High frequency noise form my 7.1 surround sound system


Is the microphone live? If so, what you're getting is called "acoustic feedback". Any room sound gets in the mic, gets amplified, comes out the speakers, and then gets picked up by the mic again. Louder and louder until you get to the maximum your system can do.

The solution is to turn it down. . . until it stops.

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 lg lcd mod#lc427d hdtv how do i hook up an rca rt2280 system to it. i have a dvd player hooked up to tv now using hdmi cables, rca av reciever does not have them...


You can check your dvd player for a coaxial or an optical sound output, then you can plug it directly to your receiver. Those two are the best options after HDMI. Another option is A/V RCA type cable, you´ll need 3 stereo A/V wires, in order to connect the 6 channels. Remember to uncheck the HDMI sound output option on the DVD menu.

Have you disconnected all of the speakers and tried? Sounds like there is a short and the amp is going into protect mode.

"Check SPK"


It may have been a bad solder connection on an emitter resistor, now it probably needs output transistors and a resistor or two.

Make sure it's not a speaker disconnect all speakers and power on if it still displays "check spk" it needs service. Est $100 to $140 Total

The side back speakers wont work. i have everything plugged in and when i do the speaker test they dont make noise...


make shure you have the correct polarity ,black negative and red is positive ,also make shure you have enough of the end of speaker wire stripped , if that is all good then remove the speaker from your system and hook it up to a regular stereo so you can test the speaker , if the speaker still does not work then you have internal problems in that speaker , if the speaker does work then you have problems with your sorround channel , if both the rear channels are not working it is highly unlikely that both speakers are defective so you probably want to consult the manufacturers warranty and let them either replace the speaker or speakers or the unit that supplys the power to the speaker , hope this helps you and good luck, glenn

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.

Chk spkr error message


Your problem is the output IC's The case where you say the speakers buzz tells you theres a short in the audio outputs. If your unit didnt shut off, the speakers would fry and the unit would also smoke. These are solid state devices and are soldered in, and are not concidered user serviceable parts, unless you know how to solder and trouble shoot Stereo systems. This is a job for the pro if you want it fixed. Good Luck
