Question about Koss KS3102 System

2 Answers

Koss ks3102 hts turns on but no sound

Hi, I've had a KS3102 home theater system for about a year now. All of a sudden, the thing stopped making any noise. It turns on, reads cds/dvds, and can switch btw tuner stations, but the no sound is made at all. I tried plugging speakers I knew worked into the receiver, and it still made no noise. I've also tried to reset the AV inputs as sugg. by another q earlier, but I do not have a digital option, only analog, coax, and optical. Can anyone please help!?!?

I had the same problem. For about 4 months I could hear it going bad...it would take more and more time to "warm up" and eventually no matter what sequence of switch clicks I made it would no longer have audio. I lucked out and bought two of these when they were on sale so I had a good way to swap around parts. I switched power boards and found that to be the problem. I found that the 5Volt pin did not have a good 5volts, but instead had about 3 or so volts. the first thing behid the +5V pin is a diode, I noticed that I had 5V on the other side of the diode, so I bypassed it (shorted it) and now the system works fine. Although eventually i will determine what value that diode was and replace it properly. If anyone knows the value of that diode let me know..thx

cd's use a different laser than dvd's when playing. You would need to have the optical pickup replaced.

My bose lifestyle 48 system suddenly stopped playing new DVDs...is there a problem with the head..I bought it only in 2008


is the discs just spinning and then stopping when you put them in the drive?
there may be a chance that the lens might just needs cleaned. suggest a dvd lens cleaner but on the down side there is a strong possibility it may be a faulty lens. dvd players aren't built to last.
always clean the dvd player from dust and keep in an open space.

Philips lx9000r 25S ome theater system Has suddenly stopped playing DVDs from Region 2 (no disc error) It will play DVDs from region 0 and CDs. Do not know access code, so cannot follow manual to change...


The Access Code is 0000 as default unless it's been changed

I think you'll find if it's not playing Region 2 DVDs that it's the same old Philips fault in that the laser has gone / is going.

First of all,if you are using rental dvds, there might be scratch which your dvd player might have an issue to read it;however,if you have tried many dvds in this player and you are having this issue, it is time to move on to another dvd player.
I recommend a Pioneer dvd player.
