W800i Screen problem

Hello there. I have a W800i phone and i had its screen broken. so i ordered a new one which when i got it i saw that at the back of it had different codes than the original.

The original one had these codes: RNH942 29 R2C - G542G
The new one has these codes: RKH942 29 R3B - G618E

Is there a possibility that the new screen is not for this phone?

When i installed it it powers up white and no graphics are displayed. The phone starts normally though. I can do anything with the phone without being able to see, make calls etc. If the screen is for another phone can i make it work with this one without having to order a new one again?

Any suggestions? Thank you for your help and your time reading in advance.
