The rebooting is not a good sign, or maybe it is.

Before opening the device and trying to repair anything, go ahead and reinstall the device OS. Maybe yours is the exception that proves the rule. Typically you just get the all white screen and everything else is working as it should, indicating just a hardware issue associated with the display. But your observation is different. The rebooting may be another hardware issue is involved, or it may be the white screen and the rebooting is a software issue.

Take the media card out, if you are using one. Test. If you still have trouble, reinstall the device software.

Repeat...don't try any repairs at this point. Test without the media card. If that doesn't work, reinstall the device software (reinstall the OS).
