Help! Yamaha RX-V690 problem.
I apologize if this isn't the correct forum.
I have had this unit for about 5 years and it has worked great. Yesterday, we had a thunder storm. The unit was not powered up during the storm. The house was hit by lightening. Loss printer, all land phones, GFI, garage door opener and my Yahama stereo receiver. So, I cannot listen to music while I cry in my beer. The receiver was plugged into a surge protector along with several other pieces of stereo equipment. They appear not to have been effected by the storm. The Yahama receiver will not power up. When the power on button is pressed, nothing happens and there is not a sound made. I removed the cover and found three fuses that are all OK. I also checked the switch and it appears to work. However, it seems that no power is getting to the large power transformer. If anyone has any ideas of something that might be easy to fix that is causing this problem, it will be greatly appreciated. Thanks in advance for your help, Bill |

Thanks in advance for your help, Bill The first thing to go in this scenario is the standby transformer. Unfortunately, the second thing is often the main microprocessor. A knowledgeable tech type could sub in a DC voltage at the standby voltage regulator, long enough to see if the micro is responsive. That would at least give a clue whether a repair is feasible, because if the micro is bad, often other audio switch IC's, electronic volume control IC's, etc are bad as well. Mark Z. |
