When a Cinemonitor HD6 Classic shows no image but has power and backlight, verify that the input signal is present by testing with multiple cameras and trying different refresh rate settings like 30Hz, 60Hz, or Auto.
A factory reset can be performed by pressing and holding the Adjust button while powering on the monitor.
If the monitor displays no sync with an HD-SDI input from multiple cameras, testing with an analog signal via an 8-pin Lemo connector using a downconverter can help isolate whether the issue is specific to the HD-SDI input or affects the entire monitor.
Power cycling the monitor by switching it off and on may restore signal reception when the camera battery is switched.
If troubleshooting steps including factory reset, input verification, and signal testing do not resolve the no-image issue, the monitor may require service from the manufacturer.

The user's specific issue was not fully resolved through the troubleshooting steps documented in this thread.
Testing was limited to RED Epic and RED Scarlet cameras and one other 8-inch monitor.
The final resolution and service cost from the manufacturer were not reported in this thread.
No information about whether the HD-SDI input issue was ultimately hardware failure or a correctable fault.
