I pulled a 195 lightbox in from field, when I was at customer's house, no audio, appeared to be in mute, output stage was functioning, as you tried to increase volume you could hear what sounds like lpf circuit changing voltage levels(popping as sound is increased), now in shop set has functioned flawlessly for three days, I know the 203 has software issues but I have never encountered this on 195,any help would be greatly appreciated. charles betzler Best Electronics repair1@xxxxxxxxxxxxx ------------------------------------------ Make your TechAssist database better!
