Monitor problem. How to fix?

Question

Monitors

Good evening. When you start the PC, you can see information about the motherboard, the windows itself starts, but a second later, after I already see the desktop, the monitor just goes out, while the power light on the monitor is on.
If you disconnect and reconnect the monitor's power cable, or as I found out, you can simply press the on / off button on the monitor (as I do), then it starts for a second or two, and then goes out again (if you restart the PC, the problem is solved with first time). I turn the monitor on and off until it shows the image constantly, when it has already turned on and does not turn off, for a second such a quiet sound (beep) is heard, as if the power had been applied somehow. My friend and I sin on the nVidia video card drivers, because. it happens to him occasionally, but after the first reconnection of the cable, the monitor works and works fine. By the way, even after a 15-minute "non-touch" to the PC, the monitor goes out (I know that this is normal - this is a Windows setting that changes in the control panel and power supply), and do not touch it for a long time, then the same annoyance occurs. It happened somehow suddenly, I hope for help, it's just tired of wasting time on this every time.

Answer 1

The capacitors are dead, the backlight goes out, the image should be present. Shine a bright flashlight on the screen and make sure there is a picture.
Solder all swollen conders

Answer 2

It looks like the monitor goes into protection. And what is there, the power supply, the backlight or something else, you need to understand additionally.
Squeak - there may be chokes, and there may be capacitors that like to "swell". Or maybe it's all the backlight lamp whistles.
