Found out backlight in old screen is dead, ordering new one will this work for M15x?

Hi, I recently found out with the help of this forum, the backlight on my Alienware went kaput. I have a limited budget at the moment to replace the screen.

First question, does this seem like it's a good deal for the screen that's posted on this forum? Is it legit?
1080p RGB LCD screen B156HW01 V.7 WUXGA FHD laptop display EXACTfit V.4 V.6 NEW | eBay

Second question, if the above link is not legit, is this website legitimate and would this screen work in my M15x?

Laptop LCD Screen 15.6-inch WideScreen (13.6"x7.6") WUXGA (1920x1080) Full HD Glossy LED compatible with Alienware M15X 40 pin connector.

 

The link is good. From the pictures I've seen of an M15x screen, that one should work fine.

But, if you're willing to spend $10 more, here's a Dell OEM screen: Dell OEM Studio 1555 1557 1558 Alienware M15X FHD LED LCD Screen F790K B156HW01 | eBay

 

thanks m8 +rep

 

Not sure that will work for you dude. I believe you need to find a whole screen Assembly as the LCD panel is built into the bezel.

Edit: Something like this is what I think you need: Dell OEM Alienware M15X Complete LED LCD Screen FHD Black

shows otherwise.

 

More common than dead backlight is broken LCD cable that also brings power to the backlight. You might want to consider replacing that also (or first) since it's very cheap but requires as much labor as LCD panel replacement.

 

Yea but that takes some serious skill to do and you run the high risk of cracking the plexi glass if you arent carefull. If it were very very simple, id have an rgb screen in mine, but like i said before i dont wanna end up with a cracked screen.

 

Dell Alienware M15x LCD Front Bezel

If I crack the front. No big deal.

Also, if the LCD cable was the problem I wouldn't be getting a picture at all when placing a flashlight up to the screen right?

 

There's several wires inside the LCD cable for the picture and some more for the power. Only one of them needs to break and they are literally hair-thin.

The LCD cable itself is thick bunch of wires, if it goes at once you have been sabotaged

 

Sabotaged how?

 

are you positive the same cable going from the CCFL inverter to the MB is the same as the LCD cable?

 

Fujitsu Siemens Amilo A1645 (model sold around 2006) is the only one I know that has separate cables for LCD and inverter power. I'm pretty sure that there could be another model, but I haven't seen or heard about such in the last 10 years or so.

as in someone cut the cable... not probable

 

Ok, so what do I do? Worst case scenario it is confirmed the CCFL is blown or the inverter is bad, best case scenario I upgraded my screen, get a new cord and sell the OEM part on ebay? How do I test to see if it is indeed the cable?

 

Just when I think I'm out, they pull me back in!!! No all kidding aside, now I'm wondering do I pull the trigger on this screen, or test the same screen and deal with potentially the same issue again, what do I have to pull apart to test a new cord?

 

To replace the panel, you need to dismantle whole display assembly and unplug the LCD cable from it.

To replace the cable, you need to dismantle also the display assembly and some of the computers base too (I don't have access to Alienwares so I don't know exactly what).

Service manual, anyone?

 

like KLF was explaining you would have dismantle the display assembly for both, aswell as remove the touch control panel and keyboard first here is the sevice manual, and video teardowns of the process if it helps you out as well

and thanks for helping out here too KLF

thanks all Rep for those being helpful, very much appreciate it.

 

Cable replaced, screen is working again, though windows identifies it as a UPNP monitor is this normal? Thanks KLF, Still going to upgrade the screen at a later date!
