Is this a 100Hz artefact?
Hi!
On my Sony 29" 100Hz (KV-X2993E) television i see some brighter bars scrolling across the screen. This is most visible when watching DVD, and the bars stops in position when i pause the movie. The bars aren't visible in every scenes and they follows the contain of the picture. Is some kind of artefact of the 100Hz process, or is my tv mailfuctioning? |

Does the TV have that problem with any other device? If not, then its the DVD player. Try a cleaner disc. Lanzar wrote: Hi!

It seems to have it with all devices, and whit its own tuner too. It
can also be seen sometimes besides the OSD-menu , but it is most visible with the RGB signal from the DVD player. I have tried the DVD player on another set and it worked fine. I have also tried another DVD player but the problem remained... "PainintheAmp" wrote in message roups.com... Does the TV have that problem with any other device? If not, then its the DVD player.

Have you tried a better quality cable between the dvd player and the set? I`ve seen problems like that when using 'budget' scart cables. Ron -- www.lunevalleyaudio.com |

Ron Ohh just remembered, spent ages once looking for the cause of light patterning and a slight but annoying buzz on the sound of a Toshiba widescreen once. It turned out to be field from a cordless phone base nearby. I`ve seen the same thing from mobile phone chargers.

Intresting answers. I tried a diffrent cable but no change. I have
also tried the input on the front of the tv, but same problem. I also don't think it can be caused by some nearby electronics, becouse the patterns freezes when i pause the movie. Also when i zoom a picture the patterns are visible on different places, and moves when i zoom out the picture... |

Try relocating the dvd player, turn it through 90 degrees, if it`s directly under the set, try moving it away as far as you can.

Same thing. I think the problem is inside the tv. But what could be
failing that creates a problem like this..? |

It had a problem with cold soldering on IC1501. Could that have
damaged the IC somehow, and maybe it should have been replaced...? |
