Need a Philips LED driver for laptop screen replacement

March 18, 2013 at 07:13:45
Specs: Windows 7, Pentium M Dothan, 1.86GHZ / 3GB Ram
I just replaced a broken screen on a Dell Vostro 3700 running Windows 7 32-bit with a LP173WD1-TLA1 (apparently Philips is the mfgr) purchased on Ebay. When it boots up I can see the Dell logo and the subsequent Starting Windows animation, after that the screen goes black (the Windows logon prompt is what should be on the screen at this point). You can see the backlight lit up and 1 dead pixel, but that's about it. If you plug in an external display you can clearly see that you are at the Windows prompt and can proceed from there. Rebooting into Safe Mode will give you a working screen as well. In device manager it's detecting a generic PnP monitor. I tried updating it but it says the best driver is already installed. The seller wasn't very much help in providing a driver source for the new monitor/screen, so I am forced to hit the forums. I have Googled the h3ll out of the part # all weekend to no avail. Any relevant help you can provide will be greatly appreciated.

Screens don't need special drivers, the drivers are included in Windows - Windows has already told you have the best driver installed. If you can get into safe mode using the new screen but cannot a display in normal mode, the problem might be the screen resolution setting. Are you sure this screen supports the same resolution as the original? Is it set to 1600x900 or lower?

Try tapping F8 at startup, then select "enable low resolution"

When I plug in an external Samsung SyncMaster 743BX, it shows that way in device manager, not as a generic pnp.
(Windows often gives an error message of some sort that isn't entirely true.)
I did try all available screen resolutions, none of them give me a viewable screen.
Hitting F8 only gives me Safe Mode options.

Yes, the screen does work in Safe Mode.

When in safe mode is more than one display listed?

Was the screen you purchased guaranteed 100% compatible with your laptop?

The listing as generic PnP display doesn't necessarily mean the display is not being properly configured by Windows.

I recommend you go to the link below. Enter your service tag number and then download the correct video drivers for your unit.

More than one display is listed only if I have an external monitor connected at that time, otherwise, no, just the one.

The company http://rover.ebay.com/rover/0/e1105...

said that the screen is compatible.

One of the first places I went to was Dell's site after popping in the ST #. I used their 'outdated' videocard driver, rebooted, changed resolution settings, then went to Nvidia's website, downloaded their latest and greatest drivers for the videocard, same issue.

When entering the service tag, did you see only one video driver available for your exact unit?

Post the service tag.

BC007N1. Just one for the Windows 7 32 bit OS.

Look at the two links below. The first may apply to your configuration. The second is just an Intel chip set update that may help.

I tried your suggestions, thank you very much for your diligence, but it shouldn't be this hard for a replacement screen to work. I am going to return it to the manufacturer on eBay.

You are probably correct. I just thought you should try all the possible solutions.

The Intel chipset drivers may enhance performance. Otherwise, why would there be an update?

The Dell monitor file seems to indicate there is a need in some cases for it. Neither can hurt and if they solve your problem that is easier than tearing the laptop apart again.
