Compatibility/Interchangeability:
-
Compatible with 65UM7300PUA/BUS, and likely other 65UM7xxx models (e.g., 65UM7290PTO)
-
Boards from similar models may work, but firmware may identify the wrong TV model and require serial number transfer via a service remote.
-
Most community swaps (e.g., EAX68253604 working on 65UM6950, etc.) have been plug‑and‑play, though firmware details may show incorrectly
🔧 If your board is faulty:
-
Replacement boards (new or used) are available online under part numbers EBT65772802, EAX68253604/05.
-
Expect to factory-reset and reboot after installation.
-
For new boards, you may need to use a service remote or LG’s companion tool to transfer key settings (serial number, DRM data) to enable streaming apps
-
Many users have successfully swapped used boards without issues and simply performed a reset .
