Hi - this is my first post.  I just picked up a Sgima SG-32 machine and it works intermittently.  Here are some of the problems/question I have and I wa hoping you all could shed some light

1.  I can turn the machine on in the morning and it will work fine for about 5-10 minutes.  Then all of a sudden it stops and then the deck buttons light, it makes a slight noise and the reels don't spin but seem to have their 'stop' reapplied if you can follow that.  I've downloaded some pics/video.  The links are below

2. I dropped the PCB down just to look at it.  It looks like there is a chip missing and two of the pins have been soldered with a jumper.  Is this OK?  Do I need to install a chip there?  If so, can anyone tell me what chip it is

3.  I'm waiting to hear back from someone on getting an SG-32 manual.  In the meantime does anyone know of another site where I can download the PDF?

4. It looks like the DBV model number is DBV-38...I can't seem to find any mention of that on the net so I don't know what to think.  Seems like it periodically with accept dollar bills after many tries.  I don't have any old 5s, 10s, or 20s so I'll try those when I can find some.  Can I upgrade the DBV on this SG-32 machine??

5.  I can only ever put three coins in the machine no matter how many credits I have (e.g. 0 or 200).  The fourth and subsequent coins just get returned.  Is that normal?

I'm an EM pinball guy so I'm OK with reading schematics/troubleshooting/soldering/etc.  Any help would be appreciated...Thanks!
Jim
