I have an iMac 17" that has just started to have a vertical line - blue in color. How can this be fixed? It's 3 years old and nowhere near a technical support person.

Hi there.

I suggest you see my tip on fixing the vertical line problem here: http://www.fixya.com/support/r9352105-fix_colored_vertical_lines_lcd_display

This is typically a bad or loose cable to the monitor inside the computer. While you can open the iMac, Apple doesn't make it easy. It requires special tools, and there is a lot of tape involved. You can go to an Apple store to get it fixed, or to most computer repair places. It will likely cost you a little more than doing it yourself, but if something gets messed up in the process, they will be on the hook for fixing it, while if you did it yourself, now you have two things to repair.

Although its possible for graphics processor failures to cause vertical lines, they more often create horizontal ones. The first culprit to check for a vertical line problem is the LVDS cable, which it turns out is not that expensive a part (not counting all the work there is in getting to it). To verify this, I would gently flex the cable while the iMac is open and operating, and see if the lines get better or worse. It may also be that the cable itself is fine and just a few of the connector pins at either end are intermittent, in which case it just needs reseating.

How long is a piece of string? is the kind of question you've asked. I've a sneaking suspicion you'll get sick and tired of it before it finally goes.

looks like the lcd panel is damaged contact the toshiba service on your area

It is called "Thin vertical lines" and change colors depending on the background color.
It is fixable but there are several components that can show this sympton.

You will need a tech to fix it in order to save money (because you do not want to buy a board you dont know if will fix it).
Possible Solutions:
Replace Timer Control Board, if it is not fixed
Replace Sustain Board.

One of those boards needs to be replaced and I wrote the most likely first.

The line is an indication that there is a failure in the display, most times the failure will be limited to the line you see but occasionally the problem will spread, causing more lines. the only way to fix it is to have the display replaced.

could be the vga car4d problem, try to hook up with another pc if the problem remains then unfortunately the monitor is dying.
