Question about Mitsubishi DP930-BK (Black) 19 in.CRT Conventional Monitor

1 Answer

Screen goes black with white horizontal line.

The screen on my monitor goes black with a whitish horizontal line in the middle of the screen. I saw noone answered a similiar post where the line was 15% up from the bottom of the screen. Would that solution apply to me as my line is 50% up from the bottom of the screen. If so, can this be done at home.

Re: Screen goes black with white horizontal line.

WHEN does this problem occur? Does it ONLY happen after the computer loads Windows (or another OS), or does it happen as soon as you turn the monitor on? We really need more information before we can provide specific advice or suggestions... IF this happens as soon as you turn the monitor on, switch it with a different monitor. If the problem goes away, the original monitor is defective, and probably not worth the cost of repairing it. If the problem ONLY happens after you load Windows, boot the system into Safe Mode (press the F8 key during bootup until you see the menu which allows you to select Safe Mode), then reboot and see if the problem has been resolved; simply booting into Safe Mode, then rebooting the system into Windows MIGHT solve this WITHOUT requiring you to change any system settings... IF the problem remains in Windows AFTER you've booted into Safe Mode AND rebooted back to Windows, the videocard driver might be corrupted. In that case, you'll have to reinstall the vidcard driver to correct this problem... If all else fails, it IS possible that the videocard itself is defective; if installing an updated driver doesn't work, try swapping the videocard with a different one. BE SURE to uninstall the OLD videodriver, and install the proper one for the new videocard; if you don't install the correct driver, you could create MORE problems than you have right now...

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.

When watching movies on my computer, I am getting a weird line through the middle of the screen at times, also, when things are moving on screen faster, more lines seem to show. I guess they don't really...

i think your vertical IC ( if vertical lines are shown) / horizontal IC ( if horizontal lines are shown) of your monitor has damaged. you may contact a mechanic and change the corresponding IC

No image but only a bright white horizontal line on the middle

Be it a LCD or CRT monitor, in either case, the screen is gone. Either service or replace.

Monitor goes black with a white horizontal line across the middle of the screen

Check to see that the monitor cable is correctly installed. Also, make sure you have the most up-to-date drivers installed for your graphics adaptor card(both ATI and Nvidia carry catch-all driver programs to keep you up to date.) Tighten the cable screws of course, to make sure the monitor cable isnt just wiggling in its seating.

Yes. There is no vertical deflection. The circuit that controls vertical deflection is bad. This is an easy fix for a TV tech. Take it to the TV repair shop.

Philips monitor problem

Check that the pc to monitor vga lead is not loose at both ends, check your graphics drivers are upto date, although it could well be a monitor fault and replacment required, as don't think they are worth reparing these days
