Can I try this method for a possible solution in my ps4 pro?

i have a problem with a ps4 pro CUH-7115b, which when turned on shows the blue led and a beep for a second and then turns off. It does NOT give a chance to put it in safe mode. I have tried everything from opening it and changing thermal paste, cleaning all the dust, letting it rest for 1 week without power, etc.

I have read that some users have temporarily fixed the problem by opening the power supply and bridging the 5v pin. and the standby pin of power supply then, they connect it to the play4 and with that, they get to turn on the console , the disadvantage is that since it will receive 12v constantly, because when turning it off, they must disconnect it from the current when they are not using it. I want to try this method, I don't lose anything by trying, but I don't know how to make a bridge, could you help me?
