I have a Panasonic NN-A574SBBPQ, which suddenly failed with a small pop sound that triggered NCD device in fusebox and killed power to my house temporarily. Device is out of warranty, so opened it up and checked fuses ...found 2, both OK. Switched back on and tried a few things ... turntable* doesn't rotate and fans don't work, but grill comes on OK andon microwave setting will warm up a cup of water.
*I disconnected the turntable motor, wired up separately and it did seem to be working.
Any ideas?

Hi, does the lamp work ? this a problem with panasonic sometimes. the lamp blows and kills part of the control panel pcb. Remove this and check for damage. if you find it do not repair the track, the problem is with one of the diodes on the board, just repalce the board, not the lamp waste of time.
kindest regards
