BOSS 634UA head unit bazirk

Ok, I have had this head unit for about 9 months. It has worked ok so far. Today however, I put a cd in and after playing the cd for a few minutes the head unit started flipping through all the preamp settings on its own. It then started turning the subwoofer on and off. Then non of the keys would respond to pushing them. I have tried resetting, reloading, removing and reattaching the face plate and nothing will get it to stop. it does it using tuner/usb/aux/cd all the same. Please help, I am very frustrated!!

I have a BOSS BV760B and the unit will not except a cd. Everytime I put a CD in the unit it will only go in so far

The player loading mechanism has failed, this is common, due to the low cost of these players they are not repaired just replaced except under warranty.

I have a boss dvd7500 and it no longer loads dvds

You have a bad CD mech. The fix will cost more than most people would be willing to put in to a Boss product, considering the low retail price.

When boss dictates a letter I can barely hear any sound!

The tape might be getting old, replace it and see what happens.  If it is still acting up, It might be he is not recording properly or the recorder is bad.  Try talking directly into the mic and see if it is better.  If it is, he needs to talk louder or needs to hold it close.

I have not played my electric guitar for months now there is no sound coming through the amp, the amp works ok

probably have active pickups on the guitar.
if there's a plate on the back, get a small phillips screwdriver, take the plate off, and put a new 9 volt battery in.

I unpluged all the wires for one more time and it works again!!!
I think the problem is that one or some wires are damaged because they are pressed between the unit and its case. I also shaked them up and down and for now, it is ok. Try it!!
If this works for more than one day, I' ll let you know...
