Sanyo Monitor "Drooping" Issues for DK and DKJR

I recently bought a DKJR Cab and an extra DK board. I noticed a couple weeks after I brought it home the monitor has been acting up by "drooping" on the left side of the screen when I plug the machine in. It does it for both DK and DKJR boards, so it must be a monitor issue. The guy I bought the machine from said that monitor recently had been "capped". It seems to take the monitor maybe 1/2 to 1 hour to slowly get back to normal (see the last picture). Although normal still has a little "droop", but going in the opposite direction. I don't mind this so much since I can still play. Its just that I think this problem is getting worse and worse as time goes on. Do you think there is an adjustment I can mess with to fix this or do you think the monitor needs to be recapped again? I don't know much about capping and such...I am pretty much a newbie when it comes to this stuff, but am willing to learn. Thanks for any advice.

Sorry the pictures aren't the best quality, I got tired of fiddling with the million different settings on the camera. But I think they get the point across.

Try adjust VR451 - Horizontal Hold - in the center of the chassis...

I installed a Bob Roberts standard cap kit on mine, when I first got it to fix a screen fold. Some cap kits do not include every cap on the board. I noticed that although the cap kit fixed the screen fold, that an area of overscan that's usually off screen and black was drooping. It was off screen and didn't affect any of the playable area, but when I was adjusting the pot for width I noticed it was there. It also affected the far left side of my screen too.

When I went back to fix another problem, I decided to buy the remaining caps that weren't included in Bob's kit (even the C606), and when I fired it back up the droop was gone. I know yours affects the gameplay area, but it's possible that not all the caps were replaced on the machine. If you feel like it, I'd pull the monitor and check for new caps, and make a note of any original Sanyos. Anyway it's just a thought- if what Mod says doesn't work.
 
adjust one of the pots, like mentioned above. if that doesnt fix it then it is a pot problem, and it would be a good idea to replace them.

When I recapped my monitor and replaced the pots on the adjustment board I had the same problem as pictured but it wasnt as extreme. A slight adjustment fixed it right up.
 
I take it back, I didnt look at the jr pictures and it could also be something else than what I mentioned because mine never drooped upward.
 
It is a sync issue, and Mod has given you the answer. You are not going to be able to swap the two boardsets freely without adjusting this monitor.
