I have a HTC Tilt 2 and the backlight in my screen does not work. When I power the device on the backlight would come on and the screen would be working perfectly but when it goes in hibernation mode or i press the power button for it to go in hibernation mode the backlight would turnoff on the screen and would never come back on. at times after a numerous amount of button pushing it would come on and sometimes if i continuously slide it up and down it would come on. I thought it would be a software problem so i installed the rhodium ram on it and the problem still occurs. What can i do to fix this and why is this happening?
