Capcom ZN2 Motherboard Video Amp Problem

[chacal231077]

Hi!

I have a problem with contrast amplification on my ZN2 motherboard

Normally I just need to set my screen contrast to 50 percent, but at this setting it's ultra dark.

I have to go up to the maximum contrast setting to get a decent image.

I have already changed the MC44200FT, taken from a Namco System 12 videoboard, but the problem is the same.

Did you have a clue as to what could amplify the contrast on the motherboard ?

I'll show you a video of my problem.
