Wince head unit hangs on boot screen
 

Hi my wince head unit was all working fine radio, sat navigation, dvd, cd, music from sd card no problem. I took the unit out without disconnecting any leads to look at the connections behind to see if left could fit a reverse camera. All okay pushed unit back in screwed all back thought nothing about it then this.....
Switched on head unit boot screen appears the loading line at the bottom goes across as normal but when it gets to the end it just hangs there. Tried resetting, tried disconnecting battery, let removed the unit altogether checked all wiring replaced head unit still the same ll can't get passed the boot screen any ideas welcome https://uploads.tapatalk-cdn.com/201...086547116c.jpg
