under the outer cover,its either a 10-15-or 20 amp ceramic safety fuse avail at most hardware stores, the amp rating is on the side of the fuse, if the new one blows then either the H.V. diode/capacitor or the magnetron can be suspects

"On each panel the board surrounding the same diode is burned"?
Maybe that's a three-tap power relay, not a diode?

Sorry to read about your problem, I hope this helps you out.
you will have to contact a service company, microwaves are complex. if you order a part and try to fix, their are no returns. plus lg parts take a long time to get, and then way the cost of repair.
Microwaves must be serviced by technicians due to the inherent dangers involved in repairing these appliances. Internal capacitors can retain a lethal electrical charge even though the unit is completely unplugged. A microwave radiation leakage test must be performed on the unit following any internal component repair.

A microwave can be dead for many reasons.
If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to
open. When it cools, it closes the circuit and allows power through again.
If it's random, it may be a bad connection, usually on the control board or fuse holder.
If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.
If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.
If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.
