Hello
I received 27" iMac, Late 2015 model that's broken. I don't know what exactly happened but it appears to be unopened and there are no marks indicating prior repair attempts.
Initially it didn't display anything on the screen and backlight didn't work. Only 2 diagnostic LEDs would light up and 3rd was very faint. I opened it and found F4400 fuse near eDP connector to be blown. Replaced it with a suitable part and backlight came back to life. Unfortunately it still doesn't display anything on the screen. Now I get 4 green diagnostic LEDs.
I can hear the chime... -

I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
Programmer models: XGecu TL866II Plus / T48 / T56 / T76

There's also an extra OTP Secu.R... -
With original bios in attached, the imac starts but only 2 status led.
can someone help me?...
