Can anyone help me here???

Now THAT! is a good question!

(can't beleive no-one asked me that before)

but thinking about it, I hope they all had their PS2's switched OFF

before adjusting the laser.(no idea what the resistance would be if the unit was switched on????)

(obviously if you use the oscilloscope method, you would need the unit very much switched on and dancing)

Best regards...kev1n~
