I posted in another thread about swapping a Barco 180DVB22 into a Marquee, and had anyone successfully done it. Apparently no one had as I did not hear from anyone.


Today I took the step and inserted the 180DVB22 into my Marquee 8500. I had to make a small mod to the neck board but the pj has been running for a couple of hours and all appears fine.


The mod to put the 180DVB22 into the Marquee required moving the G2 line to pin 6. Pin 6 and 7 on the Marquee NB are tied to ground via a 330K ohm resister. I disconnected one side of the resister and created a connector to slid over pin 6 and attach to the G2 wire. To reinstall a 180DMB22 I just remove the jumper and reattach the resister.


Looks like my 8500 has been resurrected.

Yes please add the note to the infinite wisdom of the board that you must lift ground from pin 6 on a marquee neck board before using barco tubes in it.


I don't think good things would happen if pin 6 was grounded and g2 was shorted to it.

Note: PLEASE REMOVE THE GROUND BEFORE APPLYING POWER. Simply disconnect one end of the resistor and good to go.


Hows that pccinema??

:) That would do it, if the search function worked all the time. I swear there's something wrong with searching here. I know from memory many many thread titles and then I go to search when I need the details and nada...


I think this needs to be linked to the original swap thread.

It's grounded through 330K though. Possibly the worst thing that could happen is you'd lose a night's sleep because you knew you didn't take it out. :)
