Have you done what is recommended on page 87 for "no sound from the subwoofer"?

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.  

C515 ON THE MAIN POWER PCB (HAS 223 K 630HI PRINTED ON IT) HAS FAILED
Replace with a 22nf capacitor - Maplin part number N38CN -
the new maplin part has a higher voltage rating and is bigger. it will need to be fitted with the leads extended with wire to get it to fit.

Yep. There's a modified component needs fitting in the 3 mode standby circuit. Any Yamaha dealer will know what to do.

Sounds like a a pcb dry joint or a poor connection on a multiway plug / socket.

try removing and refitting all the pcb plugs - better still spray carefully with WD40

Goog luck, Gaz

The best way to get quality sound would be to go through the USB connection of the phone.

It will be hard and a bit costly to get a cable to link the Ipod and projector.

Easiet and economical way is to go to apple and purchase a cable for the jaudio jack at the top of the Ipod that will also have an audio jack connector for the projector

Hi

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

NO!!! get a 3.5 male TRS to stereo RCAs to either the Aux input on the amp or the audio portion of the front A/V Aux. the audio jacks will be red and white.
