Blue vertical line on LCD; seems a common problem - here's what works for me?

Question

It's a ViewSonic VX2235wm 22-inch. The line appeared at random, then vanished at random. Did this thrice. Then it was there to stay. Then, I read somewhere about "tapping the bezel"; I did that near where the blue line is, and it vanished. Now:

1. Is it an LCD, graphics card (GeForce4 MX 440), or connector (VGA) problem?
2. Will service repair it - because it goes on and off? Suppose it's off when they inspect it?
3. Why did tapping on the bezel work?
4. I ran those screen generators (you probably know about these if you've read thus far). Then,
4.a I tapped the bezel *after* I'd run the screen generators. Did the screen generators make a difference?
4.b The software helped tremendously in improving the picture, though the monitor is only 2 weeks old. So what's up? Is my monitor bad? Do people run these videos often to keep their LCDs in good shape?

Please answer as many of the above as you can - I'll offer you a pizza with all the toppings *if* you can come over to my place!

Answer 1

1) Neither.

2) if they catch it happening, or trust you they will repair it.

3) What you have is a loose connection on the column drivers that send a signal to each column of pixels on the panel. Tapping on the bezel reconnected it. For the moment.

4a) What is a screen generator? I doubt it made any difference. This is a mechanical problem.

4b) I suspect that the program allowed the monitor to do a better job of setting itself up. It did not renovate or improve the monitor, it just gave it a better signal to set up on.


Where do you live? (LOL)
