Keypad lights won't go out

[Guest Wouter85]

Hello everybody,

This is my first post and I have used the search function first. I've got a HTC S710 (vox) which was working fine until Sunday. Since then the keypad lights won't go out (display goes out). I already tried the registry hack, did twice a hard reset,...but the lights won't go out. If anyone knows the solution please let me know, it's not fun to reload the battery every evening.

Thanks in advance
