    Samsung PS51D6900DK Flash Nand Chip IC1302 Question

    Hi, I obtained a big Samsung ps51d6900dk TV today which would switch on, display the Smart TV logo, then start cycling on and off.
    I froze IC1302 flash chip to see if this was the fault and the set stayed on. That was several hours ago now and the TV is still functioning correctly. I can turn it off and on again and it stays on every time.

    Now, my question is.. have I fixed it or is it inevitable it will do it again sometime soon? Also, while it's working, if I upgrade the firmware will that help prevent the fault returning?

    I can see these chips are available on ebay for around 60. While that may or may not be worth it for a 7 year old tv, I'm just not sure my soldering skills are up to such a job. Can anyone give any advice?
    Thanks!

    In my professional experience once these flash memory chips start to fail they will continue to fail subsequently, that said if the set is working at the moment you should be able to read the contents of the chip while it is working and program the replacement, you will need to remove the chip and use an external programmer to accomplish this.
