TG16 RGB mod, blurry color bleeding
« on: June 01, 2013, 08:16:13 PM »
I recently RGB modded my TG16.
I used the RGB amp here -> http://www.gamesx.com/grafx/pce_rgb.jpg
I tried to hook it up to my Sony PVM 2950Q with the amped pure sync as in the diagram.  However, it would not sync properly.  So I switched the sync part of the amp to just use an lm1881n instead and fed it composite and extracted the sync from that. That gave me a fairly nice synced image.
However, there is one annoying problem, there is color bleeding like seen below.
Anyone know what would cause this?

PVMs can use composite video as sync.  Try taking the LM1881 out of the equation and see what happens.  Also, that picture looks like the image is too bright.

The PVM-2950Q doesn't accept composite as sync.  I always have my consoles output raw sync.   When I try the tg16 with composite as sync I just get a black screen.
I do have a PVM-2030, which likes composite as sync. I'll have to give that a try to see if I get the same problems.
The brightness of the screenshot is just the exposure settings on the camera.

Yeah, tried my PVM-2030. I don't get any problems there both with regular composite as sync and the output from the lm1881n.
