Question about Sony FD Trinitron WEGA KV-27FS100 27" TV

2 Answers

Speaker buzz The left speaker of my SONY KV-27FS100L TV has a very annoying buzz with certain sounds.  I have not played the TV too loud but it sounds like the speaker may be blown.  The problem does not occur all the time -- only with certain sounds -- both during dialog and music.  Is there anything I can do about it?

    I read your solutions and took the back off the TV (mostly). The speaker looked OK, as far as I could tell. I spoke to a repair shop and they felt the problem could indeed be capacitors, as Shuttle83 suggested. I am planning to bring the TV into the shop but I have not been able to get the back of the TV back on fully. The bottom of the plastic shell has spread out and I can't get it into place. I plan to wrap a strap around the bottom and bring it in, unless you guys have another suggestion.

Hello TomMan,
I would suggest looking at the speaker first to see if it is torn, if it is that's your problem, however if the speaker is not torn, you should then use a audio signal generator and an oscilloscope to view the output at different audio frequencies and levels, This will give you an idea about the source of the buzzing sound. Check for bad capacitors, sometimes these can cause problems.

If you do not feel as if you can do these tasks, get a TV repair shop to check into this problem.

Thank you,
I hope this helps,
Shuttle83

Well yes your speaker is damaged, the cone actually has a tear, so audio that has low base or high pitch will cause distoration..

Simply remove it, take it with you and buy a similar one.. Same size, same watts, same ohms and just put the new one in.

speakers are standered only brand names are different..

BTW if you feel that you dont want to purchase a new one, simply stick the tear with duct tape, or you can hot glue it together.. If its plasctic, plastic weld works good(ask for it at a hardware)..

Buzzing sound wyen volume is high.


If you have a cable box on the TV, make sure the volume on the cable box is turned all the way up. If you do not have a cable box, some TV's seem to have a annoying buzz louder than others.

Sound at power on


The sound you are hearing is the degausing coil which will vibrate for a second when the tv is turned on. This part demagnetizes the picture tube and this sound is really quite normal. Depending on the position of this coil it may vibrate against the front cabinet of the tv and may sound loud at times. If this really bothers you then you need to have the rear cover removed and have it repositioned a bit do it won't vibrate so loudly. Or you can enjoy the buzz for the short time it happens and not worry about it.
