Well that leaves 2 mor parts the transmit final and the current resistor these have straight 12 volts applied when the radio is turned on . if you look at the final it will be burnt or blown apart on the heat sink. replace them and you shoul be up and talking again.

Full electrical power loss to everything.


Were the cables accidently hooked up backwards ? The main fuse at the fuse block may have blown. Check where your positive cable hooks at the main fuse block and there should be a fuse rated over 100 amps for the fuse block feed.

Sound but no picture


Hook up the composite cables that come with the unit. Turn the TV on to the correct input. Turn the PS3 on using the power button on the unit. When you press the button continue holding the button until you hear a second beep....about five seconds. That should set the PS3 back to the factory output. If that corrects the problem you can set the PS3 to use whichever cable you want via the XMB.

NO sound through the AMP even though the power light comes on


Not a fuse. First thing, to check your speaker (amp unplugged, of course), touch the + and - speaker connections to a 9V battery. If you don't hear a pop sound then your speaker is blown. Thus, no output sound. If speaker is OK, then the output IC is your problem.

My auio just doesnt work.


This sounds as if the output amplifier has failed.
Professional repair is necessary.
To check the rest of the radio is functioning properly, use the low level outputs (RCA) to an amplifier.
If you have sound, the internal amplifier is blown.
The repair shop you take it to should be able to bench test it for a nominal fee that usually comes off the repair bill.

Amp gets power but doesnt send anything through speaker wire


There are several things that could cause this that i know of, bad ground not being one of them.
A bad ground terminal should cause a noticeable distortion in sound and cause the amplifier to turn on and off.
If you are getting power and no sound, the first and easiest thing i would check is your RCA wires. Replace them with known good wires.
If that does not work, are you positive the speakers you have hooked up to your amplifier are not blown?
If available, use a DVOM to check resistances on the coils on your speakers. An open lead reading indicates a blown voice coil.
Also make sure that your speakers are each hooked up to a positive and negative terminal, as some amplifiers have two positives next to each other and two negatives, while others go + - + -.
Your amplifier could also have bad input or outputs, but i would try these other easy fixes before resorting to buying a replacement amplifier.
The only other cause to my knowledge would be bad RCA outputs on your head unit.
If possible try with a head unit you know the outputs work on.

Hopefully one of these suggestions solves your problem.

On and off


Hi.
Take the input leads out of the amplifier for a start, but leave the power and remote cables connected.
See if it still turns on and off. If still faulty, you have probably blown a power transistor inside and the amp is shutting down when the output rises each time. It will almost certainly need looking at. Also make sure you are running into the correct impedance load. If you have hooked up too many speakers you will cause damage.

1st thing I would try is to connect a different speaker to right output...if it works, that eliminates speaker problem. Then swap red and white audio input cables and hook them up backwards- connect red cable to white on both ends, and white to red...cable could be bad internally. Also try hooking another source to inputs, could be blown channel.

No sound


You most likly have the Data cable in one the other or both plugged into the wrong side, this just happened to me the other day with some Pioneer stuff and I had plugged the input outputs backwards. Everything came up as far as sources showing but now sound. That should fix you up Good luck
