Guys : I have A version 5 that i put a crystal chip in, turns out after install i get no disk spin, it tries about 5 times then quits. I then checked the fuses , which all are ok. I then pulled mod chip out, i still have no spin.
Next i checked each solder point for shorts /bobs etc. all look fine .
I am now thinking of swaping laser units, but the only one i have to swap with is a version 7, is it ok to swap the two ????
also after this i am at a loss at where to look next, if any one can advise please do.
