Dear All,

 

     Issue : Hum bars present on my monochrome monitor (Horizontal bar present on display) which is going from bottom to top.

 

                I am generating differential composite video(Monochrome video) which has been convert to single ended video signal and given to mono chrome display. But when video is observed on screen ,I observed the horizontal bars on screen.and my issue is how to remove these horizontal bars(know as 'Hum bars').

 

Note : I have shorted chassis of my module with zero ohm(0 ohm) resistor to GND of the same module. Is it one of the cause for hum bars generation.???

 

Regards,

Tendulkar S
