Translation:

My PS4 isn't reading the disc.
When I insert the disc, a gray disc icon appears on the screen, and it says "Unrecognized Disc."

The original cable has this printed on it:

SUMITOMO-G [RU] AWM 2896 80C VW-1 -F-

I cannot find a ribbon cable that is the exact same. Can I instead buy ++this one for example++.

The motherboard model is an NVG-004.

It was suggested I try taking components from a PS4 slim, but the slim model’s components are larger than these, and I have yet to get access to a junk PS4 pro board.

Any help would be greatly appreciated!

Edit: i should have clarified this before but it does actually seem to enter safe mode because the light turns white.

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.
