How to reset the screen through command?

Yes, problem is WSOD (white screen of death). Sorry for my poor english.
But the problem still here using the last kernel.

The version of my OS are (got from
http://build.shr-project.org/shr-unstable/images/om-gta02/) :
uImage-2.6.34-r7-oe16-om-gta02.bin	17-Jan-2011 17:26
full-om-gta02.jffs2	04-Feb-2011 12:46
