Hey guys! I saved an older Samsung tv from the recycle bin to tinker with as a hobby. Looking for some help as to what else to check/replace.
The issues it had at first was it would randomly reset its picture settings, this slowly devolved into it rebooting itself and the control board becoming unresponsive. Now it has finally gotten to the point where it no longer turns itself on when plugged in, but when I turn it on with the remote or power button it will boot to a blank input work for 15-20 seconds then turn itself off. I found if I pull up the menu it will actually freeze my control then turn off. The time to turn off is semi-consistent.
I have tried reflowing the board, and even replaced the NAND flash chip (ic1302) and the same issue still occurs
. I tried getting into maintenance mode (Mute - 1 - 8 - 2 - Power On) and the issue occurs in there too. Also tried factory resetting after NAND replacement and bridging the SDA / Reset.
Any other ideas of what it could possibly be or what I could try? The Power board's capacitors look fine though I haven't tested them all with a multimeter yet.
Thanks!
