Perhaps I can help you with this problem but first could you please send me a reply when you see this ?

Expert:  Jack replied 1 year ago.

Thanks , a few questions coming up ;

Expert:  Jack replied 1 year ago.

Is the screen just blank with some background light or completely dark like when the tv is off ?
If you are not sure then darken the room and turn the tv off and on again while you observe the screen .

Customer: replied 1 year ago.
i requested a phone call
Customer: replied 1 year ago.
completely dark
Expert:  Jack replied 1 year ago.

Give me a minute here , if you want a phone call then i will have to switch PC and note that the website ( not me ) charges extra for that call

Customer: replied 1 year ago.

Customer: replied 1 year ago.
no phone call
Expert:  Jack replied 1 year ago.

O.k then , in any case right now i may have to give you links and part numbers etc.

Customer: replied 1 year ago.
waiting
Expert:  Jack replied 1 year ago.

Do you happen to have a flashlight handy ?

I would have a test for you.

Expert:  Jack replied 1 year ago.

Is the tv acting up right now ?

Customer: replied 1 year ago.
Expert:  Jack replied 1 year ago.

O.k then with the tv on (sound and all) turn on the flashlight and press it against the screen then while moving it around , look around the edges of the flashlight and into the screen to see if there is some picture in there ?
Note that it may be difficult to see and a dark room may make it easier .
Let me know what you see.

Customer: replied 1 year ago.
no tv off, in another part of the house
Expert:  Jack replied 1 year ago.

Tv off in another part of the house ??

Lets try this again ;

1 . Do you have a flashlight ?

2. is the tv acting up right now ?

Expert:  Jack replied 1 year ago.

If the tv is not acting up since it is off then when it does and if you do have a flashlight , try the test i described above

Expert:  Jack replied 1 year ago.

Right now it looks like your tv`s backlighting is acting up if you lose only the picture and still have the sound and also is completely dark " no background light " at all

Customer: replied 1 year ago.
ok i see a picture when it is black
Expert:  Jack replied 1 year ago.

O.k then that confirms it .

Now about your model number , could you look it up again please ?

Expert:  Jack replied 1 year ago.

Could it be NS-42 .........

Customer: replied 1 year ago.
NS-43D420NA16 REV B
Expert:  Jack replied 1 year ago.

Or perhaps NS-48D420NA16 REV B

NS-43 does not exist so it will be 48

Customer: replied 1 year ago.
looking again
Expert:  Jack replied 1 year ago.

This tv was made last year !

How long since you bought it ??

Expert:  Jack replied 1 year ago.

I know you bought it at bestbuy because they are made for them but how long have you had it now ?

Customer: replied 1 year ago.
its a NA 43 i buy sat
Customer: replied 1 year ago.
dish hook it up yesterday
Expert:  Jack replied 1 year ago.

You bought it Saturday ?

From best buy ?

Expert:  Jack replied 1 year ago.

O.k then this tv is defective , this has nothing to do with programming or connections if the screen goes off while ther is still picture in the background

Have them replace or refund this tv , you do not want the geek squad attempting repair on it .

In any case they probably will want to verify for themselves so even if you have to take it back yourself , ask for the exchange or refund that you are entitled to , not a repair .
