Hi and thank you for using justanswer.I`m going to help you with your tv but first i will have a few questions;
Did this problem appear gradually over the last few days/weeks ?Once the tv is warmed up (1hour) can you turn it off and on at will/normally ?
Over the last several weeks ith has gotten worse
Yes it seems to work better when warm.
Good, then the first thing to do will be to remove the back cover.Also could you confirm that your model is LNT4671 ?Then i`ll be able to get some info specific to your model.
I have to leave for work shortly so I do not have time now to start taking it apart.
Can I resume when I have more time?
Hello, once you have the back cover removed,look for the circuit below, then we`ll take it from there.
