My 3-yr old HP laptop is showing random horizontal red lines on screen (it has 17-inch screen)
Is this easily (and cheaply) fixable or I have to buy a new one?
Quite disappointed - didn't expect this on a not so old laptop. My previous Sony laptop still works fine after 9 years.

Random? lines in different places? same place but sometimes there or not? random relines all the time?
It could be:
1/ the panel
2 /the ribbon connector
3 /the Video GPU
4/ the software drivers.
1/ Twist the lid slight and GENTLY while its working to see if it changes
2/ Half close the lid and open it again a few times while its working to see if it changges
3/ If its this you are screwed, BUT the machine could be overheating*, is the fan running a lot? feel hot? blow out the inlet and outlet air vents
*recent HPs are a bit prone to this
4/ Unlikely to be this, as it smells like a hardware issue, but just to eliminate them, update your video drivers. Or go back a few levels.

Most of the times the lines are top & bottom 10% of the screen and 20% on the right hand edge of the screen.
They appear for few seconds and then disappear.
I run an app showing CPU & hard disk temperature and they are not showing high temperature.

Not a Pavillion DV9000 by any chance is it...?
Have just had a black screen episode with ours. Thought it was the cable so replaced that but still blank. Then it started working again! New screen now on order....
There is a problem with these overheating the graphics chip and melting it off the mobo, but that gives a black screen at start and failed POST with bleeping to suit. I've got a spare video cable now that's probably OK if it's any use to you....!

When my Dell6000 did the black screen thing my (correct) first guess was backlight power supply, new part less than a tenner from eBay, a cheap fix if you're handy with screwdrivers and plastic clips.

I think this is the issue with my laptop. When lines appear (very random) I noticed half closing the lid and opening again often cures it.

Then its probably the ribbon cable or the connectors are loose. If you dont fancy getting the part or fixing it yourself, your local repairer should fix it for 50 quid or less.

If you go into Safe Mode (tap F8 key at boot up - select Safe Mode) do the red lines still show?

My Acer Laptop Screen died 2.5 weeks ago - all well and working now
It was a loose connection but this was only proven after the ribbon cable and other possibilities were tried and failed to fix the intermittent screen fault.
£50 and grief using a 2002 desktop with Server 2000 with very little memory.

£50 is about right for that sort of job.

We had this earlier in the year from our 3yr old laptop which suffered from rough handling by teens. It would show vertical lines that would move if you twisted the screen. Then one of the hinges started to break so I sold it on EBay with faults declared and bought a new one with far better performance and a massive increase in battery life.

I've finally fixed ours...initial screen sent was wrong size to had to go back, installed and OK, but then the back light was on and off. Eventually traced it to a fault 40 - the installer of the new screen had not pushed in the LV cable to the inverter properly....! New cable and screen seems to have cured the crashing problem we were having too, and a prune of old software and startup rubbish has improved the speed. Going to download the programs Rattle mentioned in another thread and give it a clean up this week to see if I can avoid a Windoze re-install.

I use the free version of Austlogics BoostSpeed from MajorGeeks:
store.majorgeeks.com/p13357-auslogics_boostspeed_5_se
Had it on my system for at least a year now and also use it on friends' systems - the amount of unnecessary junk it finds can surprise.
