    I was just about to mention that PSU was coming up VIZIO. 102K, 1Kv are the markings on that cap C504A or C604A?

    Have a look at this photo, pretty clear.http://www.shopjimmy.com/vizio-080gl...-led-board.htm

          The resistor probably went short and gave too much voltage to the cap, causing it to pop, and then short, and when it went short, it blew the fuse.
          Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

          Asus Q550LF (Old main laptop, 2014-2022) - Decommissioned and stripped due to a myriad of problems, the main battery bloating being the final nail in the coffin.

            It is the high Voltage snubber ceramic cap for the PFC MOSFET, it is connected between the S and D pin of the MOSFET, ceramic cap fail's mode is shorted circuit., common failure in other power supply boards too.
            Best to go with higher Voltage than 1KV.
