Benq E2200HDA Monitor weird sound

[arthurmod]

Hey,

I have a Benq Monitor which has a strange weird sound coming from the PCB with the image flickering and then goes blank, after I re`power the monitor the image appears but with the noise and then goes blank after couple of seconds. LED is green, it doesn`t go on standby. Checked the cables, even the video card, all good.

Thanks

Attached is the service manual, take it apart and post pictures of the power board.The big capacitor could still have a high voltage in it so be carefull what you touch.
