The customer is using TFP401A to connect the display screen, and there is a flashing screen phenomenon when starting up. It is speculated to be a timing issue, and the backlight should be turned on first. Please help analyze the cause. The display screen is shown in the following figure.

Hi,

Can you please share your schematic in .pdf format? What is the targeted resolution? The TFP401 can support video without audio only, is the audio being turned off in this particular case?

Thanks

David
