I’m currently performing a deep thermal maintenance on my launch-day PS5 (2020).

For a long time, I've dealt with fast heat-up times and the "LAN Cable Disconnected" error that triggers specifically when the console gets hot.

(note: I am not an expert and before I started I did some research (YouTube, Reddit, iFixit, Gemini) and I want to share what I found.)

Upon teardown, I confirmed "dry spots" on the APU (Liquid Metal oxidation/shifting). I have already reapplied the Liquid Metal, and now moving on to the thermal putty phase.

I want to go beyond the factory application of thermal putty (by adding it to more areas) to achieve better heat dissipation to the shield/heatsink.

I’m planning to use the Upsiren UTP-8 thermal putty.

To solve the LAN disconnects, I intend to bridge the gap between the Ethernet port housing and the main metal shielding with the thermal putty to help sink heat away from the controller chip.

Q:

1. Looking at the marked images, are there any risks of "over-padding" specific areas that might prevent the plates from seating flush?

2. Has anyone had success specifically using thermal putty to stop the Ethernet port from overheating?

3. Are there any "hidden" hotspots on the 2020 model I should hit while I have it open?

Hoping this helps anyone else and I will be sharing my results after a few months from now. Thanks in advance 🙏

I got this unit from my friend and lets just say that the insides are in... suboptimal quality to say the least. most screws are loose/missing and the heatsink retainer was installed backwards etc.

if anyone can tell me the solution to this, it would be GREAT.

Edit: turns out i need to tension the back braket, and while doing so, the unit stayed longer on, the light turned from blue to white, and then red with 3 beeps, and off

Thanks!

It turns out, that the APU heatsink tension thingy at the back was not tight enough, the unit works fine after tensioning it.

but it seems to have done more harm than good. I was going to try to fix it myself.

I've looked at the card under a microscope and unfortunately it doesn't look too promising (possibly damaged pads/tracks).

Has anyone here had a similar problem or think it can be saved?

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 am stuck on this screen. I have tried four different cables, went out and bought a new one, three different controllers, tried the reset button, clearing the cache, but it will not connect. The USB port works because it charges my phone when I plug it in. Any help would be appreciated. Thanks

Translation:

Only a blue light comes on, no white light.

When I pressed the power button, the PlayStation started up silently, stuck on the blue light. I had to hit it or fix it and turn it on a few times before it started working.
