    Vivax 32'' MSD309.8B no picture

    Hi guys,
    I have 32'' Vivax TV set that is stuck on red standby, wont turn on, backlight doesn't flash, tried torch test but no luck. I can feel the mainboard chip getting warm, and also the chip on PL.MS6M30.1b is getting warm.
    All voltages from PSU are okay, 12V, 5V, 5Vstby, etc, also there is also voltage on LVDS cable, 1.3V-1.4V.
    Question i have is, on the input to T-Con there is LVDS voltage on "data wires" but there is no 5V or 12V for panel to turn on, also on Inverter board voltage coming from PSU is 24V which seem alright. Status pin on inv board is 0V, VBR-B is 4.7V, ON/OFF is 0V.

    MS6M30.1B

    You have corrupt firmware on the motherboard epprom/flash chip. Replace the mb or find a replacement epprom with correct firmware.

          Btw guys, one general question about LVDS and LCD panels. For LCD panel to work does it need a power supply except the LVDS 1.2 1-3V voltages that are given by T-Con. Ofcourse we are not talking about backlight voltages needed for backlight to operate...
          Any good videos to watch or books to read for recomend?
