Question about Sony KV-27S42 27" TV

1 Answer

Sony KVTS27 audio noise and pops

My Sony 27" TV (model KV-27TS27) has low audio level with crackling and popping noise, that intermittently changes from bad to worse. If TV has been turned on for several hours the problem improves some, but still occurs. This noise only occurs when signal is connected to the coax input. When using the RCA input jacks, the audio is perfect. I have electronic technical training but little tv experience. Thanks for any help.

Green screen and distorted picture sound is good but no picture


It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.
