Replace T400 WXGA LCD with WXGA+ ?

Hi,

 

I recently purchased a T400 with a 14.1" WXGA LCD screen -- I would like to replace it with a 14.1" WXGA+ screen.  Has anyone done this before -- or know if it's possible?

 

Thanks.

You can easily change out the WXGA panel with a WXGA+ as long as you don't change it from a CCFL to a LED backlit panel. The LCD cable is the same for both the WXGA and WXGA+ panel CCFL baclit LCD.

 

If you want to change it out to a WXGA+ LED backlit LCD, you will also need it's respective LCD cable, as it is different than the cable for the CCFL backlit LCD.

Great links -- thanks for the quick response.  Is there an easy way to differentiate between CCFL and LED?  My specific model number is 6474 WZJ.

 

Also, can you switch a WXGA LED LCD to a WXGA+ LED LCD? 

 

Thanks agian.

You currently have a 14.1" WXGA, CCFL backlit LCD panel installed on your T400 as detailed here.

 

Currently there are no part numbers for the WXGA LED backlit panels, so I wouldn't know how to answer your second question.

Great, thanks again.  Does the link you posted explicitely say "CCFL" -- or is that noted by the lack of "LED" specification?

 

I will make sure that the replacement LCD I buy is a CCFL.

That is correct. The lack of "LED" specification indicates it is in fact a CCFL backlit panel.

 

If purchasing a replacement LCD panel on fleebay or the likes, I would highly suggest you make your purchase based on the FRU replacement part number.

 

Note: If you replace the LCD panel, you will void your warranty. Always keep this in mind.
