A full white screen means the backlight is on. Is the ribbon cable all the way in?
Red wire has to be on the left most pin. On the picture it's connected to the second pin which is ground.
The wire connected to the chip should also be on the left most pin.

Also, even though it's a bit too late for that now; did you check if the screen worked without modification?
And also if it didn't, did you try the second method?

If the board is broken I have one for you as I broke my screen yesterday.

What i also notice is that the pcb's are getting very hot also the pi.
Im new to all of this so dont know if its normal

Which wire is connected to the TV pin on the Pi?
It would be helpful to have a picture showing both the screen and pi connections to get an overview.

I saw that, I meant a photo of how you connected your Pi to the screen.

Thanks, that helps! What are those black circles on the Pi connections?
That looks a bit troubling. Do you have a multimeter to check the different connections?

The one with the sound wave on your multimeter is at the left (200).
If you need more info google; testing continuity multimeter.
Good luck!
