2013 iMac Won’t Start Up

[Papanate]

I was given a 2013 iMac 21” - it started up 3 years ago no problem - it sat in a loft for 3 years neglected and alone - now it won’t even start - no fan noise - no black screen etc…before I take it apart to check the LEDs - is there any thing I can do? I’ve already tried the unplug it and pressing the power button for 20 seconds then plugging it in and pressing the power button for 20 seconds - nothing.

Ideas?

Try another power socket?

If the power socket switch doesn't help, sounds like it might be the internal power supply.

For a 12-year-old iMac, probably not worth the cost of trying to repair it, unless you can get the parts REALLY cheap and then do the work yourself...
