LCD turning white after a few minutes

Hi all-


I have some strange behavior on my board and LCD

It's a custom iMX6S board running Linux 3.0.35. The display is a parallel LCD (8-bit) using BT656 protocol.


After booting, I display an image on the LCD. After a few minutes the display suddenly becomes white. At that point, if I try to display a new image nothing happens.

However, if I do "echo 0 > /sys/devices/platform/mxc_sdc_fb.0/graphics/fb0/blank", then I can display images again. But, again, after a few minutes the LCD turns white.


Any ideas what might be causing the LCD to 'turn white' by itself?
