Part Number: TDA3XEVM

Tool/software: TI-RTOS

I design a board based on TDA3x, The Analog video is used. But the PAL vedio is not right which had half dotted line as follow. The N vedio is ok

We used the default configure as TDA3xEVM

What happened

This seems to be some blanking data. Does it come even when you are not displaying anything? I mean just after starting the display..

Hi,

Can you try moving start of line by one line and check if the artifacts goes way?

Do you mean change the register VENC_HS_INT_START_STOP_X

Hi,

Not the HSYNC start, you will have to play with the VENC_FLEN_FAL register, this register decides start of the active video.
