Runs fine untill i plug lcd in ,then shuts down

Maybe the lcd screen is going bad. Try an external monitor. if the external monitor works fine then your lcd screen on the laptop is going bad. If the external monitor behaves the same way, then the Video Card on the computer is going bad.

Plug in an external monitor and see if thedisplay shows up on it. It can be any kind of monitor even the old big fat crtmonitors as long as it has a vga cable to connect to your computer's vgaport. If so that proves your video card is ok. The video will showon most systems when you reboot without you having to do anything. Some systemswill require you to hit the FN (Function key) + F1 thru F12. Hold downthe FN key then hit the correct key for displaying on the monitor (F1 thruF12). The correct key will normally have CRT/LCD on it or it will havethe icon of a display.

I think you are hitting the wrong Function Key combinations. Why are you using an external monitor anyway? What is wrong with the laptop's LCD Screen?

Each time you press the FN key plus the correct Function Key it toggles the Display between three stages (Show on Laptop only, Show on External Monitor Only, Show on both the laptop and the external monitor).

your memory may be bad,try and fix another memory{ram)

Had the same problem took it apart and found 5 capacitors on the power/inverter board swelled i replaced those with new ones then it worked perfect.. there were 2 1000uf 25v and 3 330uf 25v swelled.

Hi there.
The keyboard toggle you are using is the correct one.
Sometimes you have to hit Fn + F5 a couple of times to stay on there is no real set time. Make sure Fn + F6 is on so the laptop screen stays on.

Good luck and thanks for using FixYa!!

if you dont have any view on external monitor too  there so 2 reasons for.  1 is mainboard (graphic chip) 2 is LCD data cable that comes from Mainboard and goes to LCD.  need to go to Service 

I think there is some severe problem in the VGA of the laptop, that is not supporting your LCD. There may be some thing relating to a very sensitive golden color strip in the laptop that is used to VGA signals. If you have opened the laptop for repairing then it can be a issue. Better to try another VGA first and then tell me what happened.

Have you tried hooking up an external moniter? If so do you have video on that moniter? If you do have video on the external moniter then you most likely have a bad inverter or a bad lcd panel.I would replace the inverter first because it's not very expensive.If that doesn't work then you can replace the lcd panelAnd if that doesn't work you have problems at the system board level.

the LCD screen is damaged.

hope this helps

-toggle the laptop display using the FN keys and F5 I believe. -lower laptop resolution to 800 x 600 -look in laptop display properties for lcd or external display settings, see if it (external crt) has to be enabled on the laptop first.
