I am no expert on this stuff, but that fader problem looks like a short circuit and the VCI looks like it turns off but is probably going into overload protection! I would recommend you NOT use it until you have it repaired.
I see your issue with getting service. Let me try and offer a couple of suggestions.
If you open up your VCI, and unplug the bad fader, does everything work OK?
If yes, then plug the right fader plug into the left fader. If everything still works OK, then you just have a bad fader, and you can even try cleaning it to see if it helps (look around on this forum for ways to clean a fader).
If you are still having problems after unplugging the right fader or plugging the right fader wires into the left fader, you probably have damage to one of the boards. For this you will have to find which board and replace it or send the whole unit to the closest repair facility (I know this could be difficult but it is your best chance to find the real problem).
use the the crossfader or a tempo fader as a volume fader. I have not touched a crossfader for regular mixing in years(scratching is a different story).
Ok, i will try it asap.
Btw everything worked when i slide that fader up, not lightly, but with some pressure, then fader works and vci is not switching off.
So, i’ll try to open it up, and look for some bad solder points, i’ll def updating this post.
update1:
Weird, i opened it up, and now everything works better than expected.
When i put everything back, its doing that sh*t again, when i make pressure on right fader, but that little knob, when im leaning it to left side it works great. hmm… without putting it back in case it works awesome, in case - not
update2:
i found the problem,
slider from inside is black plastic, and when that little plastic touches top case, it’s starting to send random midi signals/sometimes switching off.

k, i put little piece of carton, it works, but when i tighten the screws its not working, and doing random stuff, when i unleash them little bit, everything works great.
so i think there is some microcrack in graphite plate, best what to do is to change it, maybe someone has one, i can buy it from you, but i need very fast shipping
haha.
