I bought a 42" LG plasma 3 weeks ago from Currys, and took it home. Immediately from installation, there was a loud / high pitch buzzing from the set. I gave it a couple of days to see if it was something that needed to "settle in", no change. I had taken out the "whatever happens" insurance so I gave them a call. An engineer came out to have a look. First thing he said was "I can see the problem as I walked up your drive, the contrast is set too high, that will be causing the buzzing noise!" We checked the settings, they were on the factory default settings - 80% "oh yes, thats the problem, its making the tv work too hard!" We changed the settings, no change!. Now come on, if the tv has a range of settings, all of those available settings should work satisfactorily? Anyway, this did not change the buzzing. He tried a few other things, no change. He put his head right behind the tv and said "all TV's buzz, thats just the power supply unit". This I can appreciate, but hearing the buzz when sitting 12feet away cannot be a normal noise. He then sat down by the TV, approx 2 feet away, and stated that he could not hear the noise, said it was working within spec and that there was nothing he could do about it, I would have to take it up with the shop! It is not just me who hears this noise, my GF and several others have also commented on it. So, I go back to the shop. They ring up mastercare and explain the problem, mastercare said" we have sent an engineer and they reported no fault. There is no fault with the TV!" I told the manager that this is not acceptable, he arranged for a guy from the store to come out and have a listen. He came yesterday, and he agreed with me that it was a noise which should not be there!!!!!! I get a call a little later to say that if I go into the store, they will replace the TV with another model of my choice!. But, if I get a buzzing noise again, I will have to live with it. I am partly happy with the outcome, however, if the other one develops a buzz, what do I do? Frankly, I just want a refund and want to buy another conventional CRT TV. I have most if not all of the packing boxes etc. How do I stand with this??? Thanks in advance...
