Change the screen on a GO 520 530 720 730 920 930
I changed my screen tomtom samsung LTE430WQ by Sharp.
I found the screen decalé 1cm to the right (not complete).
To remedy the problem:
1 - Remove the 4 screws on the motherboard.
2 - remove the original samsung screen broken or problem.
3 - connect the new desktop sharp or samsung
4 - Remove the battery connector for 30 seconds.
5 - reconnect battery
6 - switch your tomtom, the image is now entirely on the entire screen.
