TROUBLESHOOTING

1. One of the most frequently occurring problems is

poor solder connections.

a) Tug slightly on all parts to make sure that

they are indeed soldered.

b) All solder connections should be shiny.

Resolder any that are not.

c) Solder should flow into a smooth puddle

rather than a round ball.

Resolder any

connection that has formed into a ball.

d) Have any solder bridges formed? A solder

bridge may occur if you accidentally touch
an adjacent foil by using too much solder or
by dragging the soldering iron across
adjacent foils. Break the bridge with your
soldering iron.

2. Be sure that all components have been mounted

in their correct places.

a) Be sure that diodes D16 - D24 have not

been installed backwards. The band on the
diodes should be in the same direction as
marked on the PC board.

b) Are electrolytics C1, C3 - C6 installed

correctly? These capacitors have polarity.
Be sure that the negative lead is in the
correct pad.

c) Be sure that the ICs are installed correctly.

The notch should be in the same direction
as shown on the top legend of the PC board.

d) Be sure that the LED has been installed

correctly. The flat side of the LED should be
in the same direction as marked on the top
legend of the PC board.
