I had indicated somewhere in another post that my parents went to Best Buy and bought a 50" Magnavox DLP set (50ML8105D) Saturday with a LG upconverting DVD player (LDA-511). After hooking it up for them, along with their satellite box, VCR, Gamecube and Belkin power conditioner, I was getting no audio from the DVD player via HDMI cable. Everything else had audio and video. I figured it may be the DVD player needing a firmware upgrade so I hooked it up with a set of component cables and stereo cables for audio and all was fine. Then the cooling fan started making a grinding noise like it was rubbing something. I checked the level of the TV and it was off just a bit. After leveling the TV, the noise stopped. I've never worked with a DLP and it seemed a bit strange but my folks were willing to accept that if the noise stopped. The next evening, they tried to watch a movie in their VCR and the audio on the Composite 2 input was not working. They had video but no audio. Also, the fan noise started again. The following morning, my mom called me and I went over and checked to see if everything was still connectly properly. It was and the Composite 2 input had audio again. My mom remembered the salesman telling her that if she had any trouble with the TV, Best Buy would send someone to the house to repair it. She had made it clear that she lived over 50 miles away and my dad had heart surgery a couple years ago and was not supposed to be doing heavy lifting. The salesman said it did not matter where she lived, they would send someone out. So she called Best Buy and talked to someone in the service dept who told her that regardless of what the salesman told her, they did not do that and she would have to bring the TV back to Best Buy to have it checked out. At this point I had to leave for work and I told her I would load it up in their truck Saturday and we could take it back and swap it for a new set. It sounds to me like the set was damaged somehow, dropped in the warehouse or banged up in shipping. I was willing to chalk the HDMI problem up to a firmware upgrade but with the other issues surfacing, it appears to be hardware related.
