Why does the appliance not switch on

@juniorkasabe you are not telling us what you have already checked. Make sure you have a good power cable and that your electrical outlet is working. If that checked out ok, you will need to check the fuse F1 on the power board for continuity.

Let us know if you have never done this or if you need help with that. Whatever you do, disconnect your device from the main power and do not touch components on the power board until you discharge the capacitors.

Here is the Panasonic SA UX100 Simplified SM for the schematics etc.
