Dell XPS M1530 Display Problem

Got a Dell XPS M1530 that works fine mostly, except for the display. The problem I have is that whenever I connect a 15.4" display, it will not light up. If I hook up a 14.1" display, it lights up without any issue. I've tried with different displays and inverters, same result. Even used two different LCD cables to cover my bases.

Want to see what sort of ideas you all might have.

If you're talking about relacing the actual internal LCD, then there are a whole lot of things that could be going on:


1. Are you sure that the LCD itself isn't bad? Have you tried it on any other laptop?

2. Is it a Dell-branded 15.4" LCD for that exact laptop, or somewthing 3rd-party (or from a different laptop)?

3. If it's not the exact screen for that laptop, have you checked all the power requirements / refresh rate / resolution to make sure that it's compatible with your laptop?

Is the 15.4" display a widescreen display? And does your Dell have widescreen settings? The 14.1" display is likely standard 4:3 aspect ratio.

Is the issue unique to this display size? or is the more than one (4:3) screen that does not work?

Does the 15.4" display work on other machines?

It is a laptop, so the motherboard just may not be able to take the 15.4" display.

What I did not mention at the start of this... I have two different 15.4" displays that are known to be compatible with this exact model of laptop. The 14.1" displays I tried were from Dells as well.

Yes, the display is widescreen. And the screens have worked on other laptops, even though I will test them on other laptops again soon enough.

Is the screen pinching the wiring?

If the lid is to fit a 15" screen, then the same lid is not going to fit a 14" screen without some modification.

How did you interchange the screen size?  And then, did some wiring get damaged in the process?

Normally different screens require different lids.  ... Thinkpads_User

I'm doing my testing without the lid... it's a 15.4" laptop, but I tried a 14.1" screen just to see if the backlight would power up (one of those try the thing that shouldn't make sense type scenarios).

A netherworld I have not tried. Is it feasible there is enough power to run the smaller screen but insufficient power (age, hardware fault) to run the larger screen?

From a google search:

"XPS M1530 is at the time of writing only available with a single display version. It is a reflecting WXGA panel, called "UltraSharp CCFLdisplay with TrueLife" by the on-line configuration tool."

This is NOT an older machine as I surmised earlier.

Did you possibly damage the machine by trying a 14" screen from a different Dell model?

The power flowing out to the inverter would make sense. Things that make you go hmm....

I looked carefully at that machine and it is a very specialized display. That is why I asked.

For me in this case, i will try to change the Laptop's Screen resolution to the basic (800 x 600) , then try to connect to that 15" LCD. if it works, that mean some compatible issue between the laptop resolution and 15" LCD.

This DELL machine in question only comes with a 15" display screen, so there should not be a compatibility problem with the machine and the native screen. .... Thinkpads_User

There is no hard drive in the laptop, so any OS-related settings will not hold bearing.

So I had laid this down for a bit.... even worked on collecting ideas from others. The owners for three different local computer shops are intrigued by the issue and want to get their hands on the machine. Right now, I'm going to obtain another LCD cable since the one I have decided to start fraying.

Video to LCD stopped working... looks like I'll close this out. I will get the motherboard reflowed sometime soon, which is a hardware issue in and of itself remember the famous flawed nvidia chips!) Thanks all!
