I plugged my Logitech Z623 (110V) into a 220V output. Made a 'pop' noise and now it doesn't work. What parts need replacing and how would I do this?


Take unit apart an look at power supply. It could be just the solid state fuse popped. Power supplys are not hared to repair, the diodes are about .50 a piece, the caps about $1 a piece or so. Hopefully ot did not reach the speaker, an i doubt it did.

I have just bought Logitech Z623 Speakers and connected with my computer. All Speakers work fine upto certain Volume and Bass level but One of the satellite Speaker ( Mostly Speaker with Volume/Bass...


try swapping the speakers around if the problem still persists either the speaker is faulty or
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
or you might have to clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems
be sure to wear an anti static earth strap before touching anything inside your computer try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your SOUND CARD dust causes static to build up in a computer causing it to overheat any many other problems
other than that you might have a warranty issue
hope this helps

Ive got a 4 way amp the one block of two outlets nos 3 and 4 are working but 1 and 2 arnt?


check the channel mode switch on the amp it goes from 2 - 3 -4 make sure it's on 2 if your only using 2 audio jacks if that don't work check connections directly from that channel to speaker or jacks from player. jacks could be broken on inside if excessive pulling was made during installation if none of those are ur problem get the amp checked out

My amp fell forward and the (knob side) hit the ground. Now there is no sound, but everything lights up.


You have probably broken some of the pots. You will need to take it in to be serviced or if you have experience take the amp apart and take the circuit board out. Examine the solder side where the control pots are. Hopefully you didn't break the pots themselves and the solder joints just need to be redone. Also look for broken traces near the pots. They look like little roads which they are for electrons.If they are broken you can bridge them with short pieces of tinned wire and if the circuit board is cracked it can be Crazy glued. Look for all the broken parts and don't miss any. If the pots are broken, Take the broken ones into an electronics supplier and ask for exact replacements. If its a tube amp look for tubes that are loose in their sockets and broken tubes. Absolutely do not work on the amp with it plugged in to the wall (no power running to it) If its anything worse than that, take it in to be repaired as you need schematics, test equipment and direct replacement parts to do a proper job. Hope this helps.
