Reseat the flex cable to the display (inside the system). If that doesn't fix the problem, replace the cable, and if that doesn't cure it, repair or replace the display panel.
I have a new Vostro 1510 with the same issue. A lot of macbook pro users had a similar problem a couple of years ago, the only solution was a replacement panel.
WUXGA panel on mine.
One thing I have discovered is that if you have an option to drive the display using less power (nvidia drivers have the option) then the problem is marginally less noticable, but still apparent. Unfortunately this option causes a strobing flicker, like shadows or waves up the left of the screen, more noticable on darker colours like grey or blue (but not black), due to the florescent tube being underpowered.
Just like you, I've done all the tests. External display is fine. It's not related to the inversion scheme used on the screen either, as other screens with that type do not display the effect.
The problem is not as prominent toward the top of my screen, more proof that it's just a manufacturing defect as opposed to a software issue.
After I did everything possible to narrow down the problem to the screen itself (external monitor, macro pixel photograph, varied res, generic linux boot, etc etc) I contacted Dell support and they sent a technician with a replacement panel. The backlighting bleeds a little more on this one but it's the same model, the LPL (LG phillips) 3e01 and yes, the probelm is present on this one, too. Interestingly, the horizontal lines are once again more prominent the lower on the screen you go and the top 10% is not visibly affected.
The tech took note of the test images I showed him, etc, and contacted Dell whilst he was here on-site. Dell are replacing the mainboard tomorrow. From the research I've done, and all the information available from when the macbook pros had exactly the same problem in 2006, I don't expect this to make any difference at all - it's an LCD panel design/manufacture defect as far as all the evidence shows so far. I think the problem will persist once the mainboard has been replaced and if that's the case I'm going to try for a different brand of panel. The problem with that is that the tech I spoke to wasn't aware of any other brands being used in the vostro at the moment - a bit worrying but we'll cross that bridge when we come to it.
One thing must be said; although I'm not happy with the screen I can't say a single bad word about the service so far. The maximum time I've spent on hold has been three minutes (impressive). Every time I've needed an engineer, Dell have sent one to my house on the next working day - and they even phone on the day itself to let you know when they'll arrive. Hopefully this issue will be resolved one way or another soon, but even if the product is defective, the technical service team certainly gets top marks.
As predicted, the motherboard replacement made no difference, except this mainboard runs hotter due to an inferior aluminium cooling system instead of the copper on my original board, AND that the bios on this mainboard is not updated to take into account the updated keyboard my vostro came with, the upshot of this is that I press z and nothing happens, I press x and it types c, c gives me a v and so on. I contacted dell within minutes of the technician leaving and they referred me to a special department to obtain the special bios update, no phone number, email only. I sent two emails now asking them to email me the bios and no reply, so that's two days now I've been with a unusable keyboard. Not only was the technician visit a waste of time but he's caused problems instead of fixing them. I'm getting quite unhappy now.
Dell shipped another bios, which didn't fix the keyboard issue, even though it did update to A06.
Once this was reported, Dell very promptly shipped out an entire replacement vostro (top marks again).
However, I'm sorry to say that the screen problem is present here, too.
So that's a total of 4 different panels (all LG-Philips - model LPL154WU1(lt)(a2)) all with the same issue.
It's very obviously either a batch issue affecting a production run of these screens, or a design flaw affecting them ALL.
Don't get me wrong, the speed of Dell's response in sending out engineers, etc has been top notch, but the quality control on the other hand leaves something to be desired.
This particular LCD issue arose before in 2006, affecting various Laptop manufacturers, including Dell, but particularly affecting Apple. The defect presented in the same way but the affected panels that year were all Samsung screens, a specific model number. Affected customers found that using an LG panel as a replacement solved everything. Now it looks like it's the other way around.
This to me suggests that one particular method of manufacturing LCD screens results in this sub-par quality, but must be cheaper to do. Many people with imperfect vision won't even notice the problem, and if it saves the manufacturer a handful of dollars per panel, they can handle the small volume of returns and still be better off than if they'd built the screens to spec in the first place.
Dell assure me there are no other brands of LCD panel used in the Vostro so it looks like there's no resolution to this and anyone who wants a 15.4 WUXGA screen should be looking elsewhere.
I'm certainly not happy paying extra for a high-dpi screen only to find it's useless for close work, photographs, etc.
I'm currently debating whether to negotiate the return of the screen upgrade fee or simply to reject the laptop altogether, and buy a laptop with a decent screen instead. It's a shame that 15.4 wuxga offerings are so thin on the ground from other manufacturers, but an even bigger shame that I might now be forced to buy something other than a Dell, whose computers I have repeatedly bought and recommended in preference to other brands, partially because of the good service (and all through this the service has been excellent bar the mainboard/keyboard issue) and partially because of the solid quality.
I like the vostro, I just wish Dell hadn't taken the decision to cut costs with this bargain-basement substandard LCD screen panel - it ruins an otherwise very nice machine.
AM having a similar issue : Lots of horizontal lines on screen. i connected the external VGA port to a monitor and it works fine. according to what i understood from other users on this forum, it is the screen which need replacement. Right?
Where can i find genuine replacement screen for the Vostro 1510.
Appreciate the effort that you took to troubleshoot the issue. There are a couple of steps that can be tried which would help us drill down the issue.
1. Run the LCD Built-In Self-Test (BIST). 2. Test the LCD in the System Setup (BIOS).
If you observe the same issue on the setup screen or during the LCD Bist, it is a hardware issue and the LCD needs a replacemnet. For more details please check the article on Resolving Laptop LCD Lines, Fuzzy, Color, or Blurry Issues.
Does the computer have an active warranty? You can check the warranty status here. In case of expired warranty scenario, we would not be able to extend warranty entitled services. If the warranty on the computer has expired, you may contact our Expired Warranty Services (this is for US based customers).
Please write back if you have any further questions.
Thank you for replying. Since you have already tried connecting an external monitor to the computer, and have mentioned that it works fine but the laptop LCD has the horizontal lines. Along with that the error code also proves that the LCD needs a replacement.
As you have mentioned that the computer does not have an active warranty, I would suggest you to contact our Expired Warranty Services (this is for US based customers) to get the LCD replaced.
Please write back if you have any further questions.
moreover it may be all the lcd parts is working and the lcd connector on the motherboard which might be faulty. ( in this case, this cannot be repair - a motherboard replacement is required) "
In order to assist you further, I would like to know which country are you in. So that I can check the options to the get the system repaired for that country.
am from Mauritius. according to record one authorised representative is Harell Mallac. However labor cost will be expensive .If the fault is the LCD, I would like to replace it myself as i have all my documents and cannot leave it for several days at workshop.
I asked the reseller technician he told me "

According to your experience and the printscreen provided, how far the LCD connector is more likely to be damaged rather than the LCD.
Please click here to contact the Dell authorized Service Providers in Mauritius. Regarding the issue, I would like to say, without replacing the LCD, ask a local tech to connect a similar kind of an LCD to the system and check if that works. This would prove the functionality of the motherboard and the LCD. If the other LCD works fine, then the original LCD needs to be replaced.

Hello Dell-Allan
Thank you very much for quick response. I really like that.
1. I have performed the LCD BIST test and got the error 2000 - 0334.
2. Cannot Enter BIOS. i.e dark screen which becomes white gradually.
Picture below refers.
Warranty is over. After 4 years of satisfactory usage am having this issue.
just hope i will get a solution very soon as all my files are on the laptop.
Thank you very much
