You need check
1) make sure the line is stable or changeable there when you folding the LCD lid or touch lid somewhere. there is some temp disconnection if the line changes sometimes
2) check and make sure the LCD cable and the plug/socket at motherboard and back LCD panel, they are no dirty and disconnection
3) make sure the LCD panel hardware damage (replace one) if the lind is stable there, mostly should change the LCD panel.

I have a horizontal white line has been appearing recently on the bottom of my lap top's screen, i have not installed any new software and it hasn't fell down like ever ... what's the solution...


Hi,

Just boot to BIOS (either by pressing Del, F2, F10 (depends on the laptop brand).. upon turning on the unit). If the white lines appear, your problem is with the LCD screen.

If no white line in BIOS, install an updated driver of your video card. However, if installing the driver doesn't help, your video card is faulty.

Hope this helps,

Does the laptop have integrated or dedicated graphics?
This could be a problem with the graphics drivers. Go to the Toshiba website, and get the latest drivers for you PC, this should solve the problem. If this doesn't solve it, than it looks like the screen / graphics controller / GPU is failing.

White lines on screen


im sorry my friend I do not understand what a funny marrior is? LOL If your complaining about white lines at only the top of the picture, then I would say that your problem is with the vertical sweep circuit. Most likly a capacitor in the vertical preamp really small ones next to the jungle IC or the capacitors that are used as waveshapers in the vertical drive and output. If the entire screen is white lines then the screen drive is too high so back it down till the lines just disapear. if that wont turn down, theres a filter cap on the sweeop supply or the CRT socket board is bad. Good Luck
