Hi. Just posting to say thanks for all the useful information I found on this forum.
My Benq FP767 monitor wouldn't power up. No signs of life when pressing the ON button.
I checked the mains input then had a look inside. The case is quite difficult to remove, As well as unscrewing the pedestal and all the obvious screws on the back, you have to lever open lots of plastic latches along each edge. I worked carefully starting from the corners and levering with a blunt knife, but I still managed to break a few of the latches. It's obviously not designed for ease of opening.
Inside you have to separate the electronics chassis from the LCD screen and disconnect all the connectors. Then you can turn over the metal chassis and remove the two PCBs inside. They are linked with a plug and socket and have to be removed together.
I found two bulging capacitors branded Elite, which I replaced.
C707 1000uF 35V
C710 1000uF 16V
Miraculously it worked straight away. Thanks to everyone on the forum for helpful information.
