10 + year old Plotter worked flawlessly until last week,, it would not plot but all panel lights lit properly. I turned off, to re-boot, but whhen it came on again all 8 lights blinked once then off/nothing. When I turned off the lights blinked again. I replaced the cartridge but NG. Then I took a chance and replaced the power supply in the ECM but it did not fix and the plotter still blinks on and off. Any advice is appreciated.

I found fine steel wool type dust surrounding one transistor attached to the heat sink on the main logic board. Once cleared with a puff of air all working again.
