Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially and based on "...changed the fuse!...", then are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?

If yes, then proposed preliminary checks (if have not been done and dependent on the version):

  • • unplugged, check continuity of pins 1 and 2 of connector CN1;
  • • check thermistor TH1;
  • • check capacitors C14 and C15;
  • • check bridge diodes D1, D2, D3 & D4;
  • • plugged in, check the AC voltage input to the ~ of bridge diode D1...D4;
  • • check the DC voltage output of the bridge diode D3 & D4;

Please post back results / observations of the above once done.

A friendly reminder: voltage measurements by its very nature is carried out with the unit plugged in and therefore LIVE! Please exercise due care and caution.

I neither have access to such a device, or any familiarity with one. Nor do I understand any of your considered response, but I do thank you for your time!

I understand.

If not a DIY, then repairs or replace.

I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
