Television and Home Theater

Hi,
My 8-month old Philips 32PT6441/37B suddenly lost its color last week.
Everything else works fine, meaning it works like a Black & White TV now.

Any suggestions on what may be wrong and how to fix it?

I have just about enough expertise to open up the box and handle the soldering iron.

Thanks.

Thanks in advance for any troubleshooting help on this topic.

I recently switched to a prog scan dvd player (Sony DAV-FX10) - hooked up with component video to Panasonic EDTV (TH-42PWD6UY). I used monster cable from the tv coupled to radioshack gold component video cables to the dvd player and noticed these faint red bands (approx 4 or 5, approx .10 inch thick) running horizontally across the screen. The bands were static, faint, and up close appeared to be tiny flickering red dots on the screen - the bands are more easily noticed when the picture fades to black.

My Zenith televisions comes on but only shows a static picture. When I hook my cable box to it nothing happens. Is this a serious problem?
