Re: Fix for Benq FP737s 17" (Q7T3)



I have replaced the transistors in pairs, the mosfet and fuse. If I turn on the Montor now I get a white screen. I turn on the PC, I have a very normal Windows screen. I turn off the monitor again, the screen is white for a sec.
Do they have a solution for white screen?

Re: Benq Q7T4 (FP71G)

The MOSFETs have I changed the fuse and also the transistors and .22 caps. The other capacitors I have left alone, since I have no direct way to test it. The converter I have soldered, brazed solder removed and resoldered. With the above measures, I have just assembled the TFT again, and lo and behold, it touches on something. Unfortunately, the joy was short-while. The monitor has displayed a picture of exactly 2 seconds and then switched back to orange light. This can be repeated as often as desired. Switched on and off again, then another 2 seconds and picture...

Re: Benq Power Supply DS-1107A

i have an FP767-12 / Q7C3. 4x 2SC5707, 2x MosFets and fuse were replaced. Thereafter, the monitor can only be manually switched on/off with the power button, so no more about the connection cable or the PC. What could still be broken?

Re: Fix for Benq FP737s 17" (Q7T3)

I have here a Benq 767 and have replaced 2x C5707, 1x FU9024n and 1x fuse MS3A. The backlight is working again, but it is not switched off, so even in the standby mode on. What can still be broken? Someone an idea?
