    Do you mean it wont boot up or turn on?

    Do you get anything on the screen when you first power ON?

    do you have a recovery CD? can you boot from it?

  • Dave Jul 17, 2008

    Are you able to connect an external monitor? I want to see if the black screen is due to the back light on the laptob being faulty (turns on then off for some reason)

    I think it is standard on Acers to use the Fn + F5 hot key to toggle the display setting between the computer's LCD panel and the external display device

  • Dave Jul 17, 2008

    OPPS my bad... got crossed between issues....

    Sounds like it is not detecting the video input, have you tried it on another PC? try this and also try replacing the VGA or DVI cable between the PC and monitor.

  • Dave Jul 17, 2008

    Doing some research, there was a similar issue with another model...

    the short term fix was to Unplug the monitor reset the video controller.

    Try unplugging the VGA while the PC and monitor are on. power off the monitor and reconnect the VGA and power ON

  • Dave Jul 17, 2008

    Also try unplugging the AC connector from the rear of the LCD and then reconnecting and power ON

  • Dave Jul 17, 2008

    also pretty sure this will have a 3 year warranty if these ideas dont help.

  • Dave Jul 17, 2008

    just a thought, can you connect another monitor to the PC and reduce the res to say 1024 x 768 and see if it will display on the "faulty" LCD at the lower res?

Can i upgrade my old monitor to a new acer 19" Acer Monitor

Hi Ricky,
In most situations you won't need any special connections, as most LCD screens have the same VGA interface sockets and cables as your older screen.
Let me know if I can be of any further assistance.
Best wishes,

When i boot up my pc , the monitor light comes on but flashes and the screen doesnt come on for anything from 1 hour to 4 hours

You need to establish if this is a monitor problem or a problem with the graphics card in the PC. Can you try another monitor or have you tried turning the monitor off (for a long time) separately, leaving the PC Base running, then turn monitor back on again? If it takes time to come back on while the PC is running, it is likely to be the monitor at fault.

Hi, i have this acer 1912 19" lcd monitor, it won't turn on (actually it will turn on if i wait for a few hours). if i unplug the vga cable and press the power button, it will display "acer...

That's kind of interesting that it comes on after a few hours; what changes during that time, I wonder?  I also wonder what changed since it worked last, for example a power-manager utility on the computer side which isn't quite compatible with the videocard; it seems unlikely though.  So; please describe what happens over those hours: is there a profoundly blank display, or generally dark display with no backlight?  Does it just pop back to perfect operation, or is the backlight out (as if the monitor's sleeping, though the power LED indicates awake) and eventually coming on so you can see what's there?
  I suspect that the backlight is starting to go and the startup circuit (which takes the most stress) is cutting that section out of operation for a while; perhaps the monitor's microcontrollers or a circuit protection device resets.  if you want to open it up you can clear out the dust and look how the backlight and its power units are fitted, and maybe take some pictures for reference, thermocouple readings (temperatures!) on the backlight power sections and backlight itself, solder wires on the backlight so you can get voltage and current readings, and get the backlight make and model.  You can probably convince the same backlight to go for a while longer by cleaning up the supply circuit and replacing a component (FET or circuit protection VOM) that's too hot because of its own derating.
