Observations:

• He took it apart with a disc in the drive
• When powered up, it would not eject the disc, so we had to manually eject the disc
• When he removed the ribbon cables, he just pulled them out (didn't release the latch on the large drive ribbon cable)
• When I took the drive apart (he did not take the drive apart previously) I noticed it appears to be missing a white plastic piece from the top metal plate next to the manual eject screw based on comparing it with pictures online
  • If I put a disc in until I meet resistance then use the manual eject to pull it in, it pulls in fine and everything appears to be functioning, so maybe we're not missing that piece. No idea how it could be missing since we'd never had it apart before.
• When I press eject with no disc in, it beeps 3 times which I read means there is no disc, so it appears to know it's empty.
• When I try to insert a disc with the console off, it turns on, so it recognizes me trying to put in a disc.

What I've checked:

• Both fuses F6201 and F6202 on the motherboard have continuity with .2 ohms resistance max.
• All three ribbon cables have continuity from the motherboard pins to the daughter board pins, so ribbon cables appear to be fine.
• All the micro switches (3 that I can find) inside the drive are open when the pin is extended and closed when pushed in/arms are open to accept a disc.

I have already tried:

1. Unplugging the console for over 20 minutes to perform a power cycle.

2. Attempting a "Disc Wake-up" by inserting a game disc (the drive does not take the disc).

3. Attempting to boot into Safe Mode by holding the power button (no response).

Given that it crashed multiple times before failing, is this likely a Power Supply Unit (PSU) failure, or could it be a more serious motherboard issue? Are there specific components or fuses I should test with a multimeter?

• Left my PS4 Pro unplugged for about 2 months while I went back to my hometown
• When I plugged it back in, the console does absolutely nothing (no blue light, no beep)
• Normally it shows the blue light after a second, but now there’s no light at all
• If I put my ear near the PSU area, I can hear a very small click or faint electrical noise
• When plugging in the power cable, I can hear a small sound from the plug/PSU
• I already completely disassembled it and cleaned both the PSU and motherboard, only handheld turbo fan (low to medium dust blowing mode, not high pressure)
• No visible damage, no burnt marks, no bugs, nothing looks wrong
• I tried drying it with a fan before because the weather here is quite humid, just for sure
• The console still does nothing when pressing the power button,enject or use controller to turn on(no connection)
  
  -The console was working fine the last time I used it. I left it unplugged before going back to my hometown. Previously, the PSU had a coil whine issue but it still worked normally. The disc drive also made a loud noise on the first read, but it remained functional. I didn’t bring a multimeter with me when I returned because I didn’t expect this problem to happen. I also haven’t tried another PSU yet, but I plan to test one in the next few days. For now, I just want to understand what might have happened.

A couple of months ago, I tried to disassemble my PS4 pro and it didn't end well. Long story short, my PSU was a bit bent and I broke traces on the edges. I soldered it, but it didn't work - when I pressed "turn on" button, a blue light was emitted for a second and instantly turned off. Furthermore, PSU connector was torn off, so I had to solder it too. Recently, I bought a new PSU thinking it would make my console work. But no, nothing changed. Except, now it makes 4 short beeps after the second attempt to turn it on (I marked a place where the sound comes from). I'm clueless; it SHOULD work. Any advice will be greatly appreciated!⏎

Recently the PSU on my ps4 pro blew (popped cap) so I got a new one, the previous PS4 pro had the ADP-300P1A PSU in and my new one has the ADP-300CR.

The new console was being very loud so i decided to swap the PSUs around but it appears that the small connector cable for each is different so I can’t swap them between consoles, does anyone have experience of this?

Thanks!

Does anyone know what component this is marked in the image and its value? I saw in another image I found online that it appears to be a resistor.

If anyone has a board they can measure and tell me, I'd be very grateful!

the behaviour is as follows,

when I switch on power from wall socket and try turn it on form the 1st time it gave me 3 beeps and turned off, when i tried to tun it on it gave a beep and went into safe mode. which ever option i try in safe mode it boots back to safe mode(loop). Tried update with pendrive and also full reinstall as well.
i read somewhere that power input issues, so I tried unplugging and put the adaptor in different socket. the things went further bad.
now i cant turn on my ps4 pro at all, power button stopped responding, i can’t turn on using my controller (tried both wired and wireless).
I was using a ssd, so I tried replacing with original HDD as well. same behaviour.

I thought my ps is dead, then suddenly i clicked on eject button and it gave 2 beeps saying no disk in bay. so i tried inserting a disk, and my ps4 pro started to boot and again it went into safe mode loop, like earlier.
So I am not sure what is the problem is, is it anything i can fix or hardware issue.
Any helps on how to proceed further is highly appreciated .

I’d like to replace it, problem is I’m not sure what ribbon cable it is. Any suggestions / clues?
