sorry this is an iMac question, do you repair iMacs btw?

After much micro-soldering practice, i finally went for it and purchased an iMac at a deep discount that would require replacement of the 60-pin DisplayPort connector, and hopefully flip it for a profit. I tried it twice, and each time the screen wouldn't even power on, and only the first two LED's lit up. Granted, i'm not very elegant or efficient with micro-soldering yet, but i don't know anything i did wrong. Didn't see any joined pins, as far as i know no solder got into the connector from the side connections. Maybe the ground pins didn't completely connect to the board? (they can't really be wiggled to test out like the other pins can) Can you possibly give me some tips, pitfalls to avoid, common critical errors, etc. I figure this issue can come up with MacBooks as well, so hopefully you can offer some advice. thank you!

First of all, welcome to the forum!

You should test first if the machine turns on without LCD connected.
See if all voltages come on and get USB activity and external video.

What is the 820-xxxx code of your board?
