First, I would check screen cable. try replacing it with a new one, you will be surprised to know how many display problems are are caused by a defected screen cable.
in case this is not the problem, it can get more complicated, but first, just in case, reinstall drivers. its a long shot, but if you get lucky it will save you alot of pain. in case it didn't help, It's probably a bad vertical output chip. if you have some familiarity with monitors and decent soldering skills you could probably fix it yourself, but I would advise looking into taking it to a shop, or at least find an experienced hobbiest if you're not yourself. It's a pretty straightforward fix for someone who knows what they're doing.

Apparently it is a display hardware problem.
Try another monitor with the same cable and video card. Then you should try another cable. Then another video card.
If vertical line doesn't show in either case, then you should replace the appropriate device\cable.
If it shows anyway, then bring your monitor to service center for diagnosis.
I would try connecting your laptop to another monitor or tv. If you have no issues then you know the problem is your monitor. If the problem is the monitor, a new one can be found for around $100. If the video issue follows the laptop, you may have to upgrade laptops when you are able. Also, try another video cable to see if that helps.
Yeah, I have this exact same problem, except my mom slammed my laptop shut in frustration around half an hour ago, so that's why it's like this. The right half of my screen is black with two colorful stripes (mostly white), but the left half is visible. I've researched a bit and found out that this is because the LCD in your monitor has burnt out, and since you don't have a monitor to attach, the only thing you can do is to go to where you bought the laptop and either get it fixed for free or return it for a brand new one (if your warranty still stands). If not, you might as well get a new laptop. I think my warranty has expired, so I'll get a new laptop, hopefully.
your monitor got a hardware problem:
1) the LVDS controler board out of work, only change or repair it could be fixed.
2) if you can see some show like smaller signal detect windows in the centre of screen a very short time (bright flashing one time), this is inverter board damaged or worn lamps, thay all need repair or replace
hope give you some idea. please take a rating let me know how much helped you thanks!
My Acer AL1711 packed up last week, I bought a new Acer and noticed they have a 3 year warranty. Give Acer a call on 0870 853 1000, and they`ll do a warranty repair with free pick up and return - great service! Not sure if you need proof of purchase or not, luckily I had mine.
