Expert:  Jack replied 7 months ago.

If you turn the tv off and back on , do you get a brief flash of the screen ?

Customer: replied 7 months ago.
No, comes on like normal but faint picture
Expert:  Jack replied 7 months ago.

O.k then and are some part of the screen brighter than others or is this evenly dark ?

Customer: replied 7 months ago.
evenly faint all over
Expert:  Jack replied 7 months ago.

O.k then it would appear you have a defective LED driver board .

Did you have in mind to look into repairing this yourself or simply would like to have an idea of what is involved and the costs of repair ?

Expert:  Jack replied 7 months ago.

That board cost some $50 by the way and is easy to replace

Customer: replied 7 months ago.
I'm a dental technician, so I can probably do it myself
Expert:  Jack replied 7 months ago.

O.k then there are 2 versions of it , can you look near the TV's model number for the version number ?

Will look like UD03 , UF03 etc.

Customer: replied 7 months ago.
Is that the same as the power supply board
Expert:  Jack replied 7 months ago.

Thats correct it is the power supply/led driver board both in one

Customer: replied 7 months ago.
I have the back off is that number on the board?
Expert:  Jack replied 7 months ago.

There is a BN44-00667A and BN44-00497A

Yes it will be on the bar code sticker and within the string of numbers

Expert:  Jack replied 7 months ago.

It may also be printed directly on the board

Customer: replied 7 months ago.

Got replacement board in today installed it , TV came on but same thing picture very faint, sound fine
Expert:  Jack replied 7 months ago.

I`m surprised then it can only mean the backlighting strips ; http://www.shopjimmy.com/samsung-bn96-21487a-bn96-24147a-bn96-24148a-led-strips-12-strips-interface-board.htm

But this is not an easy job like replacing that power board , you can get an idea here , not your model but same job ;

You should be able to return that power board by the way

Expert:  Jack replied 7 months ago.

Are you still able to see the TV's own menu anyway ?

Have you tried and see if you can get any control over the backlight adjust as well as brightness and contrast ?

Customer: replied 7 months ago.
I can see tv menu faintly will try to adjust
Expert:  Jack replied 7 months ago.

see if it has any control , I doubt you will be able to bring back the picture to normal though

Customer: replied 7 months ago.
tried that took the brightness level up to 100 from 35 little difference though
Expert:  Jack replied 7 months ago.

There should also be a backlight control in that menu and that would be the one that has the most effect (if any)

Expert:  Jack replied 7 months ago.

I just checked and there is a backlight control in the picture menu

Customer: replied 7 months ago.
I went their and the max on the backlight is 20 and I can't adjust it anymore
Expert:  Jack replied 7 months ago.

But it does vary ?

Expert:  Jack replied 7 months ago.

Even slightly if you turn it up/down ?

Customer: replied 7 months ago.
When I adjusted it down it did get darker and I adjusted it all the way up which made it a little brighter but not normal
Expert:  Jack replied 7 months ago.

O.k then I just wanted to know if the main board had some control over the failed backlight system

Just to make sure this was not a main board fault.

In that case that leaves only those strips as culprit

Customer: replied 7 months ago.
where are the strips you are talking about?
Expert:  Jack replied 7 months ago.

Did yo look at that youtube video ?

Expert:  Jack replied 7 months ago.

As I said , not your tv but same thing

Customer: replied 7 months ago.
watch it kind of intense
Customer: replied 7 months ago.
what kind of cost for these strips
Customer: replied 7 months ago.
looks kinda hard
Expert:  Jack replied 7 months ago.

gave you a link above for those strips but you will have to verify the lcd panel number (at the back) with what is listed at that link , here it is again; http://www.shopjimmy.com/samsung-bn96-21487a-bn96-24147a-bn96-24148a-led-strips-12-strips-interface-board.htm
