If you have a newer screwless Samsung Television, you can use our Jig tool to open it.
www.ebay.co.uk...
Using this Jig tool prevent to crack the plastic clips, bend the holding wire... Making possible to close back after the repair without any problem. We have updated this design in the last 4 years. One Jig tool can open around 10-30 television before braking up. We use the same in our shop.

Where from u purchase feeded nand because when we will try to read backup the programer will be cracked id & set could be gose in 3 blink the D series is very risky

We are bought empty chips, usually 10 at the same time. We saved the nand software from working television. When we don't find for a model, we usually download from BadCaps (find link below).
Many of the new nand chip is already has bad cells, so first we check all the chips. Usually a 50% is is returned.
Once we have a good chip, we write the dump using one of our programmers.
Many times you can see the same problem rebooting, but the problem is in 30% is a bad soldering.
I got better after 50 mainboard repair, but still making mistakes.
Sometimes the heat can also damage the chip, so if it is not working, sometimes a remove it and verify the firmware. If the chip is damaged, I just replace it.
If I find a good seller, I always order 5 extra chips just for stock.
