Philips Monitor 230E1HSB/27 - Screen goes black seconds after working

I started with trying this monitor on a chromebook. The screen went black seconds after working. Note the monitor power led stays lit. I tried a different HDMI cable which works on other devices. I have replaced the power inverter board - 492191400100R ILPI-136 which did not fix my problem.

Philips Power Inverter Board - 492191400100R ILPI-136. Inverter interface on the left side of this board. Since the screen works in the first few seconds the inverter is working.

Philips Interface Board: What could causing the black screen? Is it possible the interface board is not working as it should? I have yet to try replacing the power cable but I have my doubts.

Please any suggestions would be appreciated.

You didn’t say whether you tried the monitor on a different device.

Did you go into settings and select ‘mirror display’ on the chrome book?

The screen went black seconds after working
My external monitor too goes black after a few seconds without signal (although it says so on the screen before it does). Make sure the computer issues a valid signal on the HDMI port. Or try another port (DP, DVI, VGA, whatever is available on both computer and monitor).

I tried a different HDMI cable
Make sure the input is set to HDMI in the monitor settings.
Try the monitor on another computer?

Your doubts are justified: If the power LED stays on, there is power to the monitor and the cable is the most unlikely culprit of all.
