I have a NSS that I got off of the bay, and I'm not getting a picture. So I searched the forum for video mod on this board. And I noticed it's already been done. So I checked some voltages and I'm missing my 12volts after R101 which looks like it's missing. I need the value of R101 (parts side of Board), I'll post a pic soon. Thanks: Long Hair
 
I don't need the r101 value now. That's how the mod works. So now I need to know where and why the voltage isn't going past this mod? I have voltage on the left side of r101, but nothing on the right side. I think the right side run's the audio and video. If someone knows why the voltage my be gone and how to fix, I'm all ears. Schematics would help I'm sure.

Found the problem. It was the 10ohm resistor from the mod.It's all good now.
The colors are pushing a little bit, maybe the monitor needs adjusted or the game board needs the caps replaced.

I decided to replace the 10ohm resistor with a voltage regulator, because it was feeding the chip's 12volts. I noticed at the boot screen were it Display's Nintendo the color's are not distorted when I give it 9volts. But when you start Super Mario you get a washed out picture. Bumping the voltage up to 10volts or more gets the picture back, but all the colors are pushing to hard. Anyone have and idea what the issue might be? Thanks Long Hair.
