Problem with lcd display after booting imx53qsb from sd card

I have installed U-boot, the linux kernel and root file system on my sd card from which I intend to boot my imx53qsb. It boots well, but after the boot process I don't get a proper image on the lcd display. Instead, vertical multicolored lines appear on the display and the terminal window on my PC gets filled with random letters. Here are the parameters that I set before the boot process:

 

 

MX53-LOCO U-Boot > setenv bootargs_base 'setenv bootargs console=ttymxc0,115200'

MX53-LOCO U-Boot> setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/sdb1 rootwait rw video=mxcdi1fb:BGR24, XGA di1_primary tve'

MX53-LOCO U-Boot> setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc read 0 ${loadaddr} 0x800 0x1800;bootm'

MX53-LOCO U-Boot> setenv bootcmd 'run bootcmd_mmc'

MX53-LOCO U-Boot> saveenv

MX53-LOCO U-Boot> run bootcmd

 

Does anyone have any idea how I can fix it? Your help will be appreciated.
