Even if you watch 10 video clips of LCD monitor disassembly at YOUTUBE, you will not find it very easy to do!! Do not use ANY sharp cutting instruments to "PART" the rear cover from the front bezel. One carless slip and it's a trip to local hospital "ER" to be sewed back together!!! Protect the GLASS lcd panel at ALL COSTS. YOU CRACK-IT, YOU BOUGHT IT, YOU OWN-IT, TOYOTA!!! 12fixlouie

Lcd benq t705 power button not working


When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Good luck!

Repairing BenQ 17′ LCD Monitor

I came across a common fault problem in BenQ 17′ LCD Monitor. The problem is have power but no display. Once you has opened the LCD cover, check the pico fuse for open circuit (very common), the push pull transistors C5707 for short circuit and the Buck royer circuit p-channel fet FQU11P06 also for short circuit too. For your information, if you can't get the FQU11p06 you can always use FU9024N as a replacement. Resolder all the high voltage transformer pins and replace the components above and I'm sure you will bring back the life of this BenQ 17′ LCD Monitor.
You may go to this fairchild semiconductor website to download the spec of the FQU11P06 P-channel FET.

Benq g2400w lcd monitor how to get sound working on the monitor only connected thru DVI


If this montor has built in speakers you would also need to connect the audio wire to the computer. It should be a wire with a green jack on both ends, You'll connect it to the audio in jack on the monitor and the green jack on the back of your computer. Hope this helps.

Benq FP731 LCD not start up, only green power lamp


Opening it will not likely solve your problem. Have you tried another monitor on the computer to see if the problem may be with the computer itself?

No sound


Dear marco1983,

there are no speakers on G2400W, just the plug hole for speakers that routes forward the sound signal from the HDMI signal.
