If you bought yourself a television nowadays and it was a good make and you only have it turned on in the evenings, how long would you expect it to last for? Our television is six and a half years old and as suddenly given up the ghost. Should we expect ot to last longer?
There have been a lot of advances in TVs since you bought that one , a new one now is just one very large intigrated circuit. When they go that is it no repair is possible.
