Hey everyone,
I have a QE85Q900R The Frame TV. The mainboard was defective and I installed exactly the same mainboard from a "donor" TV. Even the production date was the same day. The number on the mainboard is BN41-02679B. The only difference between the two boards is the fact that the "donor" board came from a 75" TV. To be precise: QE75Q900R. I really hope to find here a dump file for the "donor" mainboard.
Thanks in advance.
