Adjusting picture of Sony Trinitron KV-20V50 ?

post #1 of 3
Thread Starter 
I have a Sony Trinitron KV-20V50 television, and the picture has a small level of "ghosting" that I can't figure out how to remove. This ghosting occurs with all inputs, including S-video and composite from our DVD player and OTA digital converter box. The ghosting is not chromatic, but is mostly grayish when seen on a white background. Except for the ghosting, the image looks great -- colors are perfect, etc....

I've already tweaked the picture adjustment through the tv menu. I can't find any screws which can be used to adjust the picture in other ways (e.g. horizontal, vertical) like found on the older Trinitron's. (Maybe the screws are there, but if so, they've done a good job of hiding them!) I've even tried three different s-video cables in case it was a cable being funky.

Are there other adjustments that can be made, such as screws inside the set? Or does any further adjustment require a service person? (Our set is probably not worth having a professional service it.)

Thanks!

You might look for a poor connection.

"Ingress" occurs when OTA signals (often channel 5) enter via an poor cable connection.
i.e. the cable for cable tv, satellite, etc. has a crappy connector cable with a tiny bit exposed wire.
That tiny exposed wire acts as an antenna for analog channel 5 OTA and ghosting can occur. Sometimes the poor connection is located in the wall jack for cable tv or satellite. Look for exposed wire somewhere. Check for poor terminations on your various cables.
Also, while observing the ghosting, give all of the inputs on the back of your tv a light jiggle. If that affects the ghosting then look for the problem with your tv's inputs.

jnoring, I see that you are using an atsc tuner for your digital OTA. This in no way excludes ingress as the possible problem.
