Hi all, This is a post on behalf of my parents who have gone irate that their Sony Tv has seemingly stopped working. This is what happened. Whilst watching the TV the TV turned off as if it went into standby mode. You can then try and press a button to turn it on, it will briefly turn on but then go off again. Whilst in this standby mode the standby L.E.D will flash 4 times pause and then 4 times again. The reason I ask whether the tube has blown is because I had a Sony TV that also did something similar to me a while back. Their tv is only 2 years old so out of warrenty. Any ideas? Has the tube blown? Thanks. Dave.
