I bought a Sony KDL-50W829b 50 inch 3D smart tv only 3 years ago (just) and recently I’ve lost the picture (sound and backlight working but a black screen). I took it to my local Sony Centre who told me that the ‘panel’ has gone (broken) and that they are unable to fix it as Sony no longer stock the panels and I might as well bin it!! I spent just under £1000 for the TV on it’s own, then £300 on the Sony 3D blue ray player, £100 on the 3D glasses and  another £300 On the 3D wireless Bluetooth sound bar and speaker to match!! To say I’m unhappy is an understatement! It’s bad enough that with most Sony TVs nowadays you are getting 5 years warranty as standard (my only had a year when bought it) and mine is outside the time but Sony have stopped supplying parts for a TV which is only 3 years old!!! I never thought my TV was useless after only 3 years...it’s a shame as the reason I bought a Sony in the first place was for the quality!!!
