Usual problem is unit hasn't been put into sound activation mode. Make sure the display says:

"SOUn" and select the "on" in that mode.

    wot ! yes it is where can i get a new part

    If the optocoupler has been damaged, take the number that is marked and search at

    The part MAY be surface mounted and it takes a bit of skill and care to replace it. The parts ae small and it is easy to install some backwards.

    Before you replace it however, do check the wiring of the DMX connectors. Some of the stuff coming through has not been tested and I have seen wires reversed... compare wiring to a working unit. Also sometimes the wires break. The boards that are mounted with the connector leads directly attached to the board OFTEN have broken solder at those points... resolder suspicious joints.

Appears that the 3.5MM input jack (for my ipod) is loose/broken. How to replace it?

to do that you'd actually have to disassemble the unit. ( start by removeing scews on the bottom ) and dropping out the pc boards that hold the jack or are in the way of the pcb with the jack on it. at which you'd just have to un-solder old jack and install replacement and reassemble and your done. you cann call american audio to find distributers of their parts.

I have an American DJ Hyper Gem LED light and have used it at 4-5 dances...its okay in small halls, but I have a friend that also bought one and his is super bright and throws the effect far, mine does...

Uncover it... you will probably find that some of the LED's are not lighting. OFTEN soldering on circuit boards OR a bad LED in a string kills several like Christmas strings. More than this you need to be somewaht adept at electronics to repair it.

Hi there, I have an american DJ Dekker LED. I plugged it in and put it into Sound active / sound to light mode. I'm getting response to sound because I can hear and see the fan inside the unit...

I have OFTEN found that a cable has come loose. Open the unit and look for such a situation. Also make sure the motion (probably a disc) is working/rotating since with high power LED devices, they have interlocks for safety to keep beams moving.

It sounds like you need to take it to a tech. Try a TV repairman rather than a music shop for this, should be cheaper and they will still understand how it works.

I am having trouble running an american dj quad gem in dmx mode. I have other lights that are working fine.

If by chance teh light is on the end of a long DMX cable run, read about putting a terminating resistor at the end of the chain. You say you are having "trouble"... that doesn't tell us anything that we could help you with.
