I have a Sharp MX-M850 that do not switch on. Actually this machine has not been working for a while, i mean years. So i want to bring back to life.This machine does not power on at all, not eve a light on the display. So I decided it is better to come up with a complete set of tested and properly working circuit boards. To my surprise same problem remains, machine do not switch on at all. Any ideas on how to resolve this problem.
