HELP with Frozen screen issues

Went to the studio today and was going to lay down some tracks pushed the power on my MPC4000,and all i got was the mpc4000 logo, the fan and LCD lights for the different buttoms work. But cant get to the main screen. Im thinking that the hard drive is freezing up on me. Is there anybody out there who can please help me with this major issue.

Hey! got the same problem...stay on the logo screen after power up the 4000 it did work today after let go running for a while but still do the samething each time i power up the akai or if it work it will bug while workin on it makin beats...need to what's the problem...pleease someone help

Yeah i tried replacing the HDD and the RAM in it and it still does the same so i just took it to a shop. Im thinking that it has something to do with the CD-ROM drive. But i will let you know what they found when i get my back.

alright no problem... i wonder if it a problem with the 1.71 version...anyway ill be waiting for ur reply

Yo man, when you turn on your 4K does the CD-Rom orangeish color or is it green. Cus im thinking that if its a orangeish color that means that the motherboard isnt reading the cd-rom drive and freezes at that point.

hey! there's nothing no lights...seems not to work...ill try to unplug it...did u get urz back from the store ? does it work ?

Naw i didn't get mine back yet, but as soon as they get in touch with me i will let you know. My lights on mine came on i just cant remember if the CD-Rom drive is suppose to be green or orange.

anyone here can help with this problem...i try to load previous version doesnt work neither

Yeah i found out that it was the CPU but you know they have two CPUs. So go to www.mpcstuff.com and you can get both for like 300.00. Or you can try to pin point it and just get one of them. I think its better to get both replaced that way you dont have to worry about the other one going out.

Really that was the problem...daaam did they change both cpu's for u ?

Well yeah they changed both for me.

hey me again do u know the name of those pieces on mpc-stuff not sure
- PCB, I/O Assembly - MPC4000 ??
- PCB, ADDA Assembly - MPC4000 ??
