I brought my benq t701 to a repair shop to due blackout screen. But due to lack of parts, it was not repaired but all 6 transistors were removed from the PCB. Please show me where these transistors were...

go to and get the manual from there will be easier as the transistors are directional i believe they are 2sc5707s from memory but you will need to check the transformers and the 2 filter caps on either side of them as if they are faulty will blow transistors.

BeNQ FP71E Monitor won't display desktop

The problem seems to be with the monitor.When there is no Display,if you power-off and on again do you get a Benq Startup screen?If not the problem should be dry solder on the Invertor board.Try tapping screen lightly,if it comes on the problem is dry solder on Invertor board.

Benq lcd Displays only white

Most often the all white screen is the result of a missing voltage to the LCD panel. We usually find an open fuse on the panel circuit board. Unfortunately replacing the fuse does not usually fix the problem.

Hi Abadir, It really sounds like your back light has bit the dust. I can't always see stuff on the LCDwhen the back light is out. Check in with for parts, and repair of your monitor. I truly hope this helps. Good luck.

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.
