My Acer screen has frozen and now looks a bit like the video channel on a TV, ie two broad white vertical series of lines. I cannot switch off conventionally, or by the on/off switch, or by closing the lid. Has anyone else had this problem?

Re: Can't switch off
This normally is caused by faulty Memory specially if your laptop depends or is getting shared Memory from the RAM.
recommended solution: Try to remove theMemory/ies and clean the contact using a soft pencil eraser. Make sure that you lean both sides nd avoid touching them after cleaning.If yu have done this and still have same problem try to remove and alternately install the memory one at a time. If still same problem I suggest you bring your unit to the nearest shop to do Advance Hardware checking.

The video card (built-in on the motherboard) maybe faulty or the LCD screen is faulty. Connect an external monitor to the video port of your laptop, power up the monitor first then boot up your laptop. If the video card id OK then the laptop will automatically divert the video to the external monitor. Then the problem is a faulty LCD screen. If the external monitor also displays black vertical lines then you have a faulty video card and since it is part of the motherboard it is impossible to fix.
What is happening to your laptop is the power line connecting a row of pixels is failing so only partial colors are showing up causing the vertical white line. Usually screen replacement is the only answer to fix it.
You mention in your post to branded laptops. You can try to check if the problem is from the LCD or from the Video card. Connect your laptop to an external monitor and check if the white vertical line appears, if yes replace motherboard if video card is integrated, if expansion then replace video card alone. If no lines from the external monitor then laptop LCD has the problem.
It very well could be a easy fix, Usually the Ribbon which connects from the LCD screen to the Notebooks motherboard gets bent/torn/damaged by extensive CD movement.. A close look at the Ribbon, if reveals tears or any damages a new (10-15$) Ribbon Cable may very well be in order if not a new notebook itself.. :-)
you’ll need two outputs on your laptop that are typically found on most: the first is a small round yellow socket usually found on the back of your laptop, which is the S-video socket. The other socket you need is either a line out (unlikely) or headphones socket (more likely). You also need a TV with the correct inputs, which will ultimately decide which cables you need
First, you need two separate cables for video and audio: S-video to S-video...and Stereo 3.5mm plug to 2x RCA plugs..Both cables are two metres long and longer cables are also available..Your TV will require either equivalent S-video and RCA audio inputs or a SCART socket - if it only has the latter, you’ll also need a SCART adapter
Once done, plug them all in and switch your TV on, switching to the A/V channel. If nothing appears, open the Display Properties Control Panel, switch to the Settings tab and click Advanced. Look for a Display tab or something similar where you’re able to switch on the S-video port to enable the laptop’s display to route through the TV. Finally, when watching DVD movies (you’ll need a DVD player to do so), look for the option to run them full screen, so you get the best possible picture from your TV.
