After looking into this problem with the tv . :67:

If i short out the eeprom with the two pins . :dubbio: Its back to normal.
Works fine remote and buttons on side of tv.
Its only when i turn it off , i need to short out the eeprom again.
no blown caps or resistors that i can see. volts are fine.
Number of chip looks like EON B32-100HIP.179603Y, 0750GDA.
Hunt is on for a chip now. :72:
