Try this:
POWER SUPPLY
Check F601. If open, check D602 thru D605, C601, C604, C605, C606, Q402, and IC601. Apply 120VAC and check standby voltage 5.2V at the emitter of Q622. If the voltage is incorrect or missing, check D621, D623, and Q622. Turn receiver on and check for 130V at pin 4 of IC601. If voltage is missing, check IC601, Q621, Q623, RL601, R601, and D602 thru D605. If 130V is present, refer to "Horizontal" section of this Troubleshooting guide. |
