Screen upgrade on toshiba tecra m5

Hello to everyone!
This is my first post and I come straight away with a question
I have an old Toshiba Tecra M5 laptop wich has some screen problems (flickering, almost no backlight).
So I bought another Tecra M5 (with a broken motherboard but a working screen) on Ebay.
Now I realised that there are a lot of Tecra M5 with different specs (ok, I'm definitely a laptop noob).
So now I have:
Old Tecra:
-Intel Core 2 Duo T5600 1.83 GHz
-Mobile Intel 945GM Express
-xga screen (semibroken)

Newer Tecra:
-Intel Core 2 Duo T7200 / 2 GHz
-Mobile Intel 945PM Express
-sxga screen

I already tried to connect the sxga screen to the old Tecra: it does turn on but no image is displayed.
Then I tried the old display with the new inverter (exact same model) but sadly the inverter is not the problem.
Can I somehow replace that display? maybe by swapping other parts too.
Thank you,
Teddy

 

This is easy and shouldn't take you more than an hour and a half to do the first time plus you get a decent upgrade by using the t7200 in the working board.
