So, I bought a faulty rebooting Samsung QN700A with the grand plan of repairing it.
The panel looks fine, there's some mild dancing lines horizontally crossing the screen ever so slightly different brightness compared to rest of the screen, doesn't bother in PC mode.
Then after around 5 minutes the TV goes off and on, the image disappears, backlights stays on for couple second and TV reboots back to the logo.
After then it happens almost constantly.
Steps I've taken so far are:
Buy a 8k certified cable from John Lewis.
Replace the one connect box and cable.
Add heatsinks and replace thermal paste on motherboard.
Replace the motherboard.
Point a fan on the back of the TV.
Reflowed the solder on the 4 connectors from motherboard to display driver boards.
None of these fixed the issue, only delayed the inevitable bootloop.
Samsung doesn’t they told it is back luck !!!
