Question about Sony KV-20S10 20" TV

1 Answer

Picture intermittently drops out.. other problems

My old set, while still in great condition, has a few problems that have developed in the last few years. 1. The main problem, is that most times the tv gets turned on (receiving via antenna on coax) the picture will break up, with white lines flashing across the screen and static bursting simultaneously from the speakers (see it on youtube: ). This only occurs when using the tuner, and stops after the set has been on for 10-15 minutes. 2. The composite video input is flaky, while it's in use I'll frequently have to get up and use the input cable as leverage to "bend" the jack either up or down until it comes back. While it seems likely that this is a bad ground or broken solder point, I'm fairly certain that at one point I had resoldered everything and it didn't make a difference, so any other ideas would be helpful. Does anyone know if it's possible to add an s-video input? The next model year's set has one, but this one does not. 3. Power switch is faulty - I hear this is a common problem, does the switch need replacing, or can it be repaired? 4. Sound seems "quiet/hollow". The volume needs to be set much higher to be audible than when it was purchased, and it sounds a little tinny. But speakers themselves seem fine, could this be a dying amplifier or something? If anyone has any suggestions for any of these issues please let me know, I'd like to fix it myself if it's not going to cost much for parts. Thanks!

    while i agree that that would be the easiest solution overall, it doesn't really make sense financially. my pc is in the same room (and has a bigger screen + home theatre system), so all the television really gets used for is playing old video games, or watching random tv. i have a tv card as well, so i could even get rid of it altogether - but there's just something about being able to just turn it on, rather than booting up the computer and fooling with the settings etc.
    it's a great set though, and it's a shame to see all these small problems crop up and not know what the causes are. i'll probably get around to figuring the jumpy input out, but the tuner and audio issues are beyond my current abilities.

Tv pricing has come down quit a bit these days and like the typical computor printers the ink cost more. In your case the parts will cost you a lot. With all the problems discribed "buy New" and get yourself up to date with that of what you want a Tv to do for you.

Rear projection 48 inch mitsubishi. Actually intermittantly goes blank, then back to picture, every few seconds. Not sure it's worth repairing, although it's been working well for a number of years.

A number of things will cause set to go "blank".

The most common problem is sets like this develop bad solder connections which is normal from age etc.

Provide me with exact model number so I can assist you more. You do have to be careful fixing a set over 10 years of age as some parts are no longer available.

These sets are very well protected, if a vertical problem where loss of picture, the set will blank all three picture tubes to prevent a line or spot being burnt into all three tubes.

The more you tell me the better I can assist you---model number and year set made will be on the back of the set.

Green Screen

Do you just have a completely green screen, or can you see a picture or On Screen display when selecting inputs and channels? And did this problem develop after moving the set "with great care"? Knowing RCA's reputation for building sets that develop intermittent connections after a few years, I would be tempted to look there first. Semiconductors and IC's have been very reliable lately.

Intermittent loss of sound

hpesoj the problem comes from the satellite in the sky, too many bits of data for your chassis, only fix involves adding a capacitor to the microprocessor, note that if the modification is done your closed captioning will no longer work, but it`s the only thing that will stop it other than un-plugging the ac cord waiting for a short time and then re-apply the cord, which you have already found out, any local tv tech should be aware of this "so called fix" give them a call, good luck, BMW Rider
