Oh, well that is a particularly rare problem. However on this occasion these may be the problems.

1) The video card may be going bad
2) The monitor's connecting port or wire is damaged
3) The monitor's bulb is dying
4) Strong magnetic field surrounding the monitor causing massive interference

Observe these problems carefully and figure out which one it might be and get back with me as soon as you can so I can give you a reasonable solution.

Thank you!

HI my viewsonic monitor is hving problem when i switch on my system it shows me a horizontal line on the screen, except that line i cant see any thing and eveything else is black on the screen..


The entire image is squeezed in that thin line because the vertical deflection unit has failed - the monitor will have to be opened, the vertical circuit identified and replaced - all this must be done by a repairman so take it as fast as you can to one. If you keep it functioning this way for long the screen will be burned.

My Dell 1521 was working perfectly until this morning. When I tried starting it later today, the LCD screen no longer worked. The top third of the screen is fine. The bottom two thirds are covered by lines...


Your LCD has either gone bad or the ribbon needs to be reseated.

Carefully pry the plastic cover that runs parallel with your LCD. You will see the ribbon to the monitor. Press the connector down and make sure it didn't come loose.

Restart Windows.

If that doesn't work, then you will need to replace the LCD screen. You will not have to replace your lid...just the LCD. That should save you some money.

Hope this helps.

Detach the monitor from the cpu and turn it on. If the same vertical line appears then take it to the repair centre.

Carefully give your monitor a quick slap on the top or side, NOT like you would hit an assailent, but more like you would hit your brother if you were kidding around with him. If you get a positive outcome from the slap, you have located your problem.
I'm assuming a CRT type of monitor. Probably the monitor has either a bad connection inside it or is simply dying from old age. Vertical Deflection grids supply voltage so that screen stays full top to bottom. If the output of the VDG is abnormal or missing, you will experience the horizontal line across the screen.. Unlikely to be the video card on the computer, generally speaking intermintency is not a common problem with video adapters, not to say that it couldn't happen,

Emachine W3400/ front panel connections


they have to be plugged in horizontally although it is possible to plug them in vertically because the pins are evenly spaced either way. they are color coded just not like you would expect for example one plug has a green wire and a white wire the green side goes to the green pin and the white side goes to a green pin with a white cross you have to look close because there are several green pins which is what threw me off do this with all three plugs
