LG 50PZ750-UG loses menu settings when unplugged.

[bdorset]

This Plasma TV loses its menu settings whenever it is unplugged for half an hour or more. TV goes back to initial setting from factory, asking to choose language, country etc. It does this every time the TV is unplug for several minutes even after I go through the process of initial setup. I attach a photo of the mainboard. Any suggestions?

Not retaining settings. For some reason IC1702 comes to mind. But have no idea honestly just a quick guess. I'll let the more knowledgable folks chime in on this one.




I will say probability is high considering winbond is flash memory nand tech.

It looks like the user adjustable settings are stored in IC601. Is that correct? This set has several eeproms IC103, IC601, IC802
