Query: nothing but problems...

I bought this television in December. The problems occurred in March. I made a request to have a repairman come and he basically replaced everything in the unit. The problem was the light engine. Now that the parts in my tv are brand new, I thought my problems were well behind me, but I was wrong. After it was fixed 2 days ago, more problems occurred. When i try to change the contrast, brightness, etc., the settings would reset once I turned off the tv. Also, sometimes the tv won't turn on, it would just make this weird buzzing noise. The picture is now worse than before.For all the new owners, please advise that you will be dissapointed once it turns into a dog like mine did. The tv may work great out of the box and you may be tempted to write a "5 star" review on here shortly after viewing the tv, but wait until 2 months approaches and I guarantee you will have Nothing But Problems. Write a review after 2 months and you will see what I mean.
