how to troubleshoot a DPM 3se?

Post by swatki » Sun Jul 24, 2016 2:53 pm

Hi all,

This is my first time here; I'm hoping someone can help, or point me to helpful information.
I have a DPM 3se that has been in storage for 15-20 years. It doesn't seem to work currently, but I don't know how to troubleshoot or repair it.

When I plug it in and turn it on, the display backlight comes on, and the amber light on the disk drive comes on, but nothing else happens.

When I put a disk in the drive (such as the Setup disk that originally came with the keyboard) the disk drive makes noise that sounds like maybe the disk is spinning (a sort of buzzing whirring noise), but nothing else happens.

Is there any chance that this machine is going to work again? Any suggestions for what I should do to troubleshoot? Thanks for any info!

First, look inside at the battery. Is it all fuzzy and leaky? Ther is a clear residue that leaks from failed batteries and coats the board in that area. Unfortunately the stuff is conductive. It is a major pain to clean, but the folks at Peavey are very good at rebuilding those. As always, if you send them the boards, contact them first.

Other than that, you want to make sure all operating voltages are present in the power supplies inside. I forget how, but there is a reinitialization (restore factory presets) that may help. it is usually a matter of holding two or three buttons down as you power up. See the manual.

Schematics are available from customer service at Peavey.

The Peavey customer support is exceptional! I contacted the parts department today and the staff member there graciously emailed the schematics of the DPM 3SE moments later. I am very impressed by the level of service and customer support which Peavey offers.
