Troubleshooting

6-3-7 When the remote control is not receiving.

1. Check the remote control quality with a remote control receiving tester.

2. Check if the connector was normally assembled.

3. Put the set in operation and check the voltage of No. 1(+) and No. 3(-) of the main PCB CN 94 while operating the remote

control. When the voltage descends below 3V, the assembly module PCB is normal and the main PCB is poor. Then replace the

main PCB.

4. Replace the assembly display PCB because the module PCB is poor if the voltage between No. 1, 2, and 3 of CN 94 maintains

5V after the remote control starts operation.
