PLEASE HELP! MPC 2000 Classic right channel fuzz/static dist

Hey, I'm new on here and I need some help with my MPC 2000 Classic. Recently the right speaker output has failed. Sound still comes out, but it is very distorted. The left channel works fine. The machine powers up and boots up with no problems. When a sound is triggered, the right channel is very distorted and a continuous fuzz is emmitted through that channel. I have swapped out the cables and all of that, but it still does it. It also happens through the headphones. I noticed that when i remove the effects card the continuous fuzz goes away, but the sound still distorts through the right channel. These problems appeared at the same time, so they are definitely related, but for whatever reason, removing the effects card cures the one issue of continuous fuzz. I have made a demonstration video that can be viewed here: http://www.youtube.com/watch?v=KXjKskrE2xI
The only other info that i can add is that i recently replaced the screen with one of the screens that MPC stuff is selling. I don't have the original screen anymore to test with. Any input is greatly appreciated. Thanks!

did you check if everythings still ok in the machine? (ram seated properly, ribbon cables attached well etc)
im not really knowledgeable, but id check that

Thanks! Yeah, i've had the entire thing apart a couple of times...didn't find any loose connections.

I'm afraid that this is really an issue only someone with a deeper knowledge in electronics (and especially music gear or samplers) can solve. It doesn't seem to be one of the usual issues like RAM or volume potentiometer. Its strrange that with the fx board the distortion sound remain all the time and without it its only hearable as long as the sample play.
Have you tried to route the sample thru the FX board only? I mean in the mixer set the sample vol all the way down but send the sample to the FX board. In the FX board settings set the direct signal parameter OFF so only the efffect can be heard.

This might help a bit to locate the problem.

Good luck!
peace

EDIT: I was kind of shocked that you turned on the MPC with the display laying there inside the machine. The video is dark so I didn't really saw if there is something inbetween to avoid shortciruits or contacts. Keep in mind that the lighttubes of the display are powered with high voltage.

Thanks Peterpiper! I havent tried that, but i will. Jeez, i didn't realize that about the screen... ill be sure to be really careful, thanks!
