RGB / SCART to YUV / Component - pot / knob / resistor / screw adjustment & troubleshootin
I just picked up one of those RGB to component boxes and it's pretty neat. Mine is the cys 2100 / cvs 287 clones (the one with the yellow knobs / resistors inside) and I was wondering if anyone has any documentation or knowledge of what each specific resistor does?
As with most folks, I had to open mine up and twiddle the screws before it looked right. Mine had a slight (but definite) green tint to it. It looks really good now, but I was wondering if one of those unknown knobs might help me improve it even more.
The problem I'm having is a small one, but one I wouldn't mind fixing. There's a slight bend sometimes at the top couple inches of the screen (just where the score is but no further...doesn't touch life bars or counters) that leans to the right and sometimes leaves a tiny gap at the top left of the picture. I don't really notice while playing but I'm big on tweaking so I figured I'd try to figure it out anyway.
Another issue I'm having is screen rolling during bright flashes. I know this would normally require a mod to fix, but I'm hoping one of the knobs is the magic flashy thingy fixer?
Lastly, unrelated (or not directly related) to the converter, I've been having issues with interference over component video with both my PC and Neo Geo. It's three or so wide horizontal bands, present only above the top half of the screen (as far as I can tell). You can really only see the static on really dark/black screens, but again I'd like to fix it.
Does this interference sound familiar to anyone? I know often describing the pattern helps more experienced folks identify what the issue is.
Thanks a bunch for reading!
P.S. My TV is a Panasonic Viera 50U50 plasma, so any of you Viera owners thinking about getting the converter, I haven't heard a single story of a 2012 model (or any model really) not displaying 240p video. I can't wait to hook this box up to one of my old CRTs though.
