Had a sinilar problem with an acer 19" moniotr, turned out to be the DC power supply board. If you know someone with an electronics background get them to check it out for you. I was able to repair mine in an hour, keeping in mind, I had all of the proper tools and parts on hand to do the job properly. If you dont know what you are doing I wouldnt recommend attempting a repair, due to high voltage supplies inside.

Benq fp581 screen goes blank after about half a second evertime i turn on my computer.


Even thought the monitor looks blank check to see if you can see a faint image (shining a flashlight at the monitor sometimes helps). If you can see an image it could mean that the inverter board has gone bad.

I have also heard of an overheated computer causing a similar problem.

Screen not displaying appropriate display at start up


Vetical line is the sign of failing LCD controller (t-con) board, which is part of the LCD panel assembly, it will get worst with more lines. You can try looking at the ribbon cable that is attached to the LCD panel and the Logic board to see it is not seated properly. You can look at what the connection looks like here:

You may also look for bad caps in the logic board and power supply board also.

Trouble with my BenQ monitor


As a general rule, this is a panel failing.
The panel is working for a few minutes until it heats up then begins to breakdown. Blowing air onto it wont help since the area in question is under another panel inside the monitor.
The video control board (inside the monitor that converts signals between your PC and the physical panel) could be failing.
Another source of the problem, though rare, is the capacitors that filter power for the panel's power supply (on the main powerboard) begin to break down and that is enough to cause the issue.

Because this is a BenQ, it may come back to life if you replace any capacitor that looks even remotely suspect & resolder all the main components on the powerboard.
Be warned, there are dangerous voltages stored by the main filter capacitor that can kill even if the monitor has been unplugged for several hours.

If it's a 71g and not 71g+ resolder transistors 2sc5707 on invertor board along with grey condensers and inverter transformer.This should solve the problem if it was display shutting off with power led remaining on.Otherwise check power section.

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.
