Il Mio Problema
The HDMI port on the PS4 I bought when they first came out took a crap on me and stopped working entirely.
La Mia Riparazione
Ordered a new motherboard and paired optical drive from ifixit.com. Took approximately 45 mins to replace both. Very helpful step by step instructions on the website.
Il Mio Consiglio
ifixit is legit.
