Try an external screen to check where the issue is. If the external display works, the internal display is either turned off (F3?) or faulty.

Sorry, no. There is an on-board GPU that drives the display on the mother board and without it, there is no display.

It seems that your notebook does not have sata connection to Hard drive. Your harddrive is IDE connection. Sorry but you can't use SATA on this laptop.

VERTICAL WHITE BAR ACROSS THE LCD SCREEN


Almost certainly the LCD panel has failed, and would be replaced by Dell if it is still under warranty. You can try to replace the VGA or DVI cable that connects the LCD to the PC. If the problem persists it is the LCD.

Very faint vertical bar moving across plasma screen.


OK... Left to Right is weird. I'd say one of two things.
Refresh Rate might be to low or to high, but i doubt this to be the cause. I'll put my money on external interferences. Something like another PC screen? TV? anything magnetic and I've even in some cases noticed PC side panels too close to a screen can cause this.

First attach laptop to an external monitor and using the FN/ F keys toggle back and forth to the external display. If the external works OK then the video display adapter is fine and the problem is the TAB welds on the LCD. Time for a new LCD.

No picture with Vertical bars across screen


It sounds like one of the flexes on the LCD cube has either become unplugged/ loose, (there is a gate that locks the flex in connector on the DMD board), or flex damaged. Has the TV recently been moved or strongly jarred?
