|
|
Hi,
I tried to start the Barco again after a few months of inactivity, but now there is no picture at all and no possible displayed menu. All leds are green on the G2 board, no red light near the EHT/Quad (the 2A fuse is ok), and the following red leds are on: standby power, main power, processors cycle (flickering) and match block.
I tried another G2 board and another SMPS board, but the problem is still there.
Thanks for your help.

Can you take out the bottom board of the machine and take a photo? There should be three boards inside.

Okay, the board in the red circle needs to be checked. If it cannot be repaired, it needs to be replaced with another good board.

It looks like the Convergence Driver module R762518. I'll see if I have one spare.

I have a spare one (R762512) but without the sub-board xxx2819. What should I do? Remove the current one and put it on the spare one or leave the cables unplugged corresponding to this sub-board on the spare one?

Can you confirm that the HV quadrupler and HV splitter are good?
