If I would have taken the time to search all the c-net forums I would have saved some time for everybody. It appears to be a problem with a seal on the power supply board or transformer. Thanks for looking!
I bought this tv Dec07 I love it but I am experiencing a loud ringing noise while watching. I dont think it is an audio issue its happening whether im watching dish or ota signal. Im hooked up with hdmi cable for video and optical for audio through my receiver. When watching OTA signal i use my TV speakers. This started about a month ago it may be getting progressivly worse. Thanks in advance for any help.
