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 🙏

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?

I’ve already ruled out the Ethernet cable by testing with another one, and I’ve seen others report similar issues online without a clear solution.

Side note: my HDMI port is loose, and I have to angle the cable for a stable display connection. I’m wondering if there could be any relation between the two issues maybe heat, board stress, or internal damage affecting both ports.

Would it make sense to replace the HDMI port first and see if that resolves the LAN issue, or is this more likely related to the Ethernet port or its solder connections?

I don't know much about ps5 but I did opened up laptops for a bit before. Any insights would be nice, thanks.

Update: Apparently it was sent for service, cleaned and got liquid metal reapplied. Still worth it? Could it be that it was just a shoddy service job? The issue is a recent event after the service.

Recognizable discs: All PS4 version game discs work fine, such as Cyberpunk 2077, inFAMOUS Second Son, Monster Hunter World: Iceborne. PS5 version discs like Elden Ring: Nightreign and Demon's Souls Remakes are also recognized.

Unrecognizable discs: PS5 version discs such as Kingdom Come: Deliverance II and Gran Turismo 7.

I am certain the game discs are brand new, and the discs are placed correctly.

Symptoms of unrecognizable discs: low rotation speed, repeated startup attempts, and continuous beeping alerts.

I have tried resetting the PS5 and rebuilding the database, but it did not help.

I also disassembled the PS5 disc drive and cleaned the laser lens (almost no dust was visible), but the problem persists.

I feel that the optical drive cannot recognize game discs with a capacity exceeding 50GB

So what should I do?

Pressing the power button the first time causes the console to beep and nothing else. Pressing the power button a second time has it appear to attempt to boot up. You can hear the fan and disc drive. You'll see a blue light for around 5 seconds, then it'll become a white light for around 20 seconds, and then the console powers itself off.

During all that, the monitor does not have a signal.

Holding the power button for Safe mode sometimes does work. When it does go to safe mode, pressing many of the options shows the screen freeze and turn off after a few moments. When holding the power button doesn't go into safe mode, you'll hear a first beep after holding the button for 7 seconds, then a second beep after 7 more seconds, then after another 7 seconds the console automatically turns off.

I've tried unplugging the console for a few minutes.

I tried a different wall outlet, different power cable, and replaced the PSU with a new one.

After the HDMI replacement and Liquid metal re-application, the Front USB Panel stopped working. I Chopped it up to a preexisting issue at first. unfortunately, after 2 more HDMI replacements, all the devices are experiencing the same problem. I have fully disassembled, and re attached all flex ribbons and boards, and the issue persists in all instances.

has anyone else experienced this? Is it something i did incorrectly? can i prevent it in the future? and is it fixable? thank you.
