Purchased mine used last May but only used it for like 10 hours total till around mid november then afterwards used it as my main tv until mid june when I moved to a flat and now using a old CRT so its only ever used for my 360 or PS3 or hd content for internet.
Just worried that the times I have used it it can be on 8-12 hours a day would be a lot
Its a business model too, have seen it in many bars like Wetherspoons (a Panasonic one)
I assume they last a few years general use? I am hoping 3 years minimum and ideally about 5 years.
