    your report says it needs repairing, i allready know this, you were to come up with a possible solution.

  • brendand1944 Nov 29, 2008

    still no help can you be more exact, since i see many other reports with the same problem, i assumed you would be able to pin point this problem more accurate.

    I think this solution makes more sense, thank you.

There is a condensor (capicator) in the sub woofer that has to be replaced, the buzzing you hear is displaced eletricity. Open it up and look gor the largest capicator thats the one at fault. Be careful though its a bad shock if you handle it bad please be well inuslated. No its not high enough to cause damages just a bit of pain.

Sorry to tell you the ciruit is fried even if the machine you have even is on just a little like a clock and is not connected to a surge protector lighting can go directly to your electronic and do what has happened to you and that is fry your circuit I suggest if warrenty still is good take back for replacement or repair/ or just buy a new one.. but for future reference use a surge protector and here is a neat article that tells you why you should use one.

http://www.howstuffworks.com/surge-protector.htm


What this should be used for is your "computer,tv, or any other expensive electronics

I would just look at 1/4/5 those seem most important.

    Like I sayed you FRYED your circuit because you left it plugged/in on
    during a storm while it was not connected to a surge protector so
    specifically the high amount of voltage went to the circuit zapped the capacitor... Lighting voltage goes up to like 1 billion and your radios only goes up to maybe about 100V so it ruined it by over charging it.. I'll post more if you want

"loud buzzing starts for a short while and slowly fades" one of the capacitor on the amplifier final section, or preamp had blown and you get a 50 or 60 HZ loud humm that slowly fades as the AMP ICs stabilizes the signal.

Try first the following:

Test a different socket, just in case the socket has lost ground after the power surge.

If that does not work call the service number listed on the owner manual and ask modalities to fix the unit, it should have one year factory warranty on it.

    check your spaker in direct ly with computer or any dvdvcd plasyer.

    if it works fine then no pro in speker.

    also check in woofer then check all connection of cable soldering again if need.

It seems some circuit problem, like some out put capacitors gone weak. check them from a qualified technician.

I just purchased the RCA RT2910 Theater System yesterday. When I hooked everything up, it was all working great. However, tonight when I was turned it on, all of the speakers were acting weird. They would...


What source(s)? Verify the speaker setup with the test tones to prove the hardware is all okay. Then go back and evaluate the conditions that create the problem. It could be an external cause.

Loud Humming


Many times a "humming"sound is caused by bad signal, caused by things like, bad rca cable, bad rca ground from the radio, or even a bad ground in from the amp to the car.. Wiggle your rca cables at the input to the amp, and see if it changes the hum at all.. If not take a short peice of speaker wire, and wrap one side arrounf the outside metal at the end fo the RCA jack, and then touch the other end to ground, and see if that makes the humm go away. If the humm goes away at that point then you need to have your radio replaced, or repaired. if neither of these do anything to the hum then check for tight ground connection to the amp, and to the car..

There could also be a problem with the amp it's self, but this kind of thing is hard to diagnose over the web, so try those things, and let me know what happens..

When I turn my unit on, it will turn itself off in a few second.


have you checked to see if any of your speakers are shorted out? the rt2870does have a self protection system in place such that if theres too much power being drawn from the system or if a short occurs it will shut off. or the switch that powers the sub may have gone bad so try disconnecting the sub and see if that helps. i have the same system and i had the same problem and i had to replace the onboard sub-woofer power switch.

You might have a bunch of bees living inside the sub?
You have a bad set of Audio output IC's for the sub. There is two of them. TDA7293 REPLACE BOTH!!!
There is 4 on one side of board,and 2 on other "also 1 small one" The the two are for the sub,the other 4 are for the main speakers/surround. They sell on Ebay for $6-10 each or a kit of all 6 for $25.
