    Vestel firmware

    Hello once more,
    Having the usual hard time attempting to download firmware updates for vestel rubbish...This time for a Toshiba 22D1333B.
    I seem to notice that vestel make this virtually impossible,and this tv has the usual red/green flashing lamp.
    Do they purposely go out of their way to prevent engineers from downloading software for their own cock-ups?.the flash corruption levels are beyond a joke for their products,and was mortified to find out even Panasonic uses their rubbish now.
    we have Sharp,Toshiba,jvc,and other big name brands which is essentially supermarket cack.
    Wonder what else is around the corner...

      I've seen Spansion used on a lot, Winbond for smaller stuff.
      The problem is the flash memory wears out due to high temperatures and small process size. MLC NAND flash has a 3,000 cycle lifespan, if the TV is writing to the NAND a lot, it will fail.

          i wonder if you can get compatable FRAM chips.
          i know you can by 24' series compatable FRAM.

            Yes Tom, but we are talking about 12 month old vestels,it's unlikely any vestel would operate 3000 cycles of off/on etc...even samsungs and lg sets used daily from 2006/2007 do not seem to have the vestel issues.
            Just very poor design,i put it down to,and a tight lipped "we are keeping the 30 second flash update fix to ourselves" approach they seem to have...

              I hate them nightmares to repair and normally the customer wont pay alot if the tv isn't that old.

                Well when they pick it out of the Argos catalogue for £70 why would they!

                Would be interesting to attach a serial port emulator to the appropriate SCART pins - apparently there's a debug port on two pins.

                  Vestel Firmware - Toshiba 32W133DN
                  by anlu
                  Hello, i have an old Toshiba 32W1333DN (sorry, misspelled the headline) TV that had the standby led green/red flashing and no lightup problem, i repaired it by measure the led output as suspect led problem, i measured the LED:s one by one and found one bad led, i replaced the the led-straps and the TV works.

                  Now i need to update the software because the new rc "RM-L890" does not work and i think maybe it could be an firmware issue?, i have struggled to find it without any success because all of the links where invalid, i contacted Toshiba but they do not support this model...

                  Finlux 65-FUC-8060 firmware request (Vestel 17MB130S 23473048 VES650QNTS-2D-U11)
                  by piernov
                  Hi,
                  Got a Finlux 65-FUC-8060 TV that doesn't turn on, 5V standby present from PSU, 3.3V on mainboard present, button signal gets pulled low when pressed, but mainboard never sends signal to PSU to turn main rails on.
                  I suspect corrupt firmware but I haven't been able to find anything for this TV.
                  TV model: Finlux 65-FUC-8060
                  Mainboard: Vestel 17MB130S 23473048
                  Panel: VES650QNTS-2D-U11

                  At the very least looking for a firmware that can make it turn on to confirm the problem, and hopefully a firmware that's compatible with the panel.

                  by TheUser
                  Hello to everyone ,

                  This is my first post here, and i would like to share with you a small story in case you can help me.

                  Docker Type-C Gen 2 - Model 40AS. Was given to me by a friend for free ,but with the problem that you cannot use the video output ports.

                  All ports work , USB , Ethernet, Type C ... but HDMI + Display Port don't work

                  I searched on reddit and google for problem similar to that, and a LOT of people had fixed this problem by updating the firmware. So i tried , i searched and found 1.1.13 utility and 1.1.20 utility that can help...

                  Toshiba 49U7763DB (Mainboard: Vestel 17MB120) firmware issues after sporadic power cu
                  by cheeky2
                  I have this Toshiba 49U7763DB Tv which was suffering issues after various electrical power cuts, which happened in quick succession
                  Originally the TV was powering on and then very shortly powering off. I managed to get into the menu structure before powering off and carry out a first time installation of the TV. Which didn't make much difference. I have managed to factory reset (that didn't make any difference either).
                  The firmware inside the 17MB120 is corrupted and is causing some strange issues so my question is does anyone have any suitable firmware for this model?
