2 minutes after boot issue "buzzing" hum, indicating there is a microwave power after power output. Check the high voltage capacitors, high voltage diodes and microwave generators were normal; check leakage inductance of the transformer secondary resistance has less than 1n, a description of this leakage inductance of the transformer windings short circuit. After switching to the same type of transformer leakage inductance troubleshooting.5PSservice manual download site
