First you need to check the fuse which is right on the inside after you take off the back panel. I suggest you get someone with electronic experience to help you

    if this does not work the caps are blown on the power supply board and the power supply transformer is bad.

I noticed it was 2 red lights inside the amplifier, what does it mean?

The amp has 7 LED's in total 4 whiteLED's provide back lighting
the bi-colour LED white/ amber is the power/standby indicator (amber when amp is in standby mode)
The two red LED's are on the Phono Board and form part of the phono amplification circuit.( D1 & D2)They are NOT fault indicators and should be lit during normal operation.

No power on light

That's interesting.. After researching that model I can tell you that it has an intergrated internal power supply(transformer) which does contain a fuse. It is located where your power cord plugs into, inside the unit, start with that. Was it plugged into a surge protector? When you had the power failure the second time was there a fluctuation of power, ie your lights in your house flickering on or off or increasing, decreasing in brightness? This will help me determine if it's something else. Also be sure to check your power cord, look for any kinks, breaks, chips in insulation. Anyway Good Luck

My fosgate amp was workin an now it wont trun on can u help me out plzzzzz.....thanx for ur time...

First check your fuses, all fuses. Then check to see if it's getting voltage to it, look to see if any of the LEDs are lit up, power, protection (over /under voltage, overload (short)) or none. If the power LED is lit & no others then check your RCAs coming into the amp by replacing them or using a multimeter set to ohms to make sure they are not loosing a connection due to wire breakage inside the casing. Cheap RCA's will easily disconnect inside the plug just from twisting them. If they are good and are not disconnected from the head unit, then check your speakers for damaged coils or loose wires, who knows they may have fallen off? If your amp has more than just power LED lit then you may have a short in your speakers or wiring disconnect the wires to see if the protection LED goes away. if not and it's still lit then repair the amp. If there are no LEDs lit at all, check your remote turn on wire from your head unit to make sure it sends out a 12 volt signal to the amp. You can also jumper a wire from the 12v battery connection over to the remote turn on connection to see if it will power up. If not then check power wires and connections, fuses, Battery , alternator, voltage regulator, etc.. any thing that has to do with your cars electrical system may have fried from the current draw by your amp.

Speakers won't power on when plugged in

firstly check your power cable by moving the wire in various directions while it is plugged in ac outlet and powered on, if it lit up the standby power LED then the prob lies on the power cable. If not, try opening the speaker system box itself (be sure to unplugged the power cable before opening the box), then visually check inside for the little cylindrical glass type tube(if the circuitry still uses this kind of fuse) if it is burnt-out.
Hope this help pal...

HP a1210n power LED on back flashes and unable to boot up computer. Recently installed memory upgrade and had to unplug 20+4 plug from motherboard and plug back in once the sink was charged up. Worked...

Try disconnecting the plug form the motherboard. If the LED stays lit, you may have a problem with something you touched inside. But, if the LED does not come on at all with nothing connected, the power supply is dead. 300W should be enough to run your computer, unless you have multiple graphics processors or too many peripherals, but just upgrading memory shouldn't make a difference. Make sure the memory is seated correctly, maybe try taking them out and putting back in, or check to see if maybe you loosened something inside while you were in there.

My computer won't boot up or something; no power led lit.

Seems to me your Ram module connector is dirty. Clean its edge connector with a soft eraser. Or if it can, transfer it to the next ram bank. Or your memory module is already dead.

Power Never Comes on

that remote wire has to be hooked up to the power or the radio power antenna wire which will switch the remote wire on when the radio is turned on, so that remote wire really should be hooked to the radio wire that gets power when the radio is turned on , thats why the sub is not turning on

Kenmore HE4 no power to control, no sound, but the drum light bulb on when door opened

Another post reported replacing the power cord. I am trying to determine if this is a factory defect. Check the power at the power cord connections inside the dryer. You could have lost power on one leg and the other 120 volt leg is letting the light work. Let me know what the model and serial number is.

What voltage required to power a sony subwoofer


I just got one of these units, the SONY SS-WG990.
The RCA cable is direct conection to the speaker.
It requires external AMP.
The other cable is just for the system switch and LED.
If you just have this unit, all you need is an AMP to
feed it.
