No backlight after adding SSD drive
Hi to everyone!
This is my first time here posting a question, although i have always been a regular user of iFixit, helping me with a lot of issues. However, I'm having a strange problem and cannot find a specific answer for it.
As a start, sorry for my english not being it my first language. I have disassembled today my iMac to add an Apple SSD Drive 128Gb so I would enable Fusion Drive (having a 1TB HDD 7200rpm). Everything went smooth, but when I put everything together, there was no image on the screen. Having disassembled notebooks, computers for about 12 years, tried the usual troubleshooting and came to the conclusion, with a torch in my hand, that the LCD was working, the iMac booted fine, but there was no backlight. So i took out again the LCD, tested the cables on the back of the LCD thinking i had torn any of them. Tested the display cable, the power cable of the lcd, everything ok. I then thought it was maybe a problem with the light sensor, or maybe the light was dimmed at it's lowest value, nothing. Reopened the iMac, removed the SSD drive, still the same. Has this thing happened to anyone of you? I can't seem to find nothing about the new iMacs, only about the older ones.
Hoping for an answer.
Ist dies eine gute Frage?

Well, 6 months later, after buying a new LCD and a new logic board, i have the same problem. Now i have two logic boards, two displays and a non working iMac. Has anyone found any solution to this problem?

Does anyone have any idea on the solution for this problems. Its strange that even after changing the logic board where the led driver is , i still have the same problem. Is it possible that the ssd that i installed could be the problem? How can it damage the LED driver
