Is it the LCD
I have a Compaq Presario V5309wm with trouble the display.Most of the time the view is good for the fist 1.5 inches and then It goes dark. The further you down the screen it changes to white,, if I am looking at the BIOS (External Monitor is perfect.) If I am looking at windows the instead of the lower part being it is is vertical lines of color, (External Monitor remains Perfect). The lines of color appear to change as the colors change on the monitor, yet it does not appear to have any intelligence driving the horizontal scan.
Is it the LCD, INVERTER, MOTHERBOARD, or something else? How Can I tell?
Is this a good question?
