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

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

We now use a cable service with this TV. The video input (source) continues to change on its own. We can manually change it back via remote, but it cycles through again. I've already tried changing batteries.
I've read elsewhere to try changing the signal source on the TV - how is this done? Thx!

Re: Sony KV-24FV300 changing video input by itself -...

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.

Im not sure how to hook the converter box up to it

For a digital to analog converter box, connect your antenna cable to the converter box. Then pick your output connection. Either set the TV to channel 3 or 4 and connect the coax out from the converter to the TV or connect the composite video (AV) to one of the A/V inputs on the TV (change the TV source to the appropriate input). The source is changed with the remote (TV/Video button).

If you have other devices like a VCR in the connection sequence, you could connect the converter box to the VCR (and record on channel 3 or 4) and then connect the VCR to the TV as above. You will be limited to recording and watching the same program unless you get another converter box or tuner.

Programming the remote will depend on the box. For other set top boxes, the connections will be very similar.

I hope this helps.

Cant change channels?

What is your antenna source? Cable or antenna? Try keying in a certain channel on your remote. see if you get that channel. Tv will not auto program if you do not have channel source coming in to antenna input.

Manual donwload

Video input source is changed by the buttons:
1. Video Source
2. Input
3. TV/Video
4. Source

one of those four on the remote some where.

Also, chances are your TV itself will have one of those buttons somewhere.
Usually pressing it will either cycle through the inputs or bring up a selection of them, which is usually navigated by either arrow buttons on your remote or the channel up and down keys.
Lemme know how it goes.
