PS4 won't turn on after repair

I recently did a full tear-down on my PS4 and it won’t turn on. When I took it apart it was completely filled with “Crunchy” dust so I used Q-tips and isopropyl alcohol and cleaned all that could be reached. I followed a step by step guide and put it all back together without any missing pieces. I waited an extra 24 hours just to be safe and let it dry/evaporate. I’ve tried just about anything and am down for any ideas. I think it’s a PS4 Original but am unsure.
