How to restore the monitor (reset bios)?

Question

Do it yourself

Monitor LG Flatron L1950SQ.
It suddenly turned off, and after a few hits on a tambourine, connected only to the mains, it began to do the following:
- Turning on the power button / indicator
- Monitor screen saver (Flatron) for a split second
- Shutdown and start all over again
What could be the matter and how to fix it?

Answer 1

Judging by the symptoms, the power supply goes into protection, one of the backlight lamps may have burned out.
The lamp is either changed or "emulated" (replaced with a suitable high-voltage capacitor for example).
Can also be replaced with LED lights.
But if the question arose "what's wrong with him", then it's better to go to the service.
There is also a possibility that the firmware has flown, then replacing the memory and uploading the firmware.
