yesterday i fixed a no video ps4 which was sit on my “for parts” shelf… (i have a lot of free time staying at home) yesterady started replacing diodes, resoldered ic, replace hdmi port (i was just shooting to the sky)… i was absolutly sure ic chip was damaged but i had no spare ic’s now, so my last measure was continuity between ic chip and hdmi port pins… and guess what? there was one point with no continuity… so i replace that coil and voila… and actually i checked everything and i was sure those coils were fine…!! mi teaching is… triple check everything…!! sometimes points usually got bridged and it’s hard to notice…! or there is a chance that ic is not good…!
