Check the current consumption
with Power supply
current < 1A (MAX)
Yes
Check the waterproof sheet's state.
If It is OK, disassemble the PBA
and check the current again
Still problem, change the PBA.
Check the oscillator clock waveforms.
32.768KHz : OSC501(C569),
19.2Mhz : OSC500(C576)
Check the OSC500, OSC501 (Crack, open etc.)
Check the output clock waveforms and frequency.
