No sound at all


Run through your menu settings to see what should be working, and not muted or in functions not being used. Otherwise have it checked by a technician, it may a power supply out or a bad digital sound processor board. Also check your speaker cords, they may be shorting, putting your unit in output shutdown protection.

Hoooking up surround sounds with optical cable surround system is RT2280 AHHH please help my husband is driving me crazy to get it fixed and he cannot figure it out. Superbowl must be in surround sou


Make sure the digital setting (optical/coaxialor analog)is correct.

If youre connection is differet from default setting
1.select the source
2.press function
3.rotate multi jog to toggle among optical/coaxil/analog to match
yuor connection.
your selection will be stored automatically.
every time you press the source button the input setting(dvd/opti)
will be show on display.

No sound from tv, dvd, cable. Speaker test does work. Sound stopped suddenly when channel was changed.


What does this mean: "when channel was changed"? TV channel?? Would that mean a remote command was issued? How about FM (no external cabling)?

I have an RCA RT2280 Home theater system that hasn't worked properly for years. I put the system away in it's box for about 3-4 years and decided to give it a try. To my suprise the tuner was working...


Could be a bad connection on a voltage regulator. (most likely on a 15v line) And check for a bad capicator (one of the larger ones) 4700uf 16v I think. The cap may have vented or the top may have domed.

It is repairable, Parts and labor around $75-100.

I have RT2280. Audio levels used to be 1-50, now


Sounds to me as if someone may have gotten into the menu to adjust the individual levels of each loudspeaker and cranked some of them way up. As to why the "main" volume level goes from1-20 now as apposed to 1-50, you got me there...

Is there a reset button or equivalent on the remote or the unit? Try that. Try unplugging the unit for 15 minutes...

Here's the owner's manual:

RCA 2280 Optical Input w/PS3


The only optical option is through the satalite function. After I hooked up my xbox 360 with optical audio, I pushed the SAT button on the front of the RCA receiver then turned the multi jog wheel until it read "optical" out came surround sound. I hope this helps you.

Rt2280 no power up, no display, standby light works


Might be the relay on the power board that stands up just behind the big transformer. I has a complete no power also, I shorted out the relay legs on the black one, it started to work again. I will probably replace it, since the problem started by the system shutting off randomly.

RCA RT2280 surround sound mode button wont select 5.1 dolby digital mode.


I had the same problem and this is what I did to fix it. Assuming that all of your equipment is powered on, (tv, blu-ray/dvd, rca receiver) you'll need to go into your dvd players audio menu and select the dolby digital audio.
Once you do this, the digital signal is sent to your receiver from the dvd. The receiver should automatically set itself to the dolby digital preset. If it doesn't, press the surround button until you reach it. I found part of this information here. And the rest was personal experience.
Also, it depends on if the disc format is in dolby 5.1. I hope this helps you.
