DELL E6500 SCREEN

Hello

I've got a dell latitude E6500 but the screen doesn't work anymore. It's a AU optronics B154PW04 version 1 (WXGA+  LED, 1400*900)

I've bought a LP154WP2-TLC2. When the laptop starts, the screen is on but it remains black...is it a problem of compatibility?

I plan to buy a B154PW04 but version 3. Does anyone know if it's compatible with my laptop?

Great thanks
