I recently shopped out my Demo Man, and have now run into a problem. Upon start up, the CRYOCLAW all it seems to want to do is endlessley turn in a counter-clockwise position. I have taken out the opto-baord and clean with a Q-tip and Alcohol inside. Doesn't seem to help.

1. What can be done to fix this? I have included a picture of the board
2. When I put the board back in, is there a calibration? On the motor, the half-moon rings that read insdide the opto, how should they be lined up? Picture of motor included

Thanks

It won't even go that far. Like I said As soon as you turn the machine on, the claw start spinning in sa counter-clockwise direction the whole time. Won't stop. Have to immediatley shut machine off

Are the optos bad at this point? Where can I get replacement one. I look up the part number stamped on the optos : S-1865 Mexico 9348 and can't seem to find anything

Can anyone else help?

If the Optos work after I test, what else could this possibly be? Sorry to keep asking questions but I would like to know all possibilities as a I have a long weekend and can really devote some time to fixing this.

Thanks for everyones help so far

Just called Marco's they say they don't stock this and have never had it. I even sent him a picture.

I asked about those becuase I found them on the site while I was on the phone with him, he said those are are not the right ones. I don't know if he was absolutley sure or not, but as I have learned in the past

TRUST LTG....He knows what he is doing.

I will do your test first.

OK. Still need help here. The optos check out fine as LTD instructed to test. I also tested all switches in the matrix across and down. They are all OK. Any other advice?

Thanks and

OK. I have replaced those transistors. No dice. I also went as far as plugging in my power driver board from my star trek next Gen. Still does the sane thing. I am at my wits end with this. Please if someone has any other suggestions I would appreciate it. Really appreciate all the help so far. Thanks

Think I have it figured out. The is a bridge driver ice on the DC motor control assembly. The thing reads as open with a volt meter. Don't think it suppose to be that way. A whole board from Marcos runs 50 bucks. I found the bridge driver on mouser for 10 bucks. The initial part number matches which l6203 is but I can't find a part that has both L6203 and the number under it which is L88AP401 does this matter?

Thanks

One tested short but still did not fix. Sorry forgot to put that in last post but still did not fix. My bad. But also discovered that thing on motor board bad.
