No display and no chime.

2017 iMac with display issues and no chime at boot.

1st 3 LED’s light up but the 4th LED will not light up and external display does not work either.

If the cables for the monitor are attached fan moves slowly. If I disconnect the cables and turn it on fan blows at full speed.

Is this a display issue or a logic board issue?
