vertical lines on my laptop screen

My laptop screen has developed vertical lines which seem to be increasing in number and intensity. Does it mean the screen is at the end of it's life? The laptop is about 6 yrs. old.

Could be the cable on the hinge side that is getting worn. Try moving the lid to and fro and see if that alters the display - either better or worse.

You could try updating the driver. I presume this has been happening over several days/weeks?

It could be overheating if the fan vent at the side is full of dust, with laptop turned off, use a vac to suck it out (never blow it in) you might need a cotton bud/small paint brush to disturb the fluff.

Another thing you could try: power down switch all off, take out battery and power cord and then hold in the on/off button for about 30 secs to remove residual static and empty volatile memory. Then put it all back together and boot up.

Vertical lines on LCD screen

Confirm the motherboard or video chipset as being the source of the problem by connecting the laptop to an external monitor or TV. If the external display is normal, no vertical lines, the motherboard and video chipset are functioning normally. If the external display has the same problem, you may have to replace the video card or motherboard.

Check the laptop's video cable, access the video cable that connects the screen to the motherboard. check it's pushed tightly into the connectors, gently flex the cable, or replace the cable and check the display.

If none of the above work, you may have to replace the screen itself.

In most cases, vertical lines on a laptop's screen are caused by the screen damage. If the lines change colour or get wider or narrower when you apply slight pressure from the back of the panel, the problem is probably caused by the laptop's LCD screen and will have to be replaced.

Is it worth to have a new screen for a 17 inch Toshiba 150 Satelite laptop?

Have you tried coupling to an external monitor?

a new screen is approx £80 if you change it your self.
