iMac not booting after thermal paste replacement

crwdns2934249:0crwdne2934249:0:

I just replaced the thermal paste on my iMac, and now only one diagnostic LED is lighting up, witch means that it’s getting AC voltage… I know it’s not the power button because I heard the little click from the PSU when I pressed it.

Here’s a picture if this could help:

=== Update (03/04/2023) ===

Okay I just extracted the CPU from the iMac to make sure that none of the pins in the socket were bent, and I noticed that the CPU itself got bent. I have done a lot of thermal paste/ CPU replacements and never seen this. I think it happed because I took the hsk off and the cpu came with it, and it got crushed. Could I use an i7-3770 or do I need a 3770s
