit and will need replaced
make sure that none of the speaker wires(bare wires) are touching or look like they might be where they are connected at
also if turning up the volume makes it cut out or sound bad then this will also indicate a bad amp IC

I have a DVD player, VCR player, TV all attached to an RCA RT2250 audio/video receiver. All was just fine until 2 days ago when the DVD player would no longer give sound and icons of the speaker system...


It's possibly only needs soldering of the voltage regulators. they are on the main circuit board heat sink (middle of the receiver and can be accessed by the bottom panel.

it sounds like you gonna break the unit eventually:) now seriously, when a problem can be handled by activating physical force, it is probobly related to loose conections or wiring. if you wanna fix it yourself, take it apart and start loking for those kind of things.

Rt2250 rt2500 speaker static noise hum buzz until fully warmed up


It sounds like a capacitor in the power supply is just about to die. With the power disconnected have a look at the large tin can looking gizmos near the power transformer. There could be a couple of them. Leave the unit switched off for a while before going near them they could still pack a splat. Replace them with the same value and make sure they're connected the right way and it should solve your problem. Whilst in there have a good look for any other smaller capacitors which look as if they're getting rounded at the top. Replace them too. Either that or dig deep and buy a new one.
