iMac possibly broken - someone who know what to do with it?

#1

Hi,
over the last few weeks I’ve found the screen of the iMac shadowed on the left. Thought it might be some funky setting but according to @Elizabeth99 it’s broken. Everything still visible, colours are dimmed tho.
The iMac is a fun thing to have. Is there anyone who can have a look and see what can be done?

It’s a faulty backlight by the sounds of it, depending on the model it’s likely an older model so it could be faulty capacitors on the inverter or a failing tube. If it’s a newer model it’s some dead LEDs or power supply.

Apple products have a marketing number Axxxx which you can find on the underside of the foot of the computer, if you can get this we can find a takeapart guide and then we just need a willing volunteer to try and fix it.
