I have used this TV for only around 15 Months Spend around £650/- and it stopped working. I tried to change the Power Board on the TV and also made sure that my Adapter is working fine. But no luck it is still not working. When I checked with your Authorized Service Center, They are saying they gave an estimate of around £300/- to fix this. I am really not happy the way this has gone through. Spending £650- I think I have received a Product that is has not served by purpose. I suspect the issue is with the main board. I was thinking that Sony is the best brand in the World that provides the best Product and Support possible. But unfortunately I was wrong. Instead of going with Sony, if I would have bought a cheaper product, then I would not have felt so bad. Please let me know whether Sony can help me fix this or let me know whether I have to put that in bin. Spending £300/- to fix the product is really not worthy.
