Sadly I do not do any repairs at the moment.. too busy with budilin TF1260s and doing PCB swaps.
that 74F74 on pictyure above only handles cpu clock. RTC is at other side of the board, the OKI Chip.
check that the positive side of the battery goes to the bottom pad of the 1K resistor right of the 32768Hz oscillator (and the cap that is on the outer end of that block)
top pad of that 1K resistor shold go to pin 18 of the OKI chip.
