Hello,

I believe the power led button is still on while the screen goes black, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes black after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes black.

The best thing for you to do now is to take the monitor to a local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself in other to complicate issues.

Take care.

Normally when this type of problem happens, the first suspect would be the inverter board, then the filter capacitors and lastly the mainboard.
A defect in one of the lamps and faulty inverter IC may cause the display to shutdown as well. If the lamp is defective, it will send a feedback and cause it to stop producing output signal thus the display just shut off once you switch in ON.
