iMac chimes but display won't power?
I have opened and closed my iMac (first time at repairing an iMac) and thoroughly check that all my cables are plugged back in, but even though the computer powers on and chimes (and all 3 LEDs are on), the display does not seem to be powering on at all.
I don't know what else to say, it worked fine before I opened and now it doesn't. I'm at a loss!
Long story (maybe some clues?)
When my mid 2010 i3 21.5" iMac's internal HD's smart status said it was failing I decided it would be a good opportunity to upgrade the storage and fix its broken supper drive.
Everything was supper simple (asides from the connectors being very stiff first time through) except for the display data cable, which popped off before I could see how it was attached originally.
I loaded in my new parts and proceed to close the machine back up. But the display cable gave to a world of trouble, I think mostly due to the cast I didn't/don't know which way it goes in. The flip down lock thing doesn't work very well and my cable had a kink in to that make the "plug bit" pop out very easily (the way it is kinked also made my confused about which way it was supped to plug in). I think I was trying to put it in backwards to start and after reading a bit more on line I am probably lucky I didn't brake the connector on the motherboard with all my pushing.
After trouble shooting for several days and popping and closing the machine 100 times I think I have the back of how to get Citi to stay now.
When I went to power the machine on, I heard the chime, and the computer working for a few moments and then nothing. The display did nothing. No indication that it is even on.
Long story short I put all the original parts back in and the display still doesn't do anything.
- I have checked the internal LED diagnostic lights and 3 of them are on when I power up the computer.
- I don't have a mini display adapter to try a secondary monitor at the moment.
- To the best of my knowledge the display data cable looks fine. But I can't find any good pictures online or information about what it is posed to look like or how it works. So I have uploaded some photos of mine. Doe these all look right?

Upon Closer inspection it looks to me like the plug on the data cable has been chipped and must be damaged.
Update # 2
I have tested the iMac with an external (only had a cathray tube monitor tube laying around to test with, Yuk!) and the new SSD is working great.
I got my new display cable in, it fits perfectly but to my dismay the display is still not powering on and the 4th LED is still not on! Any ideas what is going on? (Also checked the display settings and only the external display is being recognized by the computer)
So in way we're back to square one. The computer works, but the internal display does not... What should I try next?!?!?
