Vertical line on monitor--solution?

My neighbor's PC monitor had a single vertical line the full length of the left side of the screen (in the area where most icons are arranged). Over time, it appears to have gotten a little thicker. It's different colors at different times. She says it doesn't bother her, so should we just ignore it, or will it get worse? The monitor is less than three years old.

Panel is failing. It'll work its way over time, no way to pinpoint how long until it is really an issue.

There's the coax and rub the pixels method back to life but it's a crapshoot. Either it gets slightly better, nothing happens, or it gets worse (usually happens for me).

LCD's are pretty cheap these days new and especially second hand. Both the economy and that lawsuit against the panel makers dropped the prices significantly.

Edit: If it's still under warranty might want to check it. Usual 1 or 3 yr depending on mfg.

none. it's permanent damage.

ask if she frequently keeps monitor on for a long period of time.

I know the answer to that question. She doesn't use her PC much at all, and she turns it only when she's using it. Maybe one hour per day? She uses her iPad for checking email.

hhhhmmmmm.....

1. if the monitor is between speakers... that might be it - an electrical interference
2. give it a tap here n' there and then hope for best?
3. press the default button (or similar - some kind of reset) on monitor
4. adjust Display Properties especially Refresh Rate. If nada, then try changing resolution.

if nada.... then it's physically broken and since it's not bothering her, then leave it alone

there's a small chance that the monitor could be damaged from power outage even if it was off but it's still connected to power outlet. in case of storm, it's best to remove all plugs. the power outage damaged my HDTV bulb twice even though it was connected to expensive power surge protector. A $200 problem.

plug it in to another computer or laptop / something with vga out if you want 100% confirmation it's the monitor. No need for arbitrary dabbling.

Curious, is the monitor a Dell? I'm finding (at work) several Dell monitors are starting to show the vertical line down the screen as well.

I know I had a problem like that, but it was a moving line and we founds out that it's my cell phone being too close. Once I move my cell phone, it goes away.

Only problem to CRT only. Should not happen to any LCD types.



This is CRT.

Only happen to CRT. Nothing happen with LCD. There is some LCD with built-in speaker and nothing happen.

No, not that bad.

So far, it's only one line (or maybe a few skinny lines together), about 1/8-inch thick, on the left side. Similar to that red line on the far left of your image.

Yeah I know it's not that bad, just to get an idea for some people in here. I know it can happen to LCD monitors. I've seen the ones that cover the whole LCD and you can't see anything at all. Some even show half black and half with video, that looked odd.

They say it's possibility a bad video driver or the bad monitor itself. Best way is to take that monitor and plug it to your computer to see if it still displays that then it's the monitor. If it doesn't bother her then no worries.

I would say it's time to replace those monitors!

Do you still see few skinny lines since boot up? If so then it's bad flex cable from LCD.

Or only happen in Windows? If so then it's bad driver or bad GPU from computer.

The owner turns her computer on in the morning--the line is there. She checks email, makes a couple copies, scans a photo, done. She turns off the computer. She does the same thing later in the afternoon or evening. Line is there. Turns off computer for the night.

She doesn't use her computer often but when she does, the line is there. She says she doesn't notice it unless I mention it.

I think it's my fault for pointing it out.

Umm no. I apart to LCD with built-in speaker before and there is no protection.

No trolls please.

My father have two big ass speakers between his LCD and nothing happen for over 10 years.

I just googled it for you due your ego problem.

Quote:
LCDs are not affected by magnetic fields like the old CRT (picture tube) sets were. The magnet in the speaker will not do any harm to an LCD.

If your first set was LCD, any failure in your old set most probably had nothing to do with speaker placement.

I hope this helps. Please return ans select a Best Answer from all of those submitted.

LOL, No worry about that. Some people have same problem and it's normal and easy to ignored.

protection may not be needed if the manufacturer found the right speakers with right specification that will not cause interference. That's why most of LCD speakers sound terrible.

and I just googled it for you due to your stubbornness

Not as much as CRT TVs, but it can cause patterning.
Quote:
No as much as it does to the normal CRT. (normal television with a picture tube).
I will all ways advice to keep speakers away from any other electronic Equ. specially if the speaker magnet is not protected, but now days almost all speakers have a protection case in order to avoid spillage of the magnetic field.
you are not an engineer and I went to engineering school for 3 years so yea I do know a thing or two about interference. Again - you never know but things do happen. It's not just a magnetic interference but electrical interference.

and since your father is an engineer... he probably got the speakers with shield.

It's do nothing with lines problem. The electrical interference cause lines problem? I don't believe it. Should cause LCD screen in "wave" but stuck lines? um no.

The speakers is 15 years old and I don't think it come with shield.

I am not an engineer but I can fixed everything like I used technician from Canon for seven years and I knew what's problem it was and I can fix right away. There was a lot LCDs with lines problem due flex cable plug weak or poor soldering job. So I fixed by re-soldering or replaced a new flex cable.

The engineering school is nothing to me. You are not even engineer experience for real job for over 5 years. I prefer listen real experience over student. That's why most jobs want people with job experience over student.

Again, your link is do nothing with electrical interference but magnetic interference. So you won't admit you was wrong.

bop bop bop!

btw - I did engineering jobs at university's Aerospace & Ocean engineering lab, satellite, and manufacturing shop

Experience doesn't mean shit to me if they cannot explain the technical reason of any problem. "oh yea that causes this... but I dunno exactly why but all I gotta do is put the tape on it and it works just fine." rrrriiigghhhttttt There's a reason why some people are called technicians and some are called engineers.

a good engineer always check out everything even a very unlikely issue. if it ain't magnetic or electrical interference for sure.. then cross it off the list. simple as that. that's a good example of being thorough.

And your engineering is do nothing with LCD. You barking at wrong tree. I already know what's reason and causes problem. Again, I already explained. Thanks you so much.

Only bad engineer thought speakers cause LCD lines problem. due no experience but just guess.

no you didn't explain. Yahoo Group did

and beside... if you already know cause, then why isn't it fixed?

Look back and you'll see that I listed several culprits.
