Faulty Mpc2000 Screen

My MPC2000 screen has loads of "dead" lines in it.. the backlight still works. Has anyone else had this problem? is it fixable and does anyone know where to get a replacement screen if thats whats needed?

Any help greatly appreciated..

yep after a long time the screens get that way.

check ebay for replacements... the same screen works in the 2000 and the 2000xl. they cost around $300

and use the search feature for any other questions... because for sure there is already a dozen threads related to it.

when i bought my mpc off ebay it was a 2000xl bought it around 2 yrs ago it came in like brand new condition

Cheers for your help.

hey man

i emailed mpc stuff and asked if they're working on a replacement because they had the power to engineer the pad sensors. I figured they'd probably be able to make screens and also asked if the price was going to be less than 300 since someone mentioned that a lot of the users bought their 2000(xl)s for a few hundred more than the price of a new screen which is just crazy to me.


here's his response!

Yes we are working on alternative and hopefully the price point will be closer to 100-200.

Please let us know if you need anything else or if we can be of any help to you.

Best Regards,

About this display and it´s problems

First of all, if these things all talked about before in some thread, please give link to that.

Is anyone invented what is the reason for this "line problem"? dirt, air or something getting inside of the display element. in some simple LCD´s there is some Zebra conductors (Elastic "worm" made of insulating material with conductive stripes), which get some oxide and loose it´s conductivity. With cleaning it´s possible to get display working again. I don´t know if this construction used in this display type.

second: Is controller type of the display some widely known or is it dedicated specially only for this AKAI use?
example: Synths/modules/effects + many other electronics use these (Hitachi?) based text-LCD´s and if you broke one you can buy new/compatible from almost every market which sells electronic components. Or rip down from some old scrap.

Is it same with these Akai displays? Is the control based some well known LCD-controller chip. So if display broke down, i search some matrix display based with same controller and has enough matrix points in screen, i can get display working. Software may need some fixing, but that shouldn´t be impossible to do.

I don´t care if my MPC is looking ugly (then it´s in line with me) when it´s working.

I have classic and XL. XL´s display is changed not long ago.(Reason wasn´t this line problem. Previous owner was fall the bookshelf to the MPC, so top cover is little bit crushed, display housing is broken, BUT it works)
More worried i´m about my classic, which i bought used from Ebay and i can´t say about operating hours of it

though it's not a proven fact but it is somewhat known in the MPC community not to leave your MPC "screen" on for an extended time... I'm talking about a couple of days to weeks.

I turn my XL off after ever session. it stays on at the most 6-9 hours. 9 years later and the screen is perfect... touch wood.

The heat from the FL tubes that light the display wear out the glue in the display and over time the connectors become loose due to constant on/off hot/cold/hot/cold expansion and contraction...thus the connection gets broken and bam dead pixel.
If you you want your screen to last forever disconect the backlight and wait for a solution...or try to do a mod and use LED's which barely emit any heat.

The Roland MC-505 suffered from the same fault but Roland solved this apparently...
Taken from wikipedia

"The size of the LCD screen makes it difficult to read each feature setting, and over time the LCD screen would lose pixels (this does (in some cases) render the screen unreadable). This issue is due to the heat on the LCD screen-PCB board, the lamination between the crystal and the PCB is opening/splitting up from the little heat inside the Roland MC-505 from over time of usages. Roland has fixed this by making a new updated LCD screen component."

I wonder if it is possible to swap the backlight lamp to a backlight foil. Any infos bout the spects of the power that both methods need (use)?

peace
