I have Humax 9200T with LG flat screen TV. nothing else connected to either. It developed a hum . The hum seemed to be controlled by the TV volume control. i.e. if I set Hummy volume to max and TV volume low the hum was OK but incfesed with increase in TV volume setting.
evenually the Hummy died. i.e. no output no lights etc. .

Any suggestions for cause of the "hum" and or repairing or replacing the PSU.

Failure of the main smoothing capacitors.

Unfortunately running it to destruction in this condition has probably caused more damage.
