    Bad Screen or Bad VGA Cable?

    I have a Sager NP9260 w/ a cracked WXGA+ screen. I bought a WUXGA+ screen from a Clevo M570RU. Everything installed smoothly (had to switch out the metal side brackets, but otherwise easy enough). Fired the laptop on and it gave me a really wierd background screen that flashed. I reinstalled the old screen and the display looked fine (minus the crack). Upon closer inspection of the vga cable I see there is a missing metal pin. If the pin is active then I can see this being the problem, but there are more pins on the connector than there are wires going to the connector (so there must be some pins not being used). Anyways here's a picture of what the display looks like and a picture of my vga cable. If it's a bad vga cable then I can replace that for about $9-$10 on ebay. If it's a bad screen then I'll have to return it back to the guy I bought it from. Any help is much appreciated!

    Whoa!

    Let us elaborate on the bold comment first!

    Here is the screen in question right before you purchase it, notice it is working great!

    Now if your VGA cable is missing anything that is suppose to be there, then that's where the problem lies. Judging from that picture you posted, there is definitely some kind of connection problem going on. It would be nice if you showed us the old display and its connection, that would help tremendously.

    It does not sound like a bad screen, but you have to realize that with the different resolution screens, you DO have to use a different cable that goes from the motherboard to the screen (it means a [at least partial] tear-down to get to it, and replace it); well 90% of the time you do from what I know about it all

    Is the cable exactly the same size as the connector on the new screen? or is it slightly differently sized?

    I'm short on patience, people should know that by now. I surely can't stand to be questioned about something that was working brilliantly prior to shipping.

    Mr Luke!

    Send me back my screen in the same condition I sent it to you, I will just deduct my shipping and shipping material, thanks!

    bold comment? I'm just asking a question (if anyone has ever come across a problem like this before). I never blamed you or the screen. I mentioned that I thought the problem lied within the vga cable. But a bad screen could be a slight possibility (a bubble mailer probably isn't the best shipping option for a screen).

    The connection on the old screen is the same as the new screen (the cable locked in just as it should).

    Don't know where you got that information. Each laptop has only 1 vga cable that is used (you don't have to purchase a different cable for a different resolution screen). I use to replace Dell Inspiron E1705 and the Gateway FX laptop screens all the time (upgrading them from WXGA+ to WUXGA+), so unless something has changed in 3 years that isn't the issue.

    uhh... Is english your first language? I really don't understand where you're coming from here unless you are just misunderstanding me? I am not blaming you at all. I never even mentioned you as the seller. I still think it's a bad vga cable, but I won't know this until I get a new cable later this week. If it is a bad screen, then it very well could have happened durring shipping (mix USPS w/ a bubble mailer and you are just asking for trouble).

    I don't know if that was a question or not, but to answer it; no, English is not my first language!

    I'm just a little pissed off right now, to put it mildly. First I wait on feedback from the video card, only to find out later that the guy doesn't know how to install the card. Secondly, I wait on feedback from the processor and screen, only to come across a thread like this one. I know, you linked me to this thread. But still...

    I need to rest, I'm having a hard enough time now finishing high school. :(

    ok, you're right. It looks like there's different cables for each screen type (WXGA+, WSXGA+, & WUXGA+). Can't find the WUXGA+ cable for my D9C, so I bought a D9T WUXGA+ cable that looks similar (hopefully it works, otherwise I wasted $15 for the cable).

    On my Dell Studio 1558 w/ ATI HD 5470 graphics, there are definitely different cables for different screen resolutions. And it isn't a case of different part numbers on the same cable - they are wired very differently:

    There's lots more info on the screen swap on my blog.

    Is that with the integrated graphics, or ATI?

    The 2 cable pics I posted were from 720p and 1080p panels. I confirmed it by opening 1558's that were shipped with those panels, and the cables were different. When I upgraded the 720p 1558 to 1080p, I had to swap the cable for it to work.

    There are actually 3 display cable part numbers for the 1558, but the 3rd one doesn't have the extra leg that connects to the built-in webcam, so it seems to be for a stripped-down model.

    Dell seems to have gone crazy with removing wiring for things that weren't ordered on the 1558 - there are a huge number of different lids with different numbers of antennas installed. More about this on my blog.
