I was given this unit used and have had it for about three years. It has had this problem and seems like it has gotten worse as time goes on. When I turn on the system, it has no regular sound, just buzzing out of the speakers. If I turn it up more, the buzzing gets louder. I can see a green light is on inside the unit towards the back. When the unit warms up fully (about 20-25 minutes) then the music starts to come in choppy until it finally is fully warmed up and it works well. When it starts coming in the light flashes, and then when it is working fully, the light is off. It does not matter what type of input I use, it still has the same problem. Also, I noticed that if I set my preset equalizer to flat, then I get regular music out of all speakers except the sub. The sub still has the buzz until the unit warms up. All other equalizer presets result in buzz from all speakers until it fully warms up. Any help would be greatly appreciated.
Put into standby press stadium night DPSoff then club in that order that will restore if u did it right when you turn it back on it will be on turner 87.50 thats all it took 4 mine
hope it works 4 u

When replacing the 2 capacitors, do they have to be 16v??? Cause 35v 6800uf capacitors is all I can find.

Sure, use the 35V caps. Did it fix your unit?

If you want real killer sound get 2 cneter channel speakers with them both parellel abd stack em with rubber feet tops and bottom to stop movement, then get on ebay and get 4 baby adevent and the tweeter updates if they are online. wire them with the standard rca speakers in parallel, then get two 12 car subs from pioneer hard cone type place them in a car slant box and wire parallet, HOLD ON I HAVE FOLKS screaming turn it down unreal for the price and I mean unreal.... then again my parasound 2500u and 4 PIONEER SA9800 amps running via line inputs only and OLD SCHOOL EV's will make you deaf! Oh pleaes remove all items from shelf and keep glass out of the listening area!

I can verify the solution provide by videoguy1742. I had the same problem and replacing the two 6800uf / 16v capacitors fixed the problem and it only cost me $8.00 and two days to find a supplier. Most places like Radio Shack, BestBuy, etc. don't sell anything this big. I reccomend you call your local tv repair shop and ask them for the capacitors. If they don't have them, then ask them for their supplier's phone number. That's how I got mine. Just for the record, every RCA product I've ever bought breaks within 2 years. But they are cheap if you're short on coin. If you've got some extra jingle in your pocket get a Pioneer or JVC.

This problem is CURED simply by replacing 2 capacitors inside on the main board. They are easily identified by a bulge on the top end of the capacitors. The capacitors are located between the heat sinks. The size is 6800uf/16v. I am a RadioShack dealer and sold a few of these in 2000/2001. I bought one for myself. I have repaired only 2 that had the same problem as listed by HAGUC above. They both are working great and for the record. . .are NOT peices of JUNK,. . .hehe. . .they just need a little TLC. Parts available from larger electronics parts houses, not at RadioShack

Same exact thing no solution so... I inserted a screwdriver into the electronics in the unit and put it in audio receiver hell where RCA should have put their defectife product to begin with. :-)

I have the same system with the same exact problem. This unit is a piece of junk and I am certain RCA knows of this problem, after all its posted here 3 different times.
I tossed my unit into the trash where it should have been to begin with. No more RCA anything for this electronics fan.

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.

Hi all! Had the same problem as above. Replaced the caps and now as good as new. Maybe just a helpful hint. Replacement caps should be slightly higher in voltage. I suggest 25Volt up from 16V. This size cap would be stronger and outlast the original size. Still be sure to use 6800uf though.
Hi, I'm really excited by this thread because I have basically the same problem. No sound. No fuses are blown. I know also that this unit has had to be reset a number of times. In fact, I bought the unit, plus 5 speakers for 25 bucks, and after checking the net found out how to reset.
BUT, I'm looking at two very large black capacitors, and don't see and sign of bulging. Do you guys think that I should go ahead and replace them anyway? Btw, I have tested that the S-video output works. I just don't have any sound. Everything else seems fine.
GREAT THREAD!!!
