Sony KV-27S65 27" Television suddenly has very low volume

My Sony KV-27S65 27" Television suddenly has very low volume even when set at full (all bars full). Also, the picture has wavy verticle lines. Could it just use a blowing out (dusty or dirty connections)? Your advice would be greatly appreciated. Thanks...

    Thanks for your solution to my Sony KV-27S65 television problem. I have read about this common problem. I am a little confused about the tuner/IF module locations. My set definitely has two separate modules. I'm guessing the IF module is the one buried further inside the enclosure. The adjustment holes do not seem to be labeled on either, as far as I can see anyway. Also wondering if these modules pull out, or if they are soldered in. I have also read to ONLY adjust the "descr" screw, but am not sure. Also wondering if there is a simple diagram available of these modules. It's a little tough trying to make adjustments when you don't have a clue of what's what. Thanks again for your reply!...

    This set has dual tuners, which have 10 holes with adjustment holes each. They are unmarked, and I don't want to just start turning screws without knowing what I'm doing, of course. Would you know of a diagram which just simply shows the schemtaics of the tuner layouts and adjustment labels? I'd like to try some adjustments if it is possible on this set. Also, there is no change in the very low maximum volume level and wavy verticle lines when inputing my Sony RDR-HX900 DVD recorder through video 1 (RCA cable). The picture is perfectly clear, however, when inputing video 2 through S-video from the DVD. The maximum volume level remains very low regadless. Any further help on this (common) problem would be greatly appreciated. I could send pictures of the board, etc. if i might help. Thanks...

I got a problem my tv sony trinitron kv-xg29m20 the problem is when the tv comes on the picture is not full the sound comes then suddenly its cutsoff and the redlight flashes


By not full I assume you mean the picture is reduced in size all round. If this is the case then you most likely have a power supply problem. Check the HT voltage, if this is low then check all electrolytic capacitors in the power supply for reduction in value.

Low volume on Sony Trinitron


There seems to be a failure in your output drive circuit.
All electronics fail suddenly and don't show any signs until the defect is noticed except in the cases of intermittent troubles From what you have described an intermittent defect is not the culprit here. Are you using external speakers or the internal ones in the set? If you are using external speakers disconnect them and see if the internal speakers work OK. If it's both channels at the same time it's in the electronics, not in the speakers. This would require internal service. Unfortunately there is no easy fix for that. Have it diagnosed (which they can't properly do in your home unless it's a very obvious problem) get an estimate first. Those sets are very well made and reliable but nothing is perfect. You need a service call or move it to a shop.

Volume gone mad


Is there a ceiling fan in the same room? Under the right conditions, light reflecting off the whirling blades hits the TVs sensor at just the right frequency, causing mysterious things like this. Try covering the infrared sensor on the TV (it should be behind a red transparent piece of plastic somewhere in the front. If this keeps it from "going mad", then something in the room is to blame. If it still does it even when the sensor is covered, then it is the TV. Good luck, and let us know what you find!
