Re: my monitor sucks

Don't hit your monitor. JUST Buy a new flat screen, don't use CRT monitor. It has an effect to your eyes. You better save your eyes, don't save the money for anything else.

My i2352Fh monitor has developed a white vertical line which tracks back and forth across the middle half of the screen how do i get rid of it? the screen is 3 months oldn

Thanks Melony - had exactly the same problem - your post above helped me fix it...... Here is how to fix it .
  • On the base of the screen press the Menu button (far right),
  • Then press < or > to get to the Extra (looks like a screwdriver and spanner) and press Menu again to Enter.
  • Press < or > until you have selected the RESET and press menu again to Enter.

The line should be gone. Close the menus and all should be fine. I hope this helps someone. I searched the internet and this was the only post that gave me a clue. Thanks again.

How do I Fix LCD White Screen?

If you see "fractured lines" across the screen, it would appear that your LCD screen is broken. That's the only way these kinds of lines appear.
You need to replace the screen.

A big white vertical static band appears as soon a i turn on the power

Some of the transistors or the connection to the panel inside the monitor are damaged. There is no absolute fix for this problem.

You can try pushing on the bezel (NOT ON THE SCREEN) of the monitor at the edge of the screen directly at the lines and you may be able to push the connection back together well enough that the line goes away, but usually in desktop monitors the bezel is too rigid to allow you to put any pressure on the connections at the back of the LCD panel.

Mag innovision LT716s monitor

When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.

I know exactly what your talking about. I've seen in many times. It' happens too in CRT monitors as well as LCD. It could ALTHOUGH be as simple as a bad cable catching interference. Most likely though, it sounds like a bad LCD driver board or video board. If you have warranty, call it in. Otherwise see if it lessens with adjustments of contrast and brightness up and down. This directly affect the driver board power and can improve it enough to be tolerable again.

Lines across screen

The screen you have is almost certainly on the way out. This type of fault is in the Horizontal Flyback section of the Monitor. Usually components fault or age and change value, these lines are normally "Turned Off" so ya can't see them, that "Turn Off" circuitry is going faulty.. it will only get worse. I suggest a new, or 2nd hand monitor as they are so cheap these days fixing CRT monitors can be cost prohibitive.
