Techno Beam Problem

[QUOTE=John Patrick;49251]Hi Guys
I have a Techno, that has no Pan, on closer inspection during a self test, When I tell test to Pan it is rotating the Litho's back and forward, If I unplug the Pan Motor from the Logic Board it is still rotating the Litho.
Any Ideas on what this may be. The Chips are 3773 Type..I have not tried to replace the driver chip yet. But I did Cross Load from another working unit, in case it was firmware or software related, no cigar .

any help will do TY

What's the history of the fixture? This sounds like it may be something as simple as the harness being mis-plugged . . .

What happens if you ask it to rotate the litho wheel?

Everything is plugged correct and everything else functions as normal .OK Chris, so maybe it is something as simple as the Driver chip then, I'll try a swap out and see thanks guys.I'll let you know

OK changed the Driver Chip no cigar....there is some discoloration on a Resistor to the left of the chip..I am tipping it is that

yeah check the p/t wires behind the sled, also make sure that it set to technobeam on the menu there is a technoray/technopro settings that has no pan or tilt.
