A bit late I know, but I have the same monitor with the same problem - see here . Problem with mine was one of the backlight assemblies had died. No mean feat to replace these. If you can do it yourself it'll probably cost around $50, otherwise it's for the scrapheap.

The benq Monitor FP222W automatically shutdown


Check if you dont have a timer shutdown on the menu.

Electronical Problem:
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!

Benq fp222w monitor switches on but black screen no backlight what parts need replacing to fix pls


If there's no backlighting but you can see the image anyway, then your monitor might have a defective inverter. The inverter is responsible for providing power to the backlight, so if it is defective, the light won't work and it might need to be replaced.
An LCD inverter looks something like this:

You can easily find inverters for sale online, but be careful: you have to find the exact same inverter for your monitor, or it may not work.

Logo appears then a blank screen


You need to open it up and inspect the PCB for bad solder connection or over heated components. BenQ made monitors for Dell, so look at some pictures of failed Dell monitors here to get some ideas what could have gone wrong with your monitors, post back what you see so we can guide you further: http://s807.photobucket.com/home/budm/allalbums

The monitor switches on and shows benq logo, then screen goes black.Tested on 2 computers and still not working. Have changed capacitors on board but still nothing.


After changing the caps, do you get steady 12~18vdc feeding the inverter circuits? Inverter fuse OK? It can be bad transformers, or lamps also. Pictures will be great help. See where I post my pictures: http://s807.photobucket.com/home/budm/allalbums

Wont power onPressing power switch, blue light comes on, the BenQ logo briefly flashes then screen stays black


Power leak causing overload on the O/L sensor.

Probably a faulty capacitor on the power board

Check to see if the video cable is connected at both ends securely.
Also, if possible, try another cable.

Power but no picture


Try to re-solder the inverter part of the board. You may recognize that part where the 4 connectors from the backlight tubes can be found.... usually the small transformators (sorry, my technical English is not good) have bad soldering eyes after longer use. This may work if backlight turns on for a few seconds, then the power led is still alight but screen goes dark.... the inverter then "thinks" one of the tubes might be defective and turns power off. Hope this helps a little...

Monitor Randomly Turns Black


I have exactly the same problem with my Benq FP71E+ ..

What i found is a temp fix is this :

When monitor dims and goes black i turn it off , hit the bottom left side (near the BENQ logo) turn it on again and it works ..

This works every time for me . But after a while it switches off again , could be 5 minutes could be 5 hours . Its random

Unexplained Blank screen.


Looks like your Power Supply has gone Kaput .. Usually it is the Electrolytic Capacitors on the Power Supply Board, try a new one, or replace ALL the Electros with same or better ones.
