Gents I'm having a frustrating time with my 58AX802B It started to turn on with the Panasonic name coming up, then instead of going to the home screen it just went dark. It did usually go to the home screen after turning it off and on for perhaps a dozen times. Now it simply goes to the black screen after displaying the Panasonic name premanently. No warranty left as it was bought from a Panasonic outlet. Any ideas welcome please. It was an excellent telly for my needs and I can't afford anything like it for a good while. I suppose some board is responsible and I'm happy to change it myself If I can work out which one it is...? Cheers.
