During my last visit to my local B&O store I was offered a second-hand Beovision 3-32 (from - I think- 2003). The set was returned to the shop as faulty, the service told that it's working but nobody knows how long, as it had some sort of tube problem (I don't know the exact story). Anyway at the moment the set works, picture is perfect, but as of the possible fault they cant sell it for any bigger total. New tube is available for around 800 EUR.
I bought the set for 150 EUR (including a second hand Beo4), the set will arrive tomorrow. The reason of buying it was clearly the price, and as the set works for now, I am happy! (I have one moth money-back warranty in case it breaks.)
In general, what is the reputation of this model, how well the tubes hold, and how good in general this Tv is? What should I test first, and how to expand the life of the tube / how to estimate how long it works?
