Dear everyone

I have a problem on backlight screen (black screen) but after 30 minutes the backlight going to be working. That's so weird. When I restart the iMac, the backlight has working but if I shutdown and restart, the backlight has been no working again. I open my iMac, and nothing looks burning or other problems. I make all your test like on YouTube topics. So, my question is: did you have any idea what's wrong?

All 4th led on motherboard are lighting.

Any components are burning on motherboard.

I get this issue after ssd and ram exchange. But at the begening it was working. the issue appears after few days.

Thanks for your feedback and help everybody

Sorry for my english, I'm Italian 🙂
