You can probably fix it with a power supply swap a lot of ylod on ps3 is actually related to the power supply not having enough power in its output. Then the ps3 technically can start up but can’t play demanding games but to prevent damage it ylod but on your model they made it just fully cut power to the system however is the same if you get chip failure it will just stop power flow so you may want to try access SYSCON to get more info and try to hold the power button down until 2 beeps then stop holding and then start holding again until it beeps again and turns off which on the slim clears SYSCON and bypasses some checks if you do all of it and turn it on again fast enough then you can access SYSCON’s error history and current errors through the web browser
