Question about Koss KS4102 System
All KOSS unit i encountered are power amp ICs problem, might be yours. usually what comes first dead is the subwoofer channel. try, take that IC off first, and if it doesnt work, look for 10ohm resistor along the supply line going to the IC. to know where to find the supply pins, download the IC specs on the web such as http://alldatasheet.com/. be careful when removing the IC, this is not an easy job as I handled it. The IC is under the heatsink. once you found the bad IC, the unit will on except that channel you have pulled the part off. its a surface mount IC, if your not use to solder components such as 0402 sizes, i would suggest to have it repaired on technician. hope this help.
