SN75DP130: ESD test will cause black screen.

Part Number: SN75DP130

Hi Team

Customer test ESD performance in there product. they use SN75DP130 to drive the screen.

They would like to resolve the ESD black screen problem.

When they read the I2C register form SN75DP130 , They find 0x18 and 0x1A will be changed when black screen appear.

so do we known what the mean of 0x18 and 0x1A which is TI Test register?

Do change of 0x18 and 0x1A will cause the black screen?

Do we have any test method to help us find the root cause?

Thank you very much.
