Thank you again, I WILL fix it, this is how I learn.Nobody mentioned not helping you. This is probably the best forum on the web!!
Have you verified that the mains cable is not damaged. Continuity.
Have you checked the internal fuse. Continuity.
If all is ok so far, plug in the unit and check for supply voltage coming in. Is that correct?
Check the cables going to the power swith. And the switch itself.
You have to start somewhere and continue along the line. Have a read about transformers, thermistors, switching regulators
and how to test them.
Also diodes and bridge rectifier checking. These can be checked with continuity.
Your unit is quite complex, but I think the fault will be on power supply.
