Help my monitor has stirpes

[xodarap]

I woke up this morning and my BTC monitor had decided it whated to be a zebra everywhere their is black the computer leaves a long grey streak across the page. What happened! what do i do about it?

 

[sohcrates]

i once thought my monitor was shot, but i pulled the power on it and let it sit there for a while to think about what it had done (and also to reset itself) and when i plugged it back in everything was happy again. now, my symptoms were nothing like your problem, but it's definitely worth a shot. i'd say keep it unplugged for like 10 minutes or so

 

[xodarap]

That sounds way to easy! but ill try it

 

[sohcrates]

i know it seems silly, but it would be REALLY silly to overlook trying this.

if it works, then great! if not, well, at least you can cross this idea off your troubleshooting list!

 

[xodarap]

nope

Have you plugged or unplugged your monitor before you started having problems??? Sometimes you can get this if the pins are bent on the video connector. Do you actually get some sort of a picture when you turn it on? It kind of sounds like a dead main deflection board (time to get a new monitor). Also if you are getting a picture you mey be getting interference from a fan or light or some other power source. Try turning off anything that uses power around your computer. Also try a different refresh rate.

If you can, borrow a monitor to try. That will narrow it down to either monitor is bad or vid card is shot.

 

[xodarap]

thanks lord sandman good idea emjem

 

[xodarap]

The pins are good changing the refresh doesn't help, Im afraid my refrigirator magnets masy have been to close can that be fixed?

 

[sohcrates]

does your monitor have a degauss button? if so, that's your best bet if you think it's been subjected to a magnetic field. although, i wouldn't imagine a refrigerator magnet would be strong enough to screw it up , and the symptoms you describe don't sound like a magnetic issue, but....

 

[xodarap]

I tried deguass what else you got?

 

[LordSandMan]

Try deguassing multiple times. Up to 5. If that doesn't work, your last chance is to use a deguassing coil. Most Computer companies bigger than 3 techs should have one. If you have to buy one I think they're around $100. I've got one but your probably not from Minnesota.:frown:


Edit- hmmm, are you sure that it was the magnets??? Magnets usually cause discoloration, but not stripes (though it is possible).

A bad connector usually causes either smearing to the right of each feature (each character will look smeared) or quick flashes on the screen, usually affecting one whole color (picture becomes tinted). What you describe seems like either the degaussing is stuck on (but you should see rainbows, not just black or grey), something wrong with the picture tube (shadow mask - degaussing may help, but it may have shifted), the internal power supply has done bad, or there's something near the monitor causing interference (speaker).

You can check for the degaussing being stuck on by temporarily disable the degaussing coil, but don't do this unless you know how to avoid electrocution. Turn off and unplug the monitor from everything. Inside, around the front of the picture tube, will be the degaussing coil. It may be wrapped in electrical tape or a vinyl covering. Two wires lead from it to a circuit board, and unplug it from the board. Reinstall the back of the monitor, and if the rainbows are now gone, you know that the degaussing control circuit has something wrong with it, probably a bad relay or transistor driving the relay.

<< Try deguassing multiple times. Up to 5. >>



Been thier done that



<< Edit- hmmm, are you sure that it was the magnets??? Magnets usually cause discoloration, but not stripes (though it is possible). >>



Im hoping it wasn't the magnets im sort of broke



<< A bad connector usually causes either smearing to the right of each feature (each character will look smeared) or quick flashes on the screen, usually affecting one whole color (picture becomes tinted). >>



Thats sort of what its like, no tint but anything black gets smeared across to the right and left



<< What you describe seems like either the degaussing is stuck on (but you should see rainbows, not just black or grey), >>



Thats sound interesting, at the farright their is this bright yellow shine at the end of each smear

Wow Cool! I got to try this...

 

[LordSandMan]

hmmm, it's really starting to sound like main deflection board. Did anything change when you remove the magnets???? How close were the magnets???? If the stripes didn't change at all when you moved the magnets I think the board is toast.

Hi Xodarap,
I think I had the exact same problem this weekend. All of a sudden the black on my screen was bleeding and striping across my monitor. I switched video cards and unfortunately, it was my video card. My 3d prophet (geforce ddr) fan had died a couple months ago and I replaced it with a crappy cpu fan. I suspect that the heat was the culprit because when I took it out, it was very hot to touch. I confirmed that it was the video card by putting it into my second PC and having the same results. I decided to go buy a new video card. I am definitely leaning towards your video card dying after my recent experience...
Can you try a different video card or try your video card in a different computer?

Good Luck!

Lodsand Man-yeah i moved the magnets and nothing happened they were about 2 feet away

Rockstar-Wow I think we got a winner, you spec sheets for you comp (if i put back your old graphic card) mirror mine down to within a hundred Mhz, Ive had this think running 24 hrs for a month so i wouldn't be supprised if the fan crashed...I hope not but that is definately a possibility.

 

[LordSandMan]

well, 2 feet and they were just kitchen magnets??? you can rule the magnets out as the cause (if they were bigger than cow magnets you might have a different story). I didn't even think about the video card. That could very well be the problem too.

 

[SnoopCat]

someone had the same problem with green stripes, it was the video card.

 

[blues008]

it's the video card.
happened to me last week.
