Battery leak require board level repair
Hello, i recently get Panasonic RQ-SQ20 and try to restore it.
This is what i done so far: When i try to power it up, i don’t get a red light indicator so i try to disassemble the device. Then i desolder the board from the chassis and battery connector just fell off. I solder it back, try to power it up and still nothing. Next, i inspect the board and found it had battery leak corrosion around IC4. Then i try to scrub the board with flux and little bit of solder and some of the copper pad fell off. I tried to connect the broken pad with thin copper wire but still not working.
Here what i know so far: Main GND and VCC is getting around 1V.
What should i try next? I have a schematics but can’t really understand it properly.
PS: I’m doing this as a hobby and not fully know what i’m doing.
