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 ?

Customer: replied 6 years ago.

Over the last several weeks ith has gotten worse

Yes it seems to work better when warm.

Expert:  Jack replied 6 years ago.
O.k then there is a very good chance that your power supply circuit is defective or starting to be and getting worse.

Would you like to look into this yourself ?

Yes I would like to look into to it myself
Expert:  Jack replied 6 years ago.

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.

Customer: replied 6 years ago.

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?


Expert:  Jack replied 6 years ago.
