Hi, this monitor just stopped working. The green light and display come on for about 2 seconds then switch off. Sometimes it's less. Have tried different power cord and different computer but same problem. Anyone got any ideas?

SOURCE: Benq FP71G LCD Monitor - Can't keep POWER ON / Button Problem?

I had the same problem and found that Q808, Q809 and Q805 had failed and which if left long enough can also cause PF801 to fail. I also replaced all of the electrolytic capacitors during the rebuild as it was only a few dollars to do so.

Although in my case Q815, Q816 and Q812 were fine I suspect that they may also fail in time.

Here are the parts which should be available at most electronic stores or online.

Q808 & Q809 - 2SC5707
Q805 - IRFU9024N
PF801 - 3 AMP PICO FUSE

Hi,

The picture board on your monitor is bad, since the lines are causing visual display, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself. in other not to complicate issues.

I have a BenQ FP71G+ monitor and the auto adjust message pops up frequently and the screen adjusts itself.


radioactivet, A qualified technician will need to investigate the units "switch-mode-power-supply" for typical "faults" and locate the faulty (bad) component(s) that ma be causing monitor to act this way. "Noise" on the +5 volt DC rail going to the vga/lcd interface (processor) may be why display is acting "strange" with uncalled for pop-up's appearing!! That's the very first place I would investigate when dealing with ANY COLD-CATHODE-FLUORESCENT-LAMP, BACK-LIT LCD DISPLAY. 12fixlouie

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.

When i turn on my monitor it shows my desktop then shuts off after 10 seconds...never stays on


elainenemeth, Hi, Tell me more! How old is this LCD monitor? Is it out of warranty? Did the "SHUT-DOWN-IMMEDIATE" problem occur without warning? Did the BenQ display a "perfect" image the day before? Did you actually count----1001, 1002----1010 and then it shut down, after pushing the monitor on button. Did you do the "flashlight" test? With monitor connected to a "known-good", fully booted pc with Win Desktop displayed, TURN ON the monitor! Did it display the desktop for 1-2-10 seconds ? What did you see or not see when you pointed the flashlight at different angles about 1-2" inches from the now dark (black) screen? Get back to me with your results. I will offer the best advice possible to you as a consumer/user of LCD/FPD monitor. I'm louie12fix on fixya or lmistyrel @ aol.com Bye for now.

Hello
I have had this problem twice once at my school and once with my BenQ FP71G Monitor. At my school the monitor ( HP ) just stopped working and smelt like burnt popcorn.(though is think this is due to some kids chucking a soccer(football) ball at it! With my BenQ it has the same problem though i nownthink it is because of the monitor has been on for excessive hours ( 3-4 ) and just shut down because of overheating. I will see in a couple of hours if it works !
