Blue powerr light comes on led digital screen with temp and volt meter the fan lights n evrty thing
hooked up my two 18 inch ma audio subs 1100 watts peak 550 rms
no sound or anything thought subs were bad maybe but i hooked my memphis 15,s to it no go and the memphis were playin on another amp as of yesterday so sum thin is wrong with the amp every thing comes on except no sound from the subs

not sure if it is the same as mine but mine had 2 lights behind temp control setting if one is burned out that might be why it is so dim. also my lights were not led they used regular bulbs so when I replaced them I put in led lights I got off e-bay. if the lights are working you likely have a bad connection somewhere you can try hooking a volt meter up one side to the positive on the battery and the other on the negative on the light if that reads good reverse it hook one end to the negative on the battery and the other to the positive on the light and see if it reads good just make sure there is power to the light socket when you test it. if one side is showing low volts that is likely the bad side and you will half to start checking wires on that side
The blue screen means that the back light is on. There is no signal coming to the screen to modulate a picture though. Also since there is no sound it means that the main pc board in the unit is probably bad.
Disconnect the speakers and then try it again...there may be a shorted speaker or wire if the amp comes out of protect after you disconnect the wires...if the amp stays in protect after you disconnect the wires then there is a problem inside the amp with the circuitry and it will need to get serviced by an electronic tech
OK you need a volt meter to check the voltage output of your power pack as two things cause this now enough power out the pack to run your unit or the unit has a short both problems will unlight the light so you need to know if the power supply is working right first as it should say like 120 volts AC in and 12 volts DC 1000 ma out so you will need to mesure this with a volt meter. this is a common problem loading the load of the curcuit as in your TV is mor the the power pack is giving out thus shorting out the power pack of any voltage present, as the little LED light your seeing only takes 5 volts at very ittle current to light and dose not repersent the total voltage output of the power pack itself
Have you taken a VOM (Volt-Ohm Meter) and checked to see that the "two wires" of which you speak actually have 110-120VAC on them?
I bet they don't and I bet they don't because "up top" (where the connections in from the ceiling box, the BLUE wire (might be brown on some fans) is not hooked up. Unless you have separate switches at the wall, the blue and black wires coming out of the fan must be combined and hooked to the BLACK wire coming out of the ceiling box. White (neutral) goes to white, and green goes to ground.
Good luck, and always OBSERVE practicable safety precautions.
If there is no protection light on, be sure the input is on. Some head units need to be turned on manually (factory set to OFF).
Verify the subwoofers are wired properly.
A list of your components would help to solve your problem.
If it is new, it should still be under warranty - worst case scenario output transistor(s) blown, or power supply bad.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
Turn the system off and disconnect the speakers. Turn the system on. If the amp still goes into protection mode with no speakers connected, then most likely the output transistors are bad. If the protection light is off, hook up one sub at a time until you find the one that is causing the problem
Check the fuse on the amplifier; if it's good, then you need a multimeter or voltmeter for further testing. With the meter's black probe on your amp's ground terminal and the radio turned on, both the power and the remote terminals should test at about 12 volts. If neither terminal shows voltage, you may have a problem with your ground connection; if both do, there's a problem with the amp.
