So just over a month ago i pulled apart my playstation to clean it i then proceeded to put everything back as it was and it wasn’t working (my step father pulled the little plug thing off the mother board but we got it soldered back on) and i tested it once we had the little thingy back on and my playstation beeped once and the blue light came on for exactly 2 seconds and turned off, i have since then bought a replacement power supply and that still hasn’t worked i have not replaced the factory thermal paste but the playstation was fine the day i decided to clean it so if anyone has any idea’s how to fix this please contact me
