Poor Panasonic Customer Service Resulted in Product Return

Summary: I purchased this Panasonic TC-P55GT50 3 weeks ago. After installing it, I found that the TV speakers would intermittently lose most of their volume and the sound quality would degrade singificantly. The problem happened for both cable TV (RG6 cable) and from the attached DVD (composite video). I changed cables and tried different cable/DVD devices, but when the TV warmed up, the sound would get very poor.
