iMac LED 1 & 2 are on, chimes but no display
I have a 27” iMac mid 2011 and suddenly the display went blank.
I checked the onboard diagnostics and LED 3 and 4 are off.
I purchased a new graphics card and logic board but now the same problem. LED 1 and 2 turn are on and LED 3 and 4 are off. What is the solution ?

Check your cables, its also possible you got a bad logic board/GPU
