Re: samsung ue55nu7021k backlights working but blank screen
So the board arrived this morning! I replaced the old one and the TV is back up and working!
Thank you both for your help on this, I had assumed my TV couldn't be repaired! Its fairly simple as well, as long as you get the right parts.
Can I ask if it's possible to determine whats wrong with the old one, can you test the various components in some way?

Re: samsung ue55nu7021k backlights working but blank screen
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?...

Re: samsung ue55nu7021k backlights working but blank screen
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?...

Re: samsung ue55nu7021k backlights working but blank screen
Hi all, just looking at that board I found. It has several numbers on it. The first number matches the sticker on the one within the tv on the green board (BN94-12869M) but the others on the product description do not?
It lists BN41-02662A BN40-00330B EL8240 WX2A, I can't find these on my TV. Is that a problem or is this the right one for my TV?
I know its a risk but for £45, I might as well give it a go.

Re: samsung ue55nu7021k backlights working but blank screen
OK great advice here, thank you all. So if this is the right one might as well chance it and see if this solves my problem. Its £40 but prob worth the chance! This is definately the right one for my TV right?
Also, is it easy to change these over?...

Re: samsung ue55nu7021k backlights working but blank screen
That's interesting as I had been trying to connect the TV to my modem via a hardwired connection as opposed to connect via wireless and I would have connected my firestick to the TV while it's plugged in! So maybe that's what's caused the issue....

Re: samsung ue55nu7021k backlights working but blank screen
So just checked this once again and managed to get the fire stick on the HDMI port displaying. Although the round circle suggesting its thinking keep constantly coming as well as the message as per the photos. I've also uploaded a video (zip file) to show how its constantly cycling between the screen, then get the thinking circle and then the message after-which your back to the display from the input....

Re: samsung ue55nu7021k backlights working but blank screen
So on odd occasions I could get inputs to works, could only switch via the buttons on the tv itself but whilst i got picture, got no sound.
Sorry can I ask what you mean connected too HOT?...Last edited by Yoda79; 12-18-2021, 09:42 AM.
