BOARD BN41-02662A is the PCB number.

Great thanks for explaining that Lotas!

The number is not visible, and the matrix models are different.

This site is awesome! Irrespective of whether this works or not you have both been of great help.

Vince - on this one they don't quote the BN94-12869M number and you can't see from the picture on the advert. However as you say the BN41-02662A matches which is printed on the board as well as BN95-05414Q on the sticker on metal surround.

Lotas did say that the important one to match is the part number BN94-12869M corresponds?

This mainboard can also be installed, but you have to change the parameters in the servicing mode.
But it's better not to risk it.

Like yoda says thanks for explaining that lotas a lot of people like myself struggle knowing what numbers actually matter when trying to purchase replacement mainboards. maybe if you get time could you possibly please make a sticky thread on what numbers matter etc as a lot of members dont have programmers so prefer a board swap.

I managed to get the seller on ebay to send me the number on the sticker, this is slightly different, it shows a number of BN94-12869G. My existing one is BN94-12869M. Photo attached of the number from the ebay seller.

I'm guessing this would need to change the parameters in the servicing mode as you say? Or now knowing this, do you think this one would work?

I just read the whole thread and was wondering something? Why don't you just get the correct board from a Samsung authorised dealer who will 100% supply you with the correct board? Is it more expensive?

Re: samsung ue55nu7021k backlights working but blank screen

129.50 euros, ah yes almost half the price of a new tv. Sounds familiar. Yes these Samsung spares are pricey.

Re: samsung ue55nu7021k backlights working but blank screen

Its the Smart TV motherboards. They are all very expensive.

Yes, they will come up for replacement, they have a corresponding part number, but it is cheaper for her to have a bent connector.
On the first link, he also has a 30-day warranty.
