Remove off all the speaker connections and connect back one at a time. Check if your speaker wires have grounded or short, test the Sub seperately for any fault. If not connect and power. If you notice any distortion then there is a confirmed fault with your mosfet drivers. Make sure the +B and the ground is good when you test. Also if the signal is not distorted from the head set. Check for signs of over heating, if so there could be deteriorisation of the output drives . You must check the juctions of the mosfets for good values or else replace them. It is most possible that the fault must be in the power output than in the pre amps. So please check this out , get a familiar help if your electronics need updation. Helpful I hope. Good day

You either have a short in your wiring (between the amp and the sub) or have wired the sub(s) at too low of a resistance. If for example you have wired it to 2 ohms, when the amp can only support a 4ohm minimum, the protect light would come on once you tried to turn up the volume a bit. This may happen if you have lost the wiring off one of your subs or one of the voice coils, thereby affecting the total resistance.

Same monitor, same problem!!!


While the unit is attempting to "come ready", disconnect and reconnect the 7 wire blue plug. Some how or another, this disrupts the start up pattern that is failing, and the monitor comes on as normal when reconnected???

Fantom 120GB HARD DRIVE BLINKS RED& BLUE LIGHTS WITH SOUND


Sounds like your drive is trying to recalibrate itself which is what the clicking noise is. This is similar to the post routine for your motherboard when you boot up to ensure everything is operating properly. You indicated the drive may have suffered some physical damage and this is a result of that. Probably a head crash and one of the heads is damaged or the calibration track is damaged. Try switching the heads with another drive of the same model. If it comes up (calibrates) get your data off fast and consider yourself lucky. If it doesn't come up then it is dead. You can call one of the repair services listed on the net or try contacting the manufacturer for their opinion. Good luck, but I think you have a very serious problem.

No reception or sound on rear speakers.


Here's the fix: power off the sub-woofer and wait for 60 secs before powering it on again. My rear receiver works every time now.  I guess the sub-woofer isn't just a dumb speaker; it has some kind of smarts in it too.
Prior to this, I had only tried cycling power to the DVD player itself.  I also re-seated the two, fat cables connected to the junction box. One of them had worked itself slightly loose and the result was completely absent speaker channels.
