Customer removed battery before sending the board in.<br /> <br /> Cleaned the board and jumpered a bad trace to fix the calendar problem. Board was stuck in a reboot cycle. Repaired another dead trace in the battery section that was sending power to a 74HC32 as part of the circuit for the enable lines on the Backup RAM. Replaced the missing battery and tested.<br /> <br /> ----<br /> <br /> Symptom: Garbled audio<br /> <br /> The audio wasn&#039;t muffled but rather was garbled in the digital section of the board. Soldered over several scratched traces to protect them and checked the DAC and looping Op-Amp IC connected to the DAC. Found the battery had leaked. Cleaned the board, resoldered 2 corroded plate thru to trace connections to fix the audio, and replaced the battery. <br /> <br /> [[Category:Repair Logs]]</div>
