Good evening, Was hoping someone could help or offer some suggestions in what might be going on. Had 2 series 1 directivos for the past 3-4 years and haven't had any quality issues. Last week I upgraded to hd and they installed a new dish and the hdtivo unit. One of the things that they did when they installed was to bypass my multiswitch; having 4 lines come down from the dish two now went to the back of the hdtivo and the other two lines were connected to the two lines that went to my bedroom tivo. As soon as the installation and connections were completed I noticed these white lines going right to left on my bedroom unit. Mentioned it to the installers and they claimed it was nothing..it was something to me and they weren't budging (to be honest, they were already here 5 hours and it was late). The lines are now becoming more noticeable and I guess I am too much of a perfectionist when it comes to that stuff. I have swapped out the s-video cables, tried using the composite cables..removed each line from the dish one at a time and noticing that they are both the culprit..not bad when only one is plugged in..but together. Just wondering what might be causing this and if its something I can fix on my own. Thanks for reading. Tom PS. Have noticed since the installation that sometimes the lines aren't as pronounced as others..if that helps.
