It might be getting disabled. it is a setting of adv7343. just look into the driver and see where it is getting disabled.

I'm sure ADV7343 is enabled, the output of the ADV7343 has the following waveform output.

Hi,

I think you were asking about why color bar is getting stopped. there is a configuration in adv7343 to enable/disable internal color bar. But disabling color bar does not stop the output, it will still output untill output is really stopped.
