So little valid infos or even a picture.....what is a C/R?

I seriously doubt if it is repairable by yourself, and if bits are already missing, the guarantee is shot. Go buy a new one, they are soooo cheap!!

Cap/Resistor I guess.

Try manufacturer for diagram but you'll have better luck winning the lottery. Just put it together and return it.

Your problem is very difficult to troubleshoot because:

1. The description of the problem is very much incomplete. What type of device is it? Where did it come from? Did you purchase it, find it, borrow it?

2. Please spell out all acronyms.

3. Please pay closer attention to your writing. Some sentences make absolutely no sense or are misleading at best.

I would suggest that you restate your problem with these things in mind and I would bet that you might find a solution to your problem.

First things first. If you've opened it already, the warranty's gone. Forget about getting it fixed or replaced. They won't accept it.

Second, a no-name brand manufacturer wants to stay hidden. Why else would you keep your brand name off the item?

Third, I agree with Andy, buy a new one.
