[PS5 Slim] Infinite Blue Light, No Video, TV Still Detects Console
Hello everyone,
I recently bought a used PS5 with a known defect. I was already aware of the issue before buying it because the price was much lower than usual.
Before purchasing it, I asked the seller some questions. He told me the console had only about one month of use and that the problem was that it would turn on and then shut off. He said he tried to use the warranty but wasn't able to, so he took it to a repair technician. According to him, the technician couldn't find the problem, so he decided to sell it instead of spending more time and money on it.
When the console arrived, I turned it on and it worked for about 2 minutes. After that, the image froze and I had to force it off. It kept behaving like that: sometimes it would boot, but after a short time the image would freeze.
I decided to open it and clean it. The inside was 100% clean and looked practically brand new. I kept testing it a few more times and the same thing happened. Eventually, one time it lasted about 5 minutes before freezing again. After that, it stopped displaying any video at all. Now it only turns on and the blue light flashes forever.
After researching the issue, I found that it could be related to the liquid metal or overheating. So I decided to completely disassemble the console and clean off the old liquid metal. However, since I didn't have new liquid metal yet, I temporarily applied high-quality thermal paste instead. I know this probably wasn't the best decision, but it's the same thermal paste I use on my Intel i9-14900KF, which is a very hot CPU. My idea was simply to see whether it would allow the console to stay on for longer.
I carefully reassembled everything, making sure to avoid static electricity and double-checking all the connections. However, now when I power it on, it only flashes the blue light indefinitely. It's been two days, and every time I try to turn it on, it just keeps blinking blue forever.
Today I connected it to a smart TV, and the TV recognizes it as a PlayStation 5, and selecting the HDMI input automatically powers the console on.
I've already ordered new liquid metal, which should arrive tomorrow. Until then, I've decided not to power the console on anymore. I'll wait for the liquid metal, open it again, remove the thermal paste, and reapply liquid metal properly.
Has anyone experienced something similar or have any idea what the issue could be? Also, could temporarily using thermal paste instead of liquid metal have made the problem worse?
The console is a 2025 PS5 Slim (new model).
Also, the inside of the console didn't look repaired or damaged in any way. There were no signs of burned components, corrosion, or previous work. It genuinely looked like a brand-new console with what could be a factory defect. Of course, it's also possible that the previous owner accidentally caused the problem, but he insists he never did anything to it.
