If your are certain that you have a signal going to the imputs of your amp and you are certain that the speakers are OK and you have not turned the gain control all the way down then that just leaves a fried amp. Good luck.

LED light doesn't light up on JL Audio XD 600/1

It could simply be a faulty or burnt out bulb, just find a small bulb at Ace Hardware or the similar, and replace it.

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.

This is alimentation fault of the amplifier inside the box. Dismount the amplifier block and take a look first if there are some burned pieces. If it seems all ok, better bring it to a electronics/ tv service center.

On my fender blues deluxe, there is a red light which is usually off. I get intermittent loss of sound, and when this happens, the red light comes on. Any ideas what's wrong? Many thanks Brian

Hi.
If the red light is coming from a tube and you notice a loss of sound when it lights up, try reseating the tubes. You have to make sure that the amplifier is cool and is not plugged in to any power source when you do this and you have to be very very careful with the glass tube as well.
If the red light comes from an LED, it may be an indication of a bad wiring. Check if all wires are in good condition and are soldered correctly.
I hope this helps. Thanks. :-)

There is a red light shinig inside my CROWN XLS

Lots of electronics have lights (LEDs) that turn on when they are plugged it. Most people just don't notice them. If it is working properly, then the light is normal.

Rt 202 led light red and no sound

With the system turned off, disconnect the speaker wires from the amplifier. Turn on the system. If the light stays red, then the amplifier has an internal problem. If the light turns green, then your problem is a blown speaker, or a speaker wiring issue.
