When I use single green projectors, the brightness control doesn't work. The blanking is work.
In the projector diode driver is analog, but the Ilda signals arrive the Ilda Balanking / intensity port to diode driver analog input.
I tested the dioda driver and I connect the single green ilda port, the brightness controll is worked perfectly.
Then I measured the FB intensity / Blankink output port voltage. The voltage is 0 or +4.8V. Not regulated. (why?)
When I use the FB3's with RGB projector, the all fuction work perfectly.
Maybe, is the FB3 not know the Intensity / Blanking port? Or the Ilda intensity / Blanking port never add regulate voltage?
What is the normal function?
Thank you,
