Sounds like you have a bad amp IC or transistors.
When these go bad they almost always put roughly 40 volts dc from the amp power supply to the speaker terminals. The protection circuit senses this dangerous (to your speakers) dc voltage and disconnects the speaker terminals from the amp via internal relays (the ones you hear click) and puts it into protect mode. If it didn't the dc voltage would quickly toast the voice coils of the connected speaker.

Hi. I have rxv773 and it had the same problem. If u turn it on and after reley clicking 2 times fast and 1 time after about 8 seconds, look at the display if you see speaker ikons. If u don't see them and there is no sound. You wait those 10 minutes when sound comes back and look if the icons apear at the same time you got sound. If that is the case, you have bad DSP chip inside on the hdmi board. You could open the yamaha cover and see it right away on the top board at the right side. The chip is D80YK113CPTP4. That is the bad one. If you apply a heat for about 20 to 30 seconds with the heat gun at medium settings, you could fix the problem for a day or two or maybe a month. You need to replace the chip with newer one D80YK113DPTP4 . That dptp4 is updatet chip from cptp4. You can find those on aliexpress.

Unless it has fuses, you could have blown any component on the board. If that is a power supply on the upper right, look in there for a glass fuse. If you can't find a fuse, you need a Yamaha Audio Service Centre as they have the test equipment and access to the ICs and other components. Repairing audio equipment is no longer possible with a tester and a soldering iron, you need oscilloscopes, IC testers and other test equipment, plus a full schematic and the knowledge to read it..

never had a cap that would fix itself been doing fixes with electronics for 60 yrs

Here's the manual; http://www.yamaha.ca/av/PDFs/Manuals/2004_receivers/HTR5730E.asp See if you find a solution in there - if not please ask again and we will see what we can do :)

I signed up as your thread is one of only a few visible in a google search for YSP-1 max volume static burst fault. I just changed capacitor C73 from 330uf to 470uf (I ordered a pack of a load of 50V 470uf caps off amazon and a cheap soldering iron kit) This is the first thing I ever soldered in my life and it was so easy. Screws off the backplate, screws off the 2 little plates on top of the soundbar, screws out of the silver frame and flip it out up and towards you to reveal the power supply and C73 is right there well labelled with a line on one side indicating which way to solder the cap, snip off the old cap and solder the new one on. Perfect fix for all static and power on issues on YSP-1!!!!

Check for problem in fuel system - bad fuel - filter - carb/throttle body etc

Blown output stage, blown fuse, speakers not plugged in etc

On Yamaha's official website then for the remote that you need.

Power supply failure

Your question makes no sense.

Check there is mains power still at the amplifier/receiver. Display?

I have seen several things that can cause this. One is a capacitor that holds the memory in the cpu. Another is a voltage regulator and then there are failures in the final amplifier transistors

Unplug all your speakers and components. Then turn on, if it still locks up you have one of maybe 5 safety features hooked up that are built in to stop your amp from blowing. You will need to replace board or have some cool tech dude desolder and isolate . Look for wiring diagram for safety shut down system. Sorry but if it doesn't do it after you disconnect every thing then check each speaker with ohm meter to read factory specs.

Yes but only limited functions! like Volume and on and off.

1. Open internal fuse 2. Power supply failure

T-85L is a component of a hifi system not suposed to work alone. You have to connect it to another Kenwood component (an amplifier like the A85 ) through a special cable to power it on/off. The special cable can be used point to point or as daisy-chained.

Either you accidentally turned off the centre output or something inside has died. I suggest you read the user manual for a start...
