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.

Power but no sound

hook up the antenna at the back and try to tune-in to your favorite radio station.
read the description at the back of your rca rt2250, how to connect your antenna.
connect it properly and raise up the antenna, put it where the signal is good.

when it is playing a cd? well I guess your optical lens has a problem.. adjusting the variable resistor at the side of the optical lens (you can find the optical lens inside your unit where the cd/dvd is playing)..
if your using for radio? bad solder is the main problem, and a capacitor is almost going to blow( but it won't blow if it was installed properly). changing it is the best way.

Audio and Video cutout

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.
