Perfectly happy with my purchase until ... I plug! Upon connecting, even need to turn it on, it starts whistling for 10 minutes, the same as when turned off. Two days after purchase, I contacted the SAV SONY who reacted perfectly smoothly. A technician came to my home to change the power board of the TV (free of course), and since it is HAPPINESS (known issue that Sony has also just released a new map of power supply for this TV model) . A buy eyes closed, anyway SAV Sony is there;)
