How I can repair Samsung LED Monitor Series 5 / 570
If the display has no signal ( no cable connection with a device ) I can see an easy jitter of the signal search sign on the screen. After the hdmi cable is connected with the device, the jitter disappears and the screen is staying dark :-(
Is this a good question?

@samson50 sounds like a main board issue. What is the complete model number for your monitor and what have you checked?
