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!!!!
u have a cool sound projector but u have a baaaad power supply system. bad power supply design - u will get all sorts of noise when u power it up. i have a sub woofer with the same problem(which in my case is the way it is designed). i used a delay circuit. but in ur case i know YSP-1 has a clean start up. so, if the warranty still covers it get it replaced. static noises, pop noises are often caused by bad capacitors.
Two possibilities: 1. Your source material does not contain bass frequencies. 2. Your SUBWOOFER SET - BASS OUT is set to Front, rather than SWFR (subwoofer). See page 63 of the manual.
I have the YSP1000 and I had a similar issue but it was less frequent. I located the clicking sound which turned out to be a relay on the main circuit board. Before replacing it I removed the relay cover and cleaned the contacts. It has not miss behaved since and that was some 8 months ago. Give it a wizz
We have the same issue. I owned the unit for about 2 1/2 years before it quit working. The Yamaha YSP-1 has been sitting on my shelf for the last 2 years now collecting dust. If anyone finds a solution, please let me know
