    Different main board model firmware updtae

    If I install a compatible main board in a TV, which firmware should I install?
    The original TV's main board's firmware or the replacement main board's firmware?
    Original main board is, BN94-03366G and the replacement is, BN94-03366K.

    I have a UN55B8000 TV and I have installed a UN55B7000 main board, which shows as a compatible board for my TV.
    I have upgraded the firmware, using a 8000 firmware.
    TV, still shows up as a 7000 model. The difference between them is the 120Hz and 240Hz(8000).
    Which Hz do I have now?
    Can I update the model number, to a 8000 model in the service menu?

      IF the set is now working fine--I would leave WELL alone!

      Messing with different F/W versions can be 'dangerous'....!

      I doubt there'll be an issue if the on-screen says 7000 and it says 8000 on the rear cover!

        I would check into the LCD panel part number for the 240Hz vs the 120Hz. if they are the same I wouldn't worry, if that are not the same then I would have some concerns.

          I have changed the model number and screen size in the service menu and the TV works.
          I'm not sure though at the Type in the Options, which one should I chose, there are like 4 types in 55" size. I have tried three of them and I haven't noticed a difference.
          The 7000 model is 120Hz and the 8000 is 240Hz. If I have changed in the service menu the model number and the screen, I may still have the 240Hz? How can I verify this?

            Sony xbr-65x900c main board issues?
            by jb_Bak
            Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

            Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
            Power Board Connector that goes to Main board
            CN6401
            Pin 01 NC
            Pin 02 NC
            Pin 03 "BL_ON": 0V
            Pin 04 "N/C"
            Pin 05 "STBY 3.3V": 3.5V
            Pin 06 "GND": N/C
            Pin 07 "AC_OFF"...

            (SOLVED) - ONN 100012588 No Power, Then Rebooting After Main Board Change

            Issue: No Power, Then Rebooting After Main Board Change

            Short answer: replace main board and power board
            Technical answer: replace main board and Q306 & Q307 on power board.

            Long answer:

            TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....

            Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
            by Tynan Dill
            I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

            Upon bringing it home and plugging it up, it showed a standby light.

            I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

            The screen seems to blackout and stay black, but with a flashlight I can see the display.

            With my Playstation 4 connected via HDMI, and running a game I can hear sound.

            Assuming...

            Samsung UN75RU8000FXZA bad main board?
            by Lee M.
            When plugged in it will click and cycle the BL on and off, no pic and does not respond to remote. When I disconnect the cable from the PS board to the main board and then plug it in the BL will come on and stay on. There are only two boards in this set, the LVDS cables from the panel driver boards connect directly to the main board. Since the BL comes on and stays on I'm thinking the PS board is ok and the problem is on the main board. Should I order another main board or do I need to do more testing? thanks, Lee
