You can always shoot some electronic cleaner in them as well. sounds like dial may have bad contact

It doesn't matter which cart I use. Of course, I've checked the batteries, no problems with that either.

edit: Just checked the polarity everywhere, it seems to be OK (except that I forgot to replace one cap). When I turn the contrast dial, sometimes the contrast is table, sometimes it's changing. I guess it would be nice to replace the contrast and volume pots too...?

don't know but I have a similar thing with a stock pocket, do you use the same cart every time you turn it on? For me it happens when ever I switch carts.

[Well, I'm just started out with modding, so go easy on me please :) ]

I'm trying to restore a DMG, preparing it for some mod (want to do screen backlight, prosound, pitch mod later). I recapped it, but something is definitely not OK - when it's turned on, the screen contrast is constantly changing.

Do you have any idea on how to solve this, what to check, etc.?
