Hi All,
Here we have a UHD TV with integrated TCON. The motherboard BN41-02568B failed, I could not get exactly the same but another BN41-02568B from a 6 series with a different sized screen.
Backlight and sound are fine, but no voltages on the buffer board except 3V3 and no AVDD on the motherboard, either with or without the panel ribbon cables attached. The MOSFET feeding AVDD (Q400_UT, DMG4435SSS) is getting 12V at its Source terminal.
AVDD is at high impedance to ground in off condition.
I don't know where the other voltages for the buffer/panel are supposed to come from - MB or buffer board.
Is there a link I need to check which tells the MB whether the panel has a separate TCON or not?
Thank you!
