Hi guys, y have a Hitachi that is having sound problems. When you power on sound comes on at times and at times it does not. When it does come on after about 20 seconds it the sound cuts off. From advice of Fletcher site I went ahead and performed correction for multiple sound problems. Problem still persists. I have also replaced the Sound amp chips and had no success. I checked solder joints and all look good. Unpluged speakers one by one and problem still present. If anyone has seen these problem I would appreciate any assistance. Wiring already checked. Also used freeze spray for possible heating of ics or other components and no change.
