Testing a Laptop LCD

[spike47]

Hi there

I have a Latitude D600 and the screen 14.1" has gone blackish , you can see the backlight in the background , it will come on sometimes , I have checked the lcd lead with a ohm meter and it seems to be ok , not sure what the the problem is , when I connect it to a external monitor it works ok , the backlight is coming .I suspect it is the LCD , but I would like to check for sure before I part with my hard earned cash .

Question , I have a spare 17.1" LCD from a Toshiba P200 , with the same Connector on the LCD ( 30pin ) could I use that with the Dell Invertor to see if there is a signal / feed from the MoBo connector .

thank you

The fact that your laptop can fire up another external monitor really doesn't isolate the problem to the panel on your laptop. It could be the connection to the LCD from the mobo or the panel itself.

You have checked the invertor board on the panel as well as assured the connection is complete on the back of the lcd panel?
