Electronics Another monitor prob...

I have a 15" monitor that sometimes goes blank and it has a line of image light going across it up the top of the screen and i have to pull the monitor forward to get the screen to display fully again. Now it has fully gone black and i dont know whats wrong

Can someone guess whats might have had happened to it?

Ps it's good monitor and i poor to buy new one.

 

I'd say it's dead, check it on a another computer to rule out the graphics card.

 

Maybe the cable's been damaged, if you wiggle it around at the back does it change what the monitor's displaying?

 

yeah like the cable at the back of the monitor that connects to the video card, when i jiggle it around it does a bit like makes the screen flicker....

 

Do you have another you can try instead? Hopefully it is the kind that can be replaced, and not the type that connects directly into the monitor.

 

This happened to one of my monitors- check where it attaches to the monitor and right at the base of the plug-the two spots where the cable is least flexible. Mine got screwed up right there at the base, and I would lose all the colors in my monitor if it jiggled wrong. Unfortunately, I was unable to do anything whatsoever to remedy the problem. However, getting a replacement 15" CRT shouldnt be much of a problem at all-although it's prob more difficult to get stuff over there in Kiwi County

 

AHHH it's dead i think

 

I'd say dead, my old one died out like that.. well.. one day I was playing CS on it, the next day.. the screen would turn on, but just be black... check all the cables and everything, even got a new one.. still didn't work.. it was time to get a new one!

 

The vertical sweep generator is screwed up.


Essentially, a monitor uses a couple of big electromagnets to sweep the electron beams across the phosphors on the inside of the surface of the screen. Something in the electronics that drives the vertical sweep generator and accompanying electomagnets has died or failed.

Whether it is fixable depends on you level of electronic competence, and what specific part it is that failed.

 

Sounds a bit harsh, but if you're going to replace it anyway.. try giving it a good whack on the side (I've one that's been doing that for about a year, now & again a subtle impact seems to help).

 

the trouble with when monitors crap out is that you cant post on bit tech to ask what you can do to fix it, unless you have another monitor lying around.
