A few vertical parallel lines appeared on my Toshiba laptop screen. Now there are 15 lines about one inch apart! Brendan Caffrey
Connect your laptop to an external monitor. I expect the image will be fine, which will indicate a faulty LCD screen. If the lines look like example 2 on Laptop Repair 101 (above), then the screen will probably need to be replaced. Toshiba or an independent repairer should be able to estimate the cost. Searching eBay for completed transactions for your laptop will give you an idea what it's worth, and whether it's worth repairing.
