DO NOT LET THIS THREAD DIE! I just got an mpc 2000 for 150 bucks, and it needs a new screen

Testing, testing, 1 - 2 - 3

Pulling too many Amps...... afraid it will cause damage to the PSU

Also.... physically, the LCD Panel PHYSICAL SIZE is correct, but is a greater resolution (Not utilizing all pixels) so display is small and screws with the characters.... BOO....

Again, they didn't stick to spec, and no doubt used some panels they had thinking it would be ok....

Didn't have much time to screw with it, so I'll get back to it soon.

Technically, these work, but they are not right.

I'm afraid to leave it on being there is still a electrical issue, and I'm afraid it will cause damage.

Gonna HAVE TO do more testing with the unit on to figure out why it is drawing... haven't checked specs on all components yet, so not sure where it's coming from, but I'll find it....

yeah for real dude. Im in for one unit.
Question.....would adding a resistor or a really small rheostat to the power source(not the actual power transformer, but where the screen draws its power) maybe help alleviate the Ampere problom? or is it a series circuit?

Its a very complex circuit...

Just finished a session, but need to sleep... Long long day, and have to do it again starting at 8am....

An entire day of mixing... Gets exhausting and my head is like... Just too much for one day.... Ear fatigue....

Not sure where the issue is coming from, but should be easy to find once I can devote. A couple hours...

VERY SENSITIVE TO VOLTAGE SUPPLY ISSUES. once extended the wire to move the transformer a few inches... half as bright.

damn... ya'll got me worried. I haven't messed with my 2KXL in about 4 months since dicking around with my MV. I better make sure my screen is ok. :lol:

Interesting thread. I did some reverse engineering the screens myself and came to the conclusion that they were pretty much impossible to re-spin unless done by the original manufacturer, who said no. The screen is a one-off oddball design that was not used in that style in anything else outside of Akai. So odd that it pretty much left the MPC2k to VGA plans dead in the water.

Dual chip select design is the oddity, but I am sure SMC has figured that out. If not, he is in for a surprise.

Flaw in the PCB

Would love to say it is their fault, but that is not the case. I made a mistake.

I am not an electrical expert... more an Amatuer Guru... I'm actually suprised I got it that close :)

Sent them the correction... but need to wait until my truck sells so I have the funds for the revised screens.

The other issue with the actual LCD panel that was used was their bad, so that doesn't cost me anything, and is now sorted.

Gonna be a minute tho
