It's definitely significant for us, thank to so many
You're welcome, we are happy the video helped.
in my case, the replacement of four 35V 220uF capacitors helped, previously I checked the voltage on the DC BUS and it was ok also the voltage of 24V DC between terminals 12 and 20 was fine

I have an old vlt 2800 which the display will come on after a long time when energized but today the display stayed out, what I did: put the power out and took the wire out on connector 18 and 20 and then I put the power on. Direct the display started up 🤗
Lucky me.

Blank display, I think that problem is in firmware of LCP or interrupt data stream.
