I wanna ask you about my imac A1419. It doesn’t have a display and I connected it with another screen but it looked all white. What should I do to make it right and get it work with the screen
Man you didn’t show us the jumper that you put on what did you solder it to jump the fuse? Like solder one side of fuse to the other side of the fuse? Or one side to a different component ? I was waiting for you to do a close up of the board after uou finished soldering it but never showed us you just put the screen back on
Hello, my imac late 2015 retina has pink edges all around - 1 cm distance from the black border of the screen. Any experience on this or recommendations if this is fixable. ? Thanks in advance.
If you force the ribbon cable and hurt one of the pins on the connector on the board and the pins short together do you think that it would blow that fuse or you might have a chance that it did not blow the fuse?
I got an A1419 iMac with the same issue. I connected the fuse F440 (1-> PP12V_S0 2-> PP12V_LCD_F) with one wire (to close it )and the display turned on like in the video. What is the permanent solution?
I also went to take the front off and it fell. I get all 4 diagnostic lights but no display. I got a new LCD ribbon but it must be the connection where the ribbon inserts or a bad filter like the one Rosmarky just replaced.
Thank you so much, guy. You saved me hours of search to find that fuse location, I wasn't able to find out the PCB layout to be able to locate the F4400; do you know where download from?
@@RosmarkyTechnicalSolutions He's referring to the diagnostics LEDs. (There are 4 of them on the main logic board) A single lit LED means that the device is plugged in to power. Press the power button and the second LED will light. The third and fourth LEDs are the status of the GPU and the Display.
@@RosmarkyTechnicalSolutions Power Cord : Make sure the power cord is nice and tight on the backside. I just went thru this. I thought it was the Power Supply and it was not. I would get the first light then push the power button and the light would go off. Thought maybe it was the power button, but NO. All along it was a loose-fitting Power cord. I tried different window power cords and they all felt like a good tight fit but NOPE it was the power cord all along.
