Two problems in one. Firstly, the control station sometimes won't turn on - even though the unit is powered (judging from the red standby-light). Second, the control station has a tendency to, every once in a while, "hang" in one of the menu's, e.g. when regulating subwoofer/sattelite volume with the "level" button on the panel.

Is there a laptop near by? Some (most older) laptops, can send out infra red codes. Used for infra red communication with hardware. I once was shocked when my lights went on and of without any cause. Till I found my very old laptop did so, when I used certain buttons.
Perhaps even another remote control is sometimes giving the right code, just to switch on?
The Acoustic Authority A-3780 speaker system was an awesome unit blowing away all other competitors in it's price range. One would pay four or five times more to get similar results. Some owners have even used the system for Karaoke and keyboards on stage (very demanding and not recommended) in small venues. That's the good news.
The bad news is that the parts used failed often, especially in the remote control. But if you own one, here's a few general electronic repair solutions to help keep you up and running.
Problem: Remote won't turn on the speakers.
The power on switch is usually broken. They don't seem to last long. 1 Replace it if you can find one...good luck. 2 Replace with another switch design with a little modification to the remote case. 3 Remove it and resolder wire jumpers where the switch was on the remote board so that the unit is always on unless you unplug it or turn it off using a surge protector. As this system did not have a delay circuit per power on and speakers on it will work the same.
Problem: Scratching noises when changing the volume control on the remote.
Oxidation/wear on the volume potentiometer. Using a electronic contact cleaner will clean it up for awhile. 1 Replacement is best but you probably won't find the part. 2 Keep the remote volume fixed and use the computer volume to adjust.
Problem: Loud buzzing from the speakers. Tests: 1 Do the speakers still play audio even though you hear the buzz? 2 Does the buzz go away and the audio is OK on a headset plugged into the connector on the remote?
If yes then chances are one or both of the large 10,000uf 50v electrolytic capacitors on the main power board in the sub woofer has blown. These are filter capacitors to eliminate AC voltage in the DC. When one fails you can get a loud AC 60 cycle hum at the speakers. Check to see if the capacitors are flat on top. If one or both are bulged upwards then the capacitor has vented the electrolytic fluid and failed. Replace them both even if one failed. They cost $5.00-$20.00 online. You can also find them sometimes in audio power amps/receivers if you have a broken one in the closet.
Problem: No audio, no lighted remote. All connections are correct.
Check all parts on the sub woofer power board for any visual failures. When ceramic capacitors fail they usually blow up. Check resistance on all resistors looking for shorts or opens. Get a DVM with Diode Check (example Fluke 77) and check the diodes. Also check the large power transistors for shorts or opens. Just read the resistance across the transistor pins and see if they all match between each other. The specific value in not important. If one is mostly shorted or open compared to the others then it has failed.
Hello Beerisfood,We are the Canadian distributor of the LightSpeaker. Sometimes very rarely the LightSpeaker may "un-pair" and "re-pairing" the unit to the base is needed. It takes under 10 sec and is very easy to do but must be performed in a specific manner. 1. Power to the LightSpeaker must be off.2. Turn on transmitter (base) 3. Press the "pairing" button on the transmitter (base) -lights will flash on the transmitter, during that time that they flash, turn power "on" to the LightSpeaker. The light on the LightSpeaker should now be green. Youtube has a great video as well on pairing. Type Klipsch LightSpeaker and the first video should walk you through the process. If that does not work contact www.lightspeaker.net as they are the manufacture of this product.(Klipsch was just the US distributor not the manufacture) Hope that helps.
Hi there!, I have read the manual for your system,..and maybe I can offer some solutions....Firstly, I am a musician and have experience with a lot of musical and studio equipment....some may seem simple, but it can bug you for hours or even days.
You must follow some simple troubleshooting steps,...to cancel out the possibilities.
Firstly, turn off your system, and disconnect it from the source,....I am guessing it is a PC. Disconnect ALL connections and then set them up again with the power off. When all speakers and power supply is re-connected, turn on again. Run a speaker check, your system or PC should be able to help you with this. If the speaker is still not working, next, swap the right and left speaker outputs. If the speaker works, then the problem is NOT the speaker ok. If the speaker still does not work, then it is a bad speaker or bad lead to the speaker understand!?
I had the same problem right out of the gate, the volume dial on my control pod for my Companion 5 wasn't working, however, the touch pad and LED worked. I called Bose customer service and was instructed to:
First, unplug the power directly at the back of the woofer while the unit was on;
Next, I was instructed to unplug the control pod, visually inspect for any damage/defect;
Finally, re-seat the control pod on the back of the woofer and then lastly plug the power cable back into the woofer.
I live in the Netherlands and i hear radio from UK, Russia and other languages. It's true it's in evening. Weather here now are rain in thunderstorm, i thought thunderstorms maybe could be the problem. Yesterday evening i heard nothing of the radio station. Hearing that radio staions is against FCC rulles. So it's possible to complain about it to radio stations. Im going to contact Logitecht tmorrow about this problem. I keep you updated.
