Re: retrace line on monitor

To prevent serious damage and extend the life of your monitor you need to adjust the main brigthness control of it. it is of the LOPT/Flyback transformer inside of your monitor!

check also for cold SOLDER joints on the main pcb and also on the crt neck Board.

My moniter screen go's dark with a bright horizontal white line in center flickers

the driver board is bad in the monitor. Has it been in a place that is super hot like in a car? If the verticle driver chip disconnects from the matrix driver array, it will all squish into a single line in the middle of the screen like you are describing.. might try opening and blowing where the driver board connects to the LCD matrix (bunch of connectors on a plastic flat cable/bus connecting to the end of the LCD panel.. heating them could allow them to reconnect.. Its worth a try, right? It has worked for me about 60% time.

Monitor intermittent power problems. Horizontal green flickering lines

You have to check the ESR in tha caps in power supply with esr meter.
If you dont have one just replace all capacitors in the power section(there are severals of them)This is the simptom of low esr in the capacitors.
Return the monitor in factory settings.

There are moving lines from up to down (it is like flickering) continuously during the monitor work

boot to bios and check if the lines can be seen. if the lines are visible, you have a faulty LCD. if not, update the display driver or graphics driver.

FPD1530 (Black) 15 in. Flat Panel LCD Monitor: Screen shows, 'Invalid Mode', followed on next lin...

It means your PC video resolution setting is too high for this monitor to display.
You need to set the resolution to 1024 x 768 @60Hz. Bootup in safe mode (hit f8 during bootup) select VGA support, rest the resolution to 1024 x 768 @60Hz, reboot.

What causes vertical lines on screen, some lines are thick and some are thin and appear over the task bar, they are across the entire screen.

They are static lines. They can be caused by a variety of reasons, damage to your monitor, damage to your vid card (perhaps it was got a little too hot?), ive seen this issue also with overclocked, try resetting to defaults if so. Also try reinstalling/updating your current display drivers. If you have an integreated video card it could be that your motherboard got hot and perhaps damaged it. If you have a spare vid card or something else you can hook up to try, and it still has the static lines, then it is your monitor for sure.

Screen flickers for about 20-30 seconds sporadically

Try looking at the LCD screen at a sharp angle to see if ghost-like video can be seen during the 'off' time of the flicker.  If video is still present even though not that visible, then either the backlight or its power supply are failing. The color problem could also be caused by a backlight lamp that is not ionizing completely.

Mitsubishi diamondpro 930sb flickering

I have had the same problem with my 991sb and most recently my 930sb. The first was replaced at NEC's expense however on this second one i'm out of luck. I think its a problem with its power inverter. It may be repairable by a tv repair place. I'll be looking into it and let you guys know.
