Various issues could cause this. If you are a tech. Or know one
1 If the ring around the power plug is lit:
- Check MOSFETs on the front end. Both sides - Usually AO4407 or AO4422 to the bottom surface (which faces up when opened), and FDS6679 on top surface, just below the square power plug from DC Jack.
- Check the black ribbon cable connecting the power board to the motherboard. (the left cable is for power) It could be unseated, or fine connectors broken, or ribbon has break in leads.
- Check to see if you can turn it on with remote control if your model has one.
2: if the ring is not lit,
- check your AC Adapter
- check the wall plug (mains in UK)
