When 947 and 948 are powered on, there is a small chance that the screen will display abnormally. When measured the lvds, the lvds signal input to 947 is fine, but the lvds signal output by 948 is abnormal.

the  register dump of 947,948，Is there any problem with the register?

    Hi,

    Can you check if the 948 lock is high? Could you clarify the abnormal display issue? Is it showing a black screen, or is the PATGEN on the 947 working normally but not on the 948? Also, could you send me the register dump in a readable format so I can copy it or load it into ALP.

    Best,

    Josh
