 |

I've got a brightness flicker with my Sony IFB-FULLHD v2 in combination with the VPH-1270.
It happens only @1080i / 72Hz (upscaled BluRay). Not visible @1080i/50, 60 or 75Hz
It starts at very dark or very bright scenes and stops at scenes with mixed content.
Signalflow: Blu-Ray-Player 1080p/24 -> iScan VP50 1080i/72 -> Sony IFB-FULLHD v2
I've tried to change the sync type on the projector from H/C to SonG. Flicker disappears with SonG but picture is very distorted then (wrong colours, dark honizontal bands...).
Anyone an idea?
Cheers
Andreas

Problem is solved and it WAS NOT the Moome-Card. It was the PJ itself.
On the BB-Board IC 410 (4558) was slightly defect. So it produced a flicker on green and red.
Interchanging it with IC411 (Blue Channel) moved to problem to a blue flicker.
I have now temporarily replaced both with TL072 which works fine...
Cheers
Andreas
P.S. @ Curt: still like your G90 offer
