put a lcd on 21.5 iMac a1311 can here it boot but screen is black
Bought a used iMac A1311 without a display screen. It was tested before I bought it and was released by an apple tech as it functions as intended.
Bought a screen and installed it. Turned it on and got 3 beeps. Checked and fixed the RAM and tried again. This time got the Apple chime could here it booting but screen was black. Also replaced cable #593-1280 A. Double checked everything still a black screen.
Haven’t tried an external display yet, had to order a Mini DisplayPort adapter.
In the meantime any ideas what I can try while I’m waiting for this adapter.
Any help will be appreciated. Thank you

Bought this iMac used from a reputable seller of macs. He tests everything he sells. All it needed was the screen which I bought separately, also replaced the main cable 593-1280A.
I did have trouble plugging it into the logic board, tight squeeze! But the vertical sync cable won’t connect where it’s supposed to go. One Mac has a plug in cable and the other has a ribbon connection. The ribbon looks damaged could this be it?
