Hi there, I have a Sony kdl55hx823, Where the TV will power on and cut out after 5-10 seconds. i have tried a power reset and still have the same problem. The TV will cut out and display 4 blinking lights then pause then it repeats. The TV has just fell out of warranty (grr). Anyone have any idea what this fault code could mean. I'm thinking it could be the LD board. I have also just noticed a dark area on the panel itself. This TV has really trumped me. Wanting to get a second opinion before i try and see if i can fix it. Many thanks. Any more info needed just ask!
