The backlight of LCD is bright, but no image .thanks !!

Hello Johnny,
Could you please provide more details about your environment, such as the platform and the display configuration used, the software release, and what steps you are taking to reproduce this problem. This forum guidelines provides details on what type of information is needed in a post to ensure a speedy answer.
Also, it would be appreciated if you would attach logs to the post in a separate file, instead of embedding it in the description of the post - it would make it much easier to follow!
Regards,
Magdalena

Hello Magdalena,
Thanks to reply , I worked on omap4460blaze tablet using the kernel 3.0.8, and i used the chimei lcd to display. I registered on platform as showed:
struct omap_dss_device omap4_lcd_device = { .type = OMAP_DISPLAY_TYPE_DPI, .name = "lcd", .driver_name = "chimei_lcd_panel", .data = &omap4_lcd_panel, .phy.dpi.data_lines = 24, //.reset_gpio = PANDA_DVI_TFP410_POWER_DOWN_GPIO, .channel = OMAP_DSS_CHANNEL_LCD2,
/*dpi set dsi clk */.clocks = { .dispc = { .channel = { .lck_div = 1,// Logic Clock = 200.05 MHz .pck_div = 2,// Pixel Clock = 100.02 MHz .lcd_clk_src = OMAP_DSS_CLK_SRC_DSI_PLL_HSDIV_DISPC, }, .dispc_fclk_src = OMAP_DSS_CLK_SRC_DSI_PLL_HSDIV_DISPC, }, .dsi = { .regn = 27,// Fint = 1.4 MHz .regm = 422,// DDR Clock = 120.03 MHz .regm_dispc = 6,// PLL1_CLK1 = 200.05 MHz .regm_dsi = 6,// PLL1_CLK1 = 200.05 MHz .lp_clk_div = 5, .offset_ddr_clk = 0, .dsi_fclk_src = OMAP_DSS_CLK_SRC_DSI_PLL_HSDIV_DSI, }, }, .panel={ .config=OMAP_DSS_LCD_TFT, }, //.state=OMAP_DSS_DISPLAY_ACTIVE,};
and the lcd display configuration is :
{ .x_res = 1024, .y_res = 768, .pixel_clock = 103000,//96960, .hfp = 260, .hsw = 256,//tpe is 320 but the range 0-256 .hbp = 480, .vfp = 16, .vsw = 10, .vbp = 6, },*/ // .acbi = 0x0, // .acb = 0x0, .config = OMAP_DSS_LCD_TFT, //.power_on_delay = 60, // .power_off_delay = 30, .name = "chimei_lcd", },
Johnny,
This seems to be a duplicate thread of http://e2e.ti.com/support/omap/f/849/t/182300.aspx. Please confirm.
Thank you,
