Troubleshooting

TAS 455 and TAS 465 Service Manual

6Ć45

This procedure assumes that

there is front panel control.

Go to

Part

Two

Measure the power supply

voltages on J67 on the A1

Analog board.

Pin 12

+15V

Pin 10

+8.6V

Pin 9

-8.6V

Pin 6

+5.2V

Pin 1

-5.2V

Are

the voltages

approximately the

same as the nominal

value?

Yes

Turn the power off. Remove

the cable at J67 on the A1

Analog board and check

pins 12, 10, 9, 6, and 1 for

shorts to ground.

Yes

Are any

of the pins

shorted?

Replace the A1 Analog board.

Perform the A3 Display Driver

Board Troubleshooting

Procedure.

Press the

CH1

button

and rotate the

VOLTS/DIV

knob several times in

each direction. Repeat

for remaining channel(s).

Listen for clicks between

some of the voltage

ranges.

Were

clicks heard for

each channel?

Yes

Perform both to isolate

the problem.

Have you

performed both

the A5 CPUBoard and the

A62 Front Panel module

Troubleshooting

Procedures?

Yes

Replace the A1 Analog board.
