any other d900c users have a verticle halo line on lcd?

towards the left side there is a slight verticle halo line running the full length of the lcd scren. it is about a 1/4" in width and mostly visible in a greyish background. if i change resolution i can see it quite clearly when the screens goes blank and attempts to come back. during that split second that halo line is actually darker that the rest of the screen. it appears to be hardware related and not software as drivers and sli on/off does not appear to have an impact.

my screen does not have any dead pixels, just this halo line. anyone else experience this on their d900c? maybe it is because there are dual gpu's or something.

 

That really sounds like a hardware problem; are you still within warranty?

 

yes still under warranty.

going to hate being without a laptop for two weeks. i hope warranty covers lcd defects (other than dead pixels) like the rest of the system. i must have had this defect since i got the machine but did not pay alot of attention to it.

 

I think that one or two other owners have had similar problems with horizontal lines running across the screen. In each case, I believe that it had to do with the LCD ribbon cable being crimped or otherwise damaged, or having come loose. If you're adventurous and don't mind opening the thing up, you might check to see if that cable's gotten damaged.

 

Turn the notebook off and restart it then repeatedly press the F2 key in order to get into the BIOS. Is the line present in the BIOS?

If so that would most likely be a physical issue as the other posts have said. Contact your tech support.

 

i'll check that that.

i am so lazy now it's one of those days.

 

the halo line is very very faint and i cannot tell by browsing this forum. but if i go to other sites that use greys and blues or darker colors it is noticable.

 

I had a simliar problem, with ghosting white lines appearing horizontally on the screen. Sometimes my windows desktop would also get a little... weird, etc. I sent it in, had the LCD cable replaced and the problem went away.. for a while. The problem has started up again just recently; the only thing I can think of is that they just "reset" the cable instead of replacing it, or the cable just is a piece of junk and needs to be replaced again. I can make it go away by moving the lcd back and forth just a bit or tapping the plastic piece to the left of the indicator lights [the harddrive, caps lock, etc.] so it is definitely a hardware issue for me. You can try the tapping thing if you want

 

i opened her up and reset the lcd cables connecting to the motherboard and that did not do anything. i can see the halo line in the bios, although the colors of the bios make is very very dificult to spot. i then noticed that you can easily see if you have this issue by simply restarting the system during it's attempt to boot up before it even reaches the diagnostic screen by pressing ctrl-alt-del. when you do that the lcd light comes on and off and i can clearly tell that all but that faint verticle halo line will light up during that split second.

 

That is almost certainly a mechanical defect in the LCD unit itself, not a software issue. Time for an RMA.

 

yup. i hope they will still honor a replacement lcd with no dead pixels since i initially paid for it. it could be a sticking point because they do not honor dead pixels after 30 days laps, but this is not a dead pixel issue. i would rather deal with the slight halo than dead pixels.

 

I had a halo on my old screen. It was a mechanical defect. However, I've seen similar phenomenon from physical damage (not intentional) from when the screen was pressed on from the outside. LCD panels are very fragile, given the fact that there is liquid present underneath glass.

 

This isn't a dead pixel issue, this is a gross mechanical defect; just be sure that you didn't accidentally cause it yourself, as the poster immediately before me pointed out that it can also be caused by overstressing the lid of the notebook.

 

where did you buy your laptop from?

 

i bought it from sager directly.

 

ARGH: If the line is 1/4" wide, and is vertical, running the entire height... is it also about an inch from the left side of the screen?

There were some drivers in my 20.1" Assassin (through nVidia control panel) where you enable SLi that allowed you to click a check box and visually Show GPU load balancing. It was a feint green bar that sounds strangely like what you are describing.

I hope that is what it is because clicking a check box is a whole lot more desirable than fighting for a new screen. If you need a new screen, contact me if they are going to hork you around on the replacement parts prices.

 

OK, I dug up an old Quatro 2500 Sli configuration video I made for my customers and got a screen shot of the setting I am talking about. The Quadro cards won't make any difference, it will be a setting. Granted this is on an older nVidia control panel, but worth a shot. This is what I am hoping it is for you.

​

What I am thinking about looks like this:

​

 

If you do have load balancing enabled then it will be pretty prominant.

There are occasionally issues with the screens but it's very rare, I know we had a couple that if you looked at them at 80 drgrees from head on there was a band vertically about 4 inches wide on side. At this angle it showed a dark grey and not black but as said previously if it appears in the BIOS and Windows then it looks like hardware, if just in Windows then put your wallpaper to full black and see if it's more noticeable.

Best to contact the manufacturer directly though as they'll be able to sort it out and deal with the warranty etc.

 

I am just hoping that is what it is.

The 1/4" wide band is what is throwing me here. I have seen colored lines down the screen before when it has gone bad, but never that large.

If you have to send this thing back please document the saga on the forum. Then contact me if you have to buy a new screen.

 

here i took these photos of the symptom. one showing it on a web page and the other during a boot cycle when the screen blinks on and off you can tell it's there. on soime colors it is not noticible. browsing this website i cannot tell the line is there.

 

killernotebooks i do have warranty (3 year extended warranty directly with sager) i just do not know if they will honor a new screen with no dead pixel gaurantee (since this is not a dead pixel issue), as i originally purchased that as well.

 

That sucks (referring to pictures of problem), it's not what I was hoping.
Sometimes you can hope that it is the $10 LCD inverter, but in this case, I don't we're going to be that lucky.

I am going to make a ruling here that it is a screen defect and should be covered under the three year warranty. Of course, I have no authority here, so that means nothing, but that is clearly NOT a dead pixel issue. IDEA: If they don't cover it... ask for the 3 year warranty premium back to put some pressure on them. It may help, maybe not.

I re-read your post. I am unaware of what their policies or NDP guaranty's are. Are you saying that you paid for a no-dead pixel guaranty (which is like $200) and it is only for 30 days or that you just get 30 days of NDP?

I put 30 days on mine in the warranty section, but honestly, that is only so if someone is a total jerk I can point to it and say, "Sorry." 99.99% of my customers are totally cool so it is really a year.

 

yes their NDP is basically purchasing insurance for 30 days from moment of sale gauranteeing no dead pixels. if dead pixels show up after 30 days then it's no longer covered under the NDP.

i know this lcd defect is covered under warranty. i just do not know if they will replace the screen with their NDP in effect. in other words, i do not want them to replace the screen with another one that has dead pixels since i paid the NDP at time of purchase. if i was complaining about dead pixels arrising after the 30 days NDP i would not have a valid point as that is clearly stated in their terms. but since this is not dead pixel-related i am hoping their lcd replacement will be tested for no dead pixels.

 

I recommend contacting your seller and they will surely help get this resolved.

 

yup, i'll contact them next week

 

Keep us posted, and I'm sure having an active forum thread will not hinder your chances at a favorable resolution ( if you know what I mean)
