YAMAHA YSP-1 SOUND PROJECTOR- LOUD STATIC NOISE FOR 30-60 SECONDS


had the same problem. Called Yamaha tech, They said try unplugging it it from the wall for at least an hour. That worked. Then it came back. My son the geek unplugged the cable where it goes into the unit and plugged it back in. Problem went away! So.... methinks it's as simple as keeping the contacts going into the wall outlet AND the plug going into the unit CLEAN. Here's a link on some good ideas on how to do that: http://www.naxja.org/forum/showthread.php?t=15476

Picture setting regularly changes to dynamic from standard


You need to change the option throgh the service mode.
You can not access that mode without permission from Samsung.
better to contact Samsung call center.

Sony kv35s66: No picture, just sound and red blinking


This should be a quick fix. Try resoldering the vertical IC. This is a small flat IC attached to a heat sink with about 11 pins. It should be marked LA7837 or something similar. That should resolve the problem.

Keep us posted.

Whining noise


The problem i had was when i would play my tv. I had it hooked from my dish to the sony then the tv. When i played a dvd,cd or the tuner it didn't make that noise. It seems my video/audio 2 channel was going bad. I disconnected my rca jacks and used the optical audio connection. The noise stopped and i got a better quality sound.

hope this helps
