Well Jamez sounds like you have eather blown the soeakers or the output IC's inside the unit. If you have a meter you can simply disconnect the speakers and test the resistance of the speakers with an ohm meter. If you dont have an ohm meter then you can connect them up to another stereo or have them and the unit tested at a repair center. Sorry not really any serviceable parts in these systems. Good Luck

Yeppers, when you where changing out those speakers, you shorted them and that in turn blew out the audio output IC inside this unit. This will require you to disassemble the unit, locate the blow output IC abd unsolder it, get a new audio output IC, put some heatsink compound on the back of the new IC, resolder the chip and reasassemble the unit. But before you turn on the unit, double check those speaker wires again to make sure they are not shorted as if they are, even one tiny strand, this unit will blow the IC again. Never work the speaker on any solid state electronic amp when they are plugged in and on. Good Luck

Sounds like the lasers need a POT (potentiometer) adjustment. Tools you will need are a multimeter with Ohms (preferably digital) either a #1 or #00 and #2 philips screwdriver. You will need access to the bottom of the laser. On the units I've worked on the POT faces the back of the unit. It will look like a philips head screw in a square metal casing. You should not need to completely remove the CD tray assembly but you can if you wish though I recommend removing the tray bezel Look for two legs on the side of the POT casing that go to the laser PCB. Measure the resistance across the two legs for an initial reading. On mine it was exactly 1kOhm. Now take the #1 or #00 philip screwdriver and adjust the screw to lower the resistance. POT screws are typically EXTREMELY sensitive so 1/16 of a turn can make a big difference. Start by lowering it by about 20-25%. So if the initial reading was 1kOhm aim for 750-800Ohms and test. You should use several disks for testing. If your unit is capable of CD-R/RW playback then have those available as they are generally more difficult to read. If you have playback gradually increase the resistance 5-10% until the disk is no longer readable or struggles to read. Now lower the resistance again 5-10% and retest. If all works well reassemble and enjoy. It is necessary NOT to lower the resistance too much as it will shorten the life of the laser and if too low could damage the disks. If you must go lower than 25-30% the laser is not worth salvaging. Typically 10-15% is all that is required. If you need more detail I recommend doing a search for 'xbox POT adjustment' as the procedure is essentially the same for all lasers and some xbox sites have good pictures so you can see what your doing before you dive in. Total repair time per unit will be 1/2 - 1hr, mostly spent in all the testing. Hope this helps. Good luck

No sound from stereo


If you can hear a hiss then the spkrs and amp are OK. It sounds like you're not on whichever source you're wanting to hear or it is on mute. Make sure ther is no function enabled that turns the sound off or over-rides it (like a tape monitor or AUX in...).
