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 3 years ago.

Over the last several weeks ith has gotten worse

Yes it seems to work better when warm.

Expert:  Jack replied 3 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 ?
Customer: replied 3 years ago.
Yes I would like to look into to it myself
Expert:  Jack replied 3 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 3 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 3 years ago.
No problem, just send me a reply and i`ll be with you ASAP.
Also if you could lookup that model number again as a reply?
Customer: replied 3 years ago.

Customer: replied 3 years ago.

Expert:  Jack replied 3 years ago.

Hello, once you have the back cover removed,look for the circuit below, then we`ll take it from there.
