Video fuzzy and dark after composite mod

[SumnerS]

Hi everyone. I recently performed the composite mod available from Vintagegamingandmore.com and I'm getting bands of fuzziness that scroll up the screen and it is very dark. My VCS is a light sixxer, for good measure and maintenance I installed the refresher kit from Console5 which included some new capacitors as well as a new regulator and power jack. When I was just using RF to my tv with the coax adapter the image was crisp and bright. 

 

I am looking for any advice on what I can do to remedy the situation. I've already gone through the other threads on this forum with similar issues brightness/composite mod/fuzziness and I am wondering if changing the resistors on the mod board itself might help? Any advice would be greatly appreciated. I have attached a picture of the mod board in question.

Show us the underside and solder joints of the PCB. Also you could measure continuity and show us what the attachment points on the VCS PCB look like. Did you remove any components for the mod?

Also did your mod require you to solder a 75ohm resistor on the composite jack between the center video out wire and ground on the jack?

 

Do you still have the RF in place or did you remove it from the system?

I had the same issues when I did a composite mod.  I tried removing one, the other, and both resistors and could get it to either be too dark or too bright.  I eventually ended up replacing the resistors with tiny potentiometers to get a resistance level that brought the brightness to a good level on my TV.  Later though I found out that the image looked different on different TVs so you may want to try that first.

Scrolling bands of fuzziness.... did you maybe miss removing the audio transistor?
