Led Bulb Blinking Problem & IC thermal shutdown (TSD) protection
« on: February 11, 2020, 04:58:54 pm »
This specific G4 Led bulb starts blinking after almost 5 years of work.

Checking the components in the PCB, everything seems to be OK, except the LED driver ( PT4115 ) where the built-in thermal shutdown (TSD) protection system shuts the functionality of the IC to protect it.

So my question is if the PT4115 IC Led Driver is now almost dead since its itself protection system seems to be malfunctioning after all these years of working or if there is another reason that causes the IC to over-temperature and that I should look for.

Thanks
