When it goes amber, that means it is not detecting the video signal form the PC, the on screen menu function will not be working either. So check your cable, it can be due to bad logic board.
No bad caps that you can see?

It can be circuits or failed component on the inverter/power supply board or bad lamp assemblies.

It only takes one bad lamp to cause the circuit to go into shutdown.

Just had one of these monitors, completely dead. Cause: the "down" button was defective, was always active. The MCU is then blocked and the monitor can't be turned on.

Fortunately schematics are available, saved me a lot of time:
