What actually happened?
My TV stop working at some point in time. The red dot does not light up and nothing happens.

Hope to have fuse problem which could be simply fixable.
Start with two holes on the bottom for getting cover off and then pull it step by step, latch by latch.
Ah, it is not a fuse issue

I have checked with multimeter and it turned out that fuse is not corrupted.
Checking voltage output

Remote control could not be used together with the “new” board as they did not know each other.
