iMac A1312 BLACK SCREEN
I have an iMac A1312 27"
It was working properly but NOW it turns on make the Apple CHIME. but SCREEN is totally DEAD (NO VIDEO).
At first I tought it was the POWER SUPPLY for the LCD. I changed it with a brand new ONE. NOTHING HAPPENED.
Then I started to think that it is related to the connector on the logic board and I am thinking right now to REFLOW it. What do you guys thinks?
I heard that it may be the GRAPHIC card. BUT when I use the THUNDERBOLT to an external display it works fine.
The computers works 100% fine but dont GIVE image to its own LCD.
Sometimes I think there is no energy going through the LCD cause if the CONNECTION from the LCD to the logic board is not good it stills could produce some energy like a MONITOR without anything plugged at it. DOESNT it?
Es esta una buena pregunta?
