PRECAUTIONS FOR REPAIRS
1. Check for bad contacts on connectors on the main PC
board and elsewhere by applying hand pressure.
2. Check AC power supply for problems-e.g. blown fuse,
bad switch or AC outlet.
3. Check for intermittents or defective soldering on the
main board by striking the reverse side of the board
gently with an insulated bar.
4. When soldering PC boards, limit the soldering iron
temperature to 500°F (200°C) to avoid peeling of the
foil.
