    Have you tried other good lcd panel?

    Most of lcd panel have an input for test.

    Google for "LCD Panel Self Test Enable".

    Probably panel is in test mode.

    i have several 3115 boards and the panel works fine with the others boards. i've changed the lvds connector and tested continuity with pin 17 & 18 and the test points for lvds_ig_a_clk_n and lvds_ig_a_clk_p but i still get 0v on pins 17 and 18 after the board chimes
