820 3115B.... NO Image on LCD

when I plug the power supply, it chimes and there is a light on the screen , but no logo or anything.

I'd appreciate your help
 
I can see a little carbon on both pins of LCD where LVDS_CONN_A_CLK_F_N / LVDS_CONN_A_CLK_F_P connected

Voltage on L9080 : 1.21 on Pin 1 and 1.24 on Pin 2

is there any way to clean the LCD connector?

I was expecting you to check L9080 continuity.

Resolder LCD connector, or change it (if really needed).
