How do i repair my logitech s-100 speakers

From your question it is understood that the speakers you were using was fully charged and it was working best for 1 hour completely and suddenly it has been stopped and seems to be totally dead. To help you, it is recommended to take the speaker charger and charge the speaker once again and after sometime check if the speaker turns ON working.
If issue persists, it is recommended to replace the speaker if it is in warranty or ask for repairing the speaker.

If there is an ON/OFF switch at the back of your 2.1 speakers, then switch it on. Or is the VOLUME control set at 0? Turn it up a bit.

Or, are the left & right speakers properly hooked to the subwoofer unit?
Please check.

The first thing you could do is trying another charger of the same type, if the battery starts charging you'll only have to get a good charger, if it doesn't, you have a failing charging jack, circuit or battery at portable speakers.

i have this problem toooo

check for individual speaker resistance. or in the dividing network for some burn fuse or coil.

Hi Jamo 1
, go to start menu, control panel, sound. Then here go into the Tabs and select the Headset as Mic and Speakers. Apply, Done !
If after this the issue persist, then I suggest you to call Logitech support to issue a replacement, hardware failures happen and are covered by warranty terms

Unfortunately I have the same problem. As an electronic engineer I suspect that the power supply part of the unit is damaged. I opened up the module (don' t try it, its a little bit tricky since there is a type of glue around the silver bezel, after you remove the 4 screws from the front holes) and did some quick static measurements with a multimeter, so far no luck. Since I am still in warranty I will try to replace the item. Hint: protect your electronic equipment with ups or surge protection devices.

Replace the logic supply board inside by finding someone on ebay with just the controller or take it to a repair shop is the only 2 solutions at this time for you, thanks and good luck..

I am 100% sure the battery is dead.
Opening my mm50 I find that the small 2"X 1/4" battery is attached to the back, very near the charging socket. The battery is connected to the circuit board through a small plug-socket arrangement - no soldering here like iPod. So, it would not be difficult to replace it by a DIY enthusiast. But it would be difficult to find this non-standard replacement battery. Better leave the job to Logitech service, they'd would certainly replace it on charge basis.
