Has anyone seen this symptom before on a 20EZ? It seems like something related to the adjustment pots but I can't adjust it out. The game plays fine and the voltages are good but the screen is wack. Anyone have a source for replacement pots? Before you ask,yes I did see Dokert's flow chart and this symptom is not listed which is why I am posting. A cap kit has not been done nor has the FB been replaced as I just got the game yesterday. Just wanted to rule out having to buy unescessary items.

You know what!! Know that I look at the manual I didn't. I adjusted V-size,V-hold,and H-center and completely forgot about the H-hold being on the chassis as I have never had to adjust it on any of my nintendo's in the past. I'll try adjusting that and report back with results. In the mean time, do either of you guys know where to source replacement pots for the size,hold, and center pots? Two of the three feel very loose with almost no resistance. I am also missing red on another Nintendo game as the red pot does not work at all.
 
I usually get my pots from Bob Roberts.
Regarding the monitor with no red.....usually it's something else, other than the color pot. Does the color pot look broken? Maybe a bad driver transistor, or an open color gun inside the tube.

If its not the H-HOLD on the chassis, make sure your sync is going into the monitor correctly. I had this same problem and once it was the H-HOLD pot, and the other time it was I wired the harness wrong....
