I need user manual for jwin jx cd 3250 - Jwin Audio Players & Recorders

There isn't one. This is disposable throw-away junk made in China for 400 Rupees. As I told you, there is only pictures and a review. Take it to your local street market electronics vendor and ask him to fix it.

You must set the clock first. I think that is done by pressing the memory button a few times. It doesn't matter what time you set, as long as the clock is set. Good luck.

Unless this is an expensive machine replace it. There will most definately be an internal problem. It will most likely cost you most just to have the machine taken apart and inspected then it would cost to replace. Sorry...

My jwin jx-mp101blk quit when I deleted the folders in it to make room for saving stuff. It still works as a memory stick, but won't play. What are the needed files?

The laser is damaged or dirty. Try gently swabbing the lens with rubbing alcohol and drying with canned air. If this fails the laser is damaged and unrepairable.
