Geoff Are u able to enter service mode by pressing FREEZE & SILENCE button during bootup. Go into service mode & see any bad values like voltage , offsets etc. I am trying to call my freind but same here due to ramadan every one is hard to find :-) Sorry for this. I will try my best. Actually i have given manual to my teacher & he is in UK now.. So dont know when he will be back. Will update u soon. Do let me know if u can enter service mode. regards LAIQ
