iMac 27 mid 2010. Screen randomly turns off/on after OS's boot. I tried to replace the inverter board and the power supply from fine working iMacs, tried to connect it to working Macbook as external monitor, formated HDD and reinstalled with different versions macOS's, also tried the lcd display cables they seem to be fine. So the problem remains. Any ideas? Thank you!

When you are swapping parts out are you resetting the PRAM? Often you'll need to do this or the Mac will not accept new parts.

Also did this dozen times and nothing changed, could it be something wrong with LCD display? This iMac had lightning thunderbolt damage and had already been replaced with power supply board and worked with it about half a year

Did this after replacement of each parts - power supply and led investor boards, and this did not help. With another invertor board screen turned off even faster after apple's boot logo disappearing.
