Hello. The monitor failed again. The computer was in standby mode, I pressed the key to exit it, but the monitor did not turn on. I rebooted the PC - the monitor stupidly does not show the image. I took out the BIOS battery - it's all the same.
When the computer is turned on, the monitor does not show anything, but the display lights up a little, and then after 2 seconds it goes out again. And so every 5 seconds. Even when the PC is off, the indicator lights up blue, then a click and the indicator just goes out. Also every 5 seconds.
What should I do? Help me please.

Backlights (but this is not accurate)

Borrow a monitor from friends to check whether it is a PC or a monitor. It is possible that the capacitors in the power board have dried up if the monitor is > 5 years old. Do-it-yourself repair + 100-150r for high-quality capacitors such as Jamicon WL. Or take it to friends who are friends with a soldering iron.

Have you considered the option of a dead monitor? I had this - there was a monitor, it worked, it worked, and once it refused to turn on. The monitor was old, I took it ... to the trash :)

Had almost the same problem. It's most likely related to the monitor. As advised above, just connect another working monitor, if it has the same problem, look for problems in the PC components, if the problem has disappeared, change to a new monitor. The probability is small, of course, that the reason is because of him, but still check the connection cable.
