Hi.
We have a GE CTV model 29GS6AH in for repair that needed a flyback
transformer ( got it from WES ), all is well except the sound cuts out at
irregular intervals for a second or two (sometimes three to four times in 5
min) on any channel and AV input.
The mute line (uP) stays low, the only difference is on the audio output
pins 28&29 of IS40, where the voltage drops like turning the volume down or
changing channels.
IS40, MSP3410 has been replaced and also the crystal QS40 (the osc amplitude
seems to vary from 3Vpp to 1.5pp, but can be anywhere & doesn't seem to
effect the sound).
Thank for your help.
