Posted: Mon Aug 12, 2013 9:08 pm Post subject: MS2000 DSP Chip replaced |
|
|
Have 2 MS2000 Synths that I am trying to repair, have installed the DSP Chip to both units, I am however getting a "DSP Dram error 4001ff" on one of them when I do the test the Patch's change properly now though and I can hear them but some of the patches sound a bit distorted but not all of them?
The other MS2000 that I installed the DSP Chip to seems to now play all the patches properly I can hear them loud and clear although when I run the self test I get "Midi Loop Check Timeout Err"
Is there anyone on the forum that might be able to help me with these problems? |

Well it turns out that the problem with the Midi loop on the MS2000 was simply because I didn't have a Midi cable looping from the in out ports, thanks to Scott Hamblin for solving that one for me, so its just the Dram error on the other MS2000 that I need to track down? |

Second update the MS2000 with the Dram error turned out to be a bad DSP chip, installed new one and now works perfectly. |

With a great deal of patience and soldering skills lol, it was trial and error to be honest made a few mistakes on the first MS2000 I did but corrected the mistakes and everything worked perfectly, this isn't a casual soldering job though I used a USB Microscope to get close into the soldering points on the DSP Chip this allowed me to see the shorts, I used soldering paste and an dedicated but cheap Chinese Hot Air Soldering Iron to solder the DSP chip to the board, I also used Chip Quick to remove the DSP chip. |
