LCD flickering BB revC5

Hi all
i’m working with a BeagleBoard rev C5 with LCD from Liquidware, but the display has flickering and the color goes near red.
I think that the problem is the frequency,but i can’t find the correct value.
my bootargs are:
setenv bootargs ‘console=ttyO2,115200n8 noinitrd omapfb.vram=0:8M,1:4M omapfb.mode=lcd:480x272MR-16@60 root=/dev/mmcblk0p2 rw rootwait rootfstype=ext3’


setenv bootargs ‘console=ttyO2,115200n8 console=tty0 root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait’ ‘omapfb.mode=lcd:480x272-16@65’


setenv bootargs ‘console=ttyO2,115200n8 console=tty0 root=/dev/mmcblk0p2 ro rootwait omapdss.def_disp=lcd omapfb.mode=lcd:480x272’


setenv bootargs ‘console=ttyS0,115200n8=noinitrd ip=dhcp rw root=/dev/mmcblk0p2 omapfb.mode=lcd:480x270MR-16@60’

for each args i have the same response.
i’ve seen that when i take the terminal (ctrl+alt+F1) i don’t see the flickering effect!!
There is someone who can suggest the correct boot args?
Thousand thaks, for all advice!!
