ok. update. TX-48AS640B arrived and working fine
only hdmi tested i dont have aerial at home.
data from last user still in mainboard so did factory reset and now is asking if im in ireland or uk.
anyway to change that? service menu? i still have the broken board i can read and program spi or nand
broken board was reflowed the cpu so the rest must be fine.

ok. finally could manage to test the aerial and everything is working normally. only tested for a couple of minutes. searches and find channels perfectly.

TX-48AS640B main board works perfect in TX-48AS640E model.
