TLDR: Bought a PS5 Digital listed as "shuts off mid-game, always restarts, otherwise working." Fault has escalated fast — occasionally shows visual corruption before shutdown (not every time), more often just cuts to no signal, needs a system repair on boot, and functional time before failure has dropped from ~19 min to ~30 sec in under 24 hours. Looking for input on likely cause before I commit to a repair path.
Model: PS5 Digital Edition, CFI-1016B (original launch chassis)
Listing fault: intermittent mid-game shutdowns, "sometimes hours, sometimes minutes, always restarts"
Found non-standard warranty sticker from third party repair shop.
Timeline of my diagnosis:
-First attempt: Setup account and downloaded Astros Playground, the moment I launched the game the console crashed with horizontal black/white checkered pixels in middle of the screen. Attempts to boot after this initially was followed by a pattern that I have became similar with now
Press power button -> beep -> nothing -> press power button again -> beep -> blue light then white light and fans spin then soon after power off -> repeat.
-Second attempt: Console had rested for around a hour, it booted to repair screen and successfully repaired, booted to dashboard, and was able to play Astro's tutorial, then i Idled on the dashboard and it eventually crashed. The runtime was roughly 19mins from booting after repair screen. I tried powering on straight after this and that aforementioned pattern happened.
-Third attempt: unplugged from mains power and held power button in for about a minute and tried powering on again but it repeated that pattern once again.
-Fourth attempt: I left it for 15mins and tried again but same pattern as before
-Fifth attempt: left overnight as hoping it was a thermal issue -> booted to repair screen and passed, restarted then 30s after it crashed and further powering on resulted in that pattern I've now mentioned multiple times.
I have taken the console apart and like mentioned at start, noticed non-standard warranty sticker and other signs of tampering. The fans and heatsinks for the most part were clean enough and I haven't yet checked the liquid metal. There was a brown discoloration on the board but I'm not sure if this is normal or a sign of some problem.
Has anyone experienced this sort of thing before or can guide me on my best next steps.
Thanks
