i have a dm2800 that i acquired a couple years ago from a friend whom passed away.

i had seen it running at his place when he last used it.
i brought it home and change the line from 220 which he had to the 240 on the transformer. (i tried it on the 220 first)
but it turns on the power supply and there is some clicking on the spindle and the spindle rotates a little then control say READY? after about 15 seconds the control panel loses power.

i am trying to sell this unit so i just want it to boot up properly. any ideas and help would be appreciated.
thank you.
