Hi I've just recently joined 'All About Circuits' and I'd like to put a question to 'YOU' about a large flat-screen TV ( Model; (Sony KDF E50 A11E that my sister gave me. She said it went faulty and I asked her to describe what happened. This is what she told me. 'It comes on for about 10 mins then goes off'. That's it. Then I checked to see if that's what was actually happening; and basically that's what happens. Of course I looked for other symptoms beyond 'coming on & going off'. This is what I found. Remember, I've 'No Signal' source for the TV as it's stored in a shed at the foot of the garden. 1. On activating the Stand-by button I noticed a little Green LED PULSING on the front-panel then several seconds later it becomes a STEADY Green LED. 2. In the top right-hand corner of the screen Channel No 40 appears 3. Trying to change the channel number via the remote-control failed despite several attempts to do so. 4. The same outcome occurred via the front-panel, programme buttons. 5.Nevertheless, the TV remained ON for about 10 minutes then went OFF. 6. I let 'things' cool down for a while then when back and tried again. This time the symptoms were : Front panel Green LED comes on then changes to a pulsing RED then back to GREEN again. It cycles from one Steady Green to two pulsing REDS repeatedly. Anyone had experience this kind of fault in this particular model of TV?
