Hi everyone, I hope you are well. Well, what happens is that I got a Panasonic device because the owner had it shut down and the light went down and when they turned it on, nothing dead, well I checked it and found the integrated ones damaged: IC5799 (MIP2F20MSSCF ), IC5701 (STR X6729) and IC5801 (TL431C) and diode D5725 (B0BC6R100010), check other devices and found nothing short or open, proceeded to replace damaged circuits but the source does not start, checking I saw that diode D5798 B0EAMM000057 suffered a burn result of the burn of pin 5 of IC IC5799 (MIP2F20MSSCF) and although it seems to be in good condition I would like to know that diode can replace it because it could leak and I have not found much or no info of this diode , thanks any recommendation on how to proceed I thank you very much.
