Question about Sony FD Trinitron WEGA KV-20FV300 20" TV

1 Answer

Volume gone mad

I have a Sony television model KV-20FV300 that has a mind of it's own. Last night the remote would not work, I tried new batteries, no luck, so I got up and turned the set on the old fashioned way. About an hour later the volume bar appeared on the screen without warning and the volume maxed out before my eyes! I removed the batteries from the remote and unplugged the set overnight. The next day I plugged it back in and from the front panel of the television set I was able to lower the volume using the buttons, but as soon as I realease the button the volume climbs up to max again! Does anyone have any ideas? Signed, Needs Earplugs

    Good news....while covering the sensor as suggested, and holding down the volume button to save my eardrums, I was able to depress the tv/video button which cycled the tv mode through component1 component2 etc and back to tv mode....and wah lah!...the volume stayed low....the tv now works like a charm again, even the remote works. I have no idea what it was that was wrong, or even more puzzling...what it was that remedied the problem, but thank you very much for your help!

    I have the same problem.  The tv pays no attention to the remote or the buttons on the front panel.  Sometimes the volume will not change when I turn it on, but as soon as I touch a volume button on the tv (not the remote) it kicks into "increase volume" mode.  In this mode, the down volume button on the face does decrease the volume.  No other button works.

    This first happened a few weeks ago, and cleared itself up the same evening.  The latest incident started last night and has not cleared up.

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!

I was given a tv by sony kv 20fv300 it was working fine last night and I tried searching for codes so that my directv remote would work with it. Now it has lost the picture and on the snowy screen it says...

It's likely that during your search you switched to an alternate input which has "no signal" accidentally. Open the menu and select the input that is associated with where your cable/cables is connected.

The owners manual for that model is available online for free! Go here and download or view the manual for your particular set.

I am sure that would be helpful for you in any case.

Sony KV-24FV300 changing video input by itself - possessed?

It sounds like the tact switches (on the control panel) are defective.....This usually happens after some one cleans the screen with a spray and it drips onto the board, Or they went bad on their own.
