How do i open up

Can't say I am familiar with that exact model, but usually there are screws hidden under name plaques and other glued-on paper. Then usually the edges have tabs that "hook" under the opposite edge so even after you get all the screws out you have to insert something to unhook the tabs. But before you do all that, I have not seen many fuses inside a monitor.

My aoc lcd monitor appear full white screen

Most probably failure in the LCD controller IC in the lcd controller board. that no signal was sent out to the lcd driver ic thus you could only see white display on the screen. A replacement of LCD panel might be the solution. regards

BenQ FP731 Screen briefly displays then turns off

hi. i had the same problem and fixed it. the problem are the 4 transistors (C5707) one of more are shorted (Q739,Q740 and Q759, Q760). Also the fuse PF751 (3a) has to be replaced in most cases. In my case i replaced the fuse and 1 transistor (C5707)

No picture on screen but

Here is a couple of suggestions for this monitor. 1st check your connection to the computer.
make sure the VGA/HDMI/DVI is properly connected. 2nd check to see if the monitor is setup
to use the right source. Some monitors do this automatically others may need to be manually set.
either look for a button to do this or bring up the monitors menu by hitting the menu button. If the monitors menu button does'nt bring up a menu when the computer is off then the monitor is probably bad.

If the monitor works until the OS boots then goes black. The video card in your computer is set up
improperly with the monitor . In Windows hit F8 as the OS boots this will cause the computer to boot in safe mode. Once in safe mode right click on the desktop then go under properties then settings and change the display option to the correct monitor. You can also go to the device manager in my computer under system information, hardware, device manager and change the monitor here also.

Screen shuts off after 3 seconds

Failing power board capacitors, capacitors store the charge necessary to fire up the monitor, if they leak or blow, the power cannot make a circuit and the screen will shut off

Possible short in the main board, possible in the display drive power. The set triggers ON but the error makes it trip off due to the fault. So disconnect the main power to the driver IC -and check, make sure that all the leads on the board are having good contact- NO DRY SOLDER.
