Hello;
My first post here, so don't blame me too much if i'm not following some guidelines I didn't knew before.
The context: bought about 3 weeks ago a second hand dead ps4 to repair, witch was seriously butchered by a "repair shop" on the hdmi port.
After removing it, and micro soldering maybe 7 wires directly on the new hdmi port to restore the motherboard connection to various places, the ps4 is now booting, showing a nice hdmi image. Still got a couple of things to repair on the motherboard (is this a buzzer that is not far from the hdmi? and the optical connector that has also been damaged by heat). Anyway, it looks like it works. So I started my search for cheap dead controllers to repair.
The first one was working, so won't talk about it (it's only cosmetic damage, parts from china are one the way).
The second one wasn't powering, not charging, draining 0.0A from the regulated DCPSU.
After teardown, and quick analysis, nothing to see. Many people say "yeah it's the micro usb", so I purchased a couple (on the way also from china), but looked deeper on the board.
I had a short, not far from the 7736FTG chip (probably one of it's power cap, it showed me unusual look on the microscope, so decided to replace it, as it looked damaged on one of its legs). Removed the cap, and "voila" the board is now charging the battery, the light is on, sucking around 0.2A from the usb wich sounds pretty good to me.
Before spending another hour to rebuild this controller I would love to replace that cap, but wtf ? that's sony: no schematics around arrrrrrg..
I'm guessing I shall put something like 1-10uF 6.3V there, what's your opinion?
here is my capacitor missing, any help will be appreciated, and thanks for your advices.
PS: I tried to find a way to resize (reduce size because it's a bit "big" on the board, but willing to leave a high def source), but couldn't find any way to resize (I'm hosting the image source don't worry for the storage space ;-) ).
If you are interrested in my previous job on the PS4 for the HDMI rescue, I can make and post pictures, the beast is not reassembled yet, the DVD cable were salvaged by previous "repair" shop.
