Hopefully someone can help me -- I've been searching the internet for hours for an answer for this problem. I just bought the Panasonic-TH-50PX60U & the installers (very hastily!) "half-hooked" it up for us (no tivo hookup, no surround sound, etc). But I believe when they left, they did have the DVD player working (via a 3 component cable hooked up to the TV). But shortly afterwards, the DVD player began playing only in black & white, with no sound at all -- just buzzing. I disconnected it and connected instead to our Humax Tivo unit -- same exact problem. We bought a new 3 component wire thinking that was the problem -- but the problem is the same with that wire. Is it possible our plasma TV is broken and needs to be replaced? DVD's do play properly when connected via s-cable -- but we're not excited about losing video quality & can't understand why the 3-component cable isn't working. After the installer left the powerstrip fell out of the wall & everything had to be restarted -- don't know if that relates or not. Thank you kindly in advance for your help.
