hello,
I have a ps3 slim model CECH-3004A which has image on AV port but not on hdmi port, I changed twice the hdmi ic chip with no success. I tried to check some components on the motherboard and I have seen that the chip n°1 on the picture which is Mitsumi MM3348 has it pin 2 which should provide 5v to pin 18 of the hdmi port through the component n°2 is connected to ground. (I got the information concerning Mitsumi MM3348 here https://www.psdevwiki.com/ps3/MN8647091
the arrows show the pins connected to ground while they should not.
I think there is a short somewhere.

I also want to know what is the value of the smd diode on the second picture.

I need your help.
Thanks

I know little about that but did you tried to reset the PS3 display settings holding the power button and then removing the finger after hearing a single bip?
