Schematics for the main board needed please. Sticker on board states BN94-07517A but the silkscreen says BN41-02157B. Cant find here or anywhere on the web.
Backlights work when main boards disconnected. When connected and power button switched, the relay on the PSU board turns on for one second then back off.
While relay is on, all voltage rails are present and steady (scoped) on main board.
I love a good logic puzzle but getting lost without any schematics.
No shorts on ANY capacitor main board.

All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

Gidday from Downunder,
Chasing the Schematics and also the board view for the HP Laptop board, model
according to the board markings that is read sideways against the the side frame to the graphics card or the DDR4 slot it says the following for the Model,
“MODEL:OPAK”
Then assuming the card was still inserted into the slot, releasing the card and removing it will reveal the full markings printed on the board (not the card),
“DAOPAKMB6FO REV:F”
Below in smaller print is a small logo of I think a backwards R with the letter U with the left stroke of the...
