No Power - not surge related

Used this receiver one day, the next it was dead. There was no power outage or surge. There is no display and not responding to the remote or switch. Checked all the power components and they appear to be okay. Getting power to the unit, but not going through the transformer on the power supply board. Relay is not clicking, not getting the signal to turn on. I tried to trace this problem, but I do not have the service manual for this unit and did not see it anywhere on the internet. Checked your site and you do not have it, but thought maybe you can help look for the problems. Any suggestions on what to check next?

If We recently learned after a lot of research and trial and error that the solution was in front of me and not on Google all you have to do is enter the back up system and reboot it pressing random combinations until I found the right one unfortunately I cannot provide that combination as I do not remember it. Just try messing with the buttons and see what happens. I hope this helps and of I can I'll try and figure out the combination

teresa, there is an error log that can be run (if you're quick) and a reset procedure.

error detection count - (from OFF/STANDBY state) press & hold [PRESET <–] &[ STANDBY/ON] buttons. Release when the unit powers on. each press of [ENTER] key display a protection error count. DC errors / OVERload error / TEMPerature errors
error reset- (from OFF/STANDBY state) press & hold the [ALC/STANDARD SURR] & [STANDBY/ON] buttons. Release when the unit powers on. The unit will display "CLEAR?" press [ENTER] to reset error and error logs. The unit will respond with "OK".

the other thing you can do, is to go to this device page, scorll down to Service Documents, and download the service manual by clicking on the blue link. you will need both parts for a complete manual. Hope this helps, good luck.

For my VSX-827 your key combination to reset the DC Error did not work. I had to press [ADVANCED SURROUND] and [STANDBY/ON] at the same time for 3 seconds. Then it finally turned on again!

RE: @thasnitch

Is the unit completely off or is there just no sound? It sounds like the amp is in what is called protect mode. Look at the user manual for a description of protect mode. If one or more of the output stages has a problem, the amp will enter this safety mode to prevent damage to the speakers.

I would suggest that you open a new question rather than continue on this one for your specific problem.
