Hello zan_drx,

You can connect another lcd or monitor to your laptop to check if it's just the screen for your laptop.

Another possible scenario is it could be your video card, the RAM or the board itself that may need to be repaired or replaced.

Hope that helps.

Try to plug in an external monitor. The laptop should detect it is pluged into a monitor and if the LCD screen is the problem you will know. Also look very close to the LCD. If you can see it working very faintly, the backlight is burnt out. Good Luck.

I have acer 3050 is switch on but no display


Hi! Try to check if there is a hotkey to turn on/off lcd display. If none, try to power drain the machine by unplugging ac adapter and removing the battery.Press and hold the power button for 10 secs and then after that put the battery back and plug in ac adapter.Press power button and then check if you will see anything on the screen,if still the same then try to connect the laptop to a external monitor and then press FN+F5 to switch display to external monitor, if you see something on the ext monitor it means you are dealing with a faulty lcd on your laptop...Hope this helps...

Acer Aspire 5050 screen is blank


Hi, if it works with an external monitor it's more likely an LCD problem. When you push the power button, noting comes up on the main LCD screen? not even the Acer logo etc.?
Did you set your video card to use an external monitor and disabled the primary LCD? If so, you need to go to display settings, advanced and go to ATI Display and make sure that the notebook monitor is on.

Acer Aspire 3680 Laptop


hi,

1, make sure that your laptop got power. how to do it ? it is easy, the power led (close to headphone jack) is on. and power button led should be on. Just in case you can't power on, please check ac adapter and power port on your laptop.

2. i assume you have power. now power it on and press f2 to got to bios. press f2 many times, it should make a beeps when you press it many times. once you get a beeps, press fn+right arrow to adjust the brightness of lcd. did you see something ? what i am looking is dark display.

If your display is dark, open the power cover (power cover is cover where you see power button), you need to remove 2 screws on that cover, on lcd hinges. After you remove power cover, you can see cable close to power button, remove it and check the display again, is it bright or still dark, if it is still dark it could be inverter or lcd.

if your power is on and you press f2 many times, it doesn't make beeps sound. it is called no post. Reseat memory and if this still not working, your motherboard is bad. if you have 2 memory installed, try 1 by 1. sometime the memory slot is bad, sometime memory is bad.

i hope this troubleshoot will help you to find out whats wrong with your laptop.
good luck
