The specification table lists DC 12V / 1A. Depending on your setup, power may come through the supported connection method shown in the manual, but the monitor should always receive stable compatible power before troubleshooting image issues.

For common setups:

Troubleshooting KTC H15F9 Portable Monitor Problems
Why is my portable monitor screen blank and the power light is off?
The manual says to check whether the monitor is connected to power correctly and whether the contact is normal.

Adjust brightness and contrast in the display menu. A dim screen does not always mean the panel is damaged.

Why are there dark spots or bright spots right after powering on?
The manual says this can be normal when the display is first powered on and that it should become stable after about 20 minutes.
Why does the picture look distorted, shaky, or like it is flashing?
Check whether the source device is set to the correct configuration, resolution, and refresh rate. The manual specifically suggests checking those items.
Why do I hear electrical noise after powering off the monitor?
The troubleshooting note says this can be caused by the monitor releasing the remaining electrical signal and is considered normal.
