In 2/07 I purchased a Mag Innovision MA-32EF1AC 32' LCD tv manufactured 1/07 from Staples. The TV ceased to function last friday after doing a channel scan and then powering down the set. Since then, the set will not power on properly, but instead will power on and produce a humming noise but no display and no response to button input. This is a known firmware defect with this set which is heavily documented by MAG/Proview's customers online. See http://www.avsforum.com/avs-vb/showthread.php?t=754996 for an entire thread documenting at least 30 of these.
When I contacted customer service, the rep denied any knowledge of such a defect, and said they would charge $375 to repair my $500 television. He then cold-transferred my call to the voicemail of someone named Patricia at this company. Since then, when I call their customer service number, the phone will ring but no one will answer.
