Question about Kenwood VR-7070 Receiver
I have a Kenwood krv 7070 receiver that I never had any problems with. My wife accidentally plugged it into a outlet I was working on that had reverse polarity. Now nothing comes on. Not even the little red standby light. I checked to see if power was comming through by plugging an appliance into the two power ports on the back, and nothing happened. I found nothing wrong with the cord and all the fuses are still good on the inside. Do I need to send it in or do I need to buy a part for it?
If the voltage was 110, the polarity should not have made a difference. In all probability, the input power transformer has an open primary. This can happen with a power surge or just because of age. If you have an Ohmmeter, with the unit unplugged, measure across the 2 input pins for the main transformer. It should read about 3 ohms or less. If it reads infinity, it is open and must be replaced.
Keep us posted,
