Please help. I have a MRX-130. It worked on the AUX, and Phone settings. LEDs on the buttons lit up. FM and AM did not work, no sound at all, the Display showed zero. I purchased kits from Les (Circuitsandconcepts) and installed new caps on the main board, Les' regulator, and a new Trip Cap in the sandwich stack for the display. I installed all and triple checked the solder for errors. When I powered it up with input to the AUX it sounded great and the power on light at the bottom of the display lite up. However, now I had no display at all and the selection button leds are not lite. I can not change to any other inputs. I have triple checked all solder, I have checked with my in-circuit tester all caps. I went to "thecarversite" and have not found anything that can help me. I checked a few voltages:
On the Preamp, TC9152
Pin 24: +14.7V
Pin 12 : – 15.0V
On the tuner TC9147 pins.
Pin 42 and 41: 5v
Pin 34 and 35: 1.802V
I do not want to trash bin this receiver. I restored one a year ago and it was really nice. Any suggestions would be greatly appreciated.
