Hello all
RE; iMac late 2013 , 2.7Ghz, 21.5” A1418 , 2638
Having dismantled the main screen (as per ifixit tutorial) to get to the hard drive and then reassembled.
Reset the SMC (power off, unplugged at wall, hold down power button 30 secs)
Reset the PRAM (machine chimes, and resets and chimes ok)
-
When machine powered on,the Green Light on the logic board is lit. And the main screen doesn’t light up…….
+
Noticed there are four green LEDs on the logic board. one lights when plugged in. The other two light when powered on. however the fourth LED doesnt light up…
The internal display cable is seated properly at both ends. All other cables correctly seated too.
The machine worked great until had to remove and change internal HDD.
Any ideas what it may be ?
Unable to connect to an external monitor to check if display shows.
I have a 2011 MacBook Pro 17’ with thunderbolt port , is there is anyway I could connect the iMac to the MacBook Pro to check display?
