Resolder the power transistors on inverter board and also check them.If display is not there at all some of this 4 transistors C5707 should be defective.Check associated fuse and Fet which drives the transistor.

Also check with Benq ,Normally offers three year warranty.

SOURCE: Monitor displays desktop for a short while

this kind of trouble is very common to all LCD monitors. your inverter is shutting down. please check all capacitors at the power supply some are badged or blown on top due to hot pressure inside.

Benq T701 LCD monitor


I had a similar problem: the backlight on my Benq T701 only functioned for a couple of seconds every time a turned the monitor on and then the backlight switched off (sometimes in two stages). An electronics guru at work said with those symptoms the transistors rarely were the problem and I just needed to resolder the connections of the high voltage coils onto the PCB. On visual inspection those solder connections seemed ok, but when I tried to reflow the existing solder at one connection I spotted the problem: just a thin surface layer of solder was present and I had to add solder to fix the problem. The 4 coils each have 6 leads on one side and 2 on the other. I only soldered the connections on the side with 2 leads. In just 30 minutes and without buying parts the monitor is now up and running again.

No display


if your monitor is not connected to a pc, then it cannot find a vga signal input and therefore go into power saving mode, which is indicated by the orange light, but as soon as you connect to the pc and power on the light will go green and the monitor will power up.
