I have a Tx32pb50 which has been away for repair due to the buzzing problem. Well it came back and at first I noticed no difference , after a short while however I noticed that the buzzing now stops after the set warms up (say about 1hr) The question is this, do I get it replaced (I'm waiting for a replacement at the moment) and risk getting a set which will buzz all the time as it would not of had the modification which my one has or do I cut my losses and keep the current set which in every other way is fantastic WHAT DO I DO??????????............HELP !!!!!
