Panasonic SA-AK640E - 17.2. (A) CD Servo Circuit; 17.3. (B) Main (Tuner) Circuit; 17.4. (B) Main Circuit; 17.5. (C) Panel Circuit

IC, LSI and VLSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care during repair.
- Cover the parts boxes made of plastics with aluminium foil.
- Put a conductive mat on the work table.
- Ground the soldering iron.
- Do not touch the pins of IC, LSI or VLSI with fingers directly.
