Sony TV sound problem. Advice?
I have a standard type 27" Sony TV, about nine years old. The sound quality
has been poor for about a year now. Some channels especially sound kind of muffled, and the volume varies up and down by itself. Seems very strange! Someone told me that there is a component in the TV that can go wrong and it governs the sound signal somehow. Is that the case? Can anyone confirm that for me, before I take it in to the shop and maybe get a song and dance? I would like to have an idea if it is fixable before I leave it in the hands of a repair shop. |

The last Sony TV I repaired with a sound problem turned out to have a bad electrolytic capacitor in the audio section. As you may know, electrolytic caps can leak and dry out. Another common problem I find in electronic equipment is cold solder joints. A cold solder joint may not cause a problem until years after the product is manufactured. [8~{} Uncle Monster |

Could be anything from the tuner through the audio decoder to the audio amp.
Due to the set's age it is highly probable the set has the famous audio decoder assembly that has been notorious for causing audio related problems. "Uncle Monster" wrote in message ...
