    je voudrais mettre cette carte sur mon téléviseurToshiba (48L5435), mais je n'arrive pas à mettre le firmware Toshiba sur cette carte "Medion"
    d'abord, cela est-il possible d'après-vous ?

    mes essais:
    format USB: FAT/FAT32
    firmware Medion/firmware Toshiba
    j'arrive à déclencher la mise à jour en tapant Menu->1505, mais ça me marque à chaque fois: "Software update failed"

    le firmware que j'ai trouvé pour mon Toshiba ne contient qu'un fichier (spi-vistel-17mb95m-48l5435dg-.bin); est-ce normal ?
    j'ai essayé le votre (les 3 fichiers) pour voir, et j'ai toujours marqué Failed

    merci par avance de vos réponses !

    "spi-vistel-17mb95m-48l5435dg-.bin" is the firmware (dump) through the programmer for spi flash MX25L1606E.​

    Hello everyone,

    I just got a 17MB95M card from a Medion TV (MD30814)
    I would like to put this card on my Toshiba television (48L5435), but I cannot put the Toshiba firmware on this "Medion" card
    first of all, do you think this is possible?

    my tests:
    USB format: FAT/FAT32
    Medion firmware/Toshiba firmware
    I manage to trigger the update by typing Menu->1505, but it gets me every time: "Software update failed"

    the firmware I found for my Toshiba only contains one file (spi-vistel-17mb95m-48l5435dg-.bin); is this normal?
    I tried yours (the 3 files) to see, and I always marked Failed

    Thank you in advance for your answers!
    Christian​

    and where to get a new DC-DC?

    This is the dc-dc converter that I think is faulty. After it is detached, measure between VGL and VGH. If it is shorter it means that the fault is in the panel.

    which tools would I need, I got a hot air gun somewhere and to be honest, can't make it any worse anyway Let me take some close up pictures first.


    There we go:

    This means that the integrated dc-dc converter is defective. If you can take a close up picture I'll tell you what it is. But I don't think you have the tools to replace it. The t-cone being glued to the panel does not pose the problem of its replacement.

    VGH and VGL are both about 740 Ohm against Ground. If I bell it through VGH against VGL it seems to be connected.

    Wait a second. Just checked it with a magnifier. I measured VCH instead of VGH. The only one I found on the board sort of similiar to what you said is VGHP and has a value of 48 kOhm.

    Just to clarify:
    So, VCH and VGL are connected with each of them 740 Ohm against ground. VGHP has 48 kOhm,

    Rails: vgh, vgl, 12v, 5v, 24v etc.
    What resistance do you find on VGH?
    The VGH measurement point starts from the integrated one.

    I have belled through all available SMD parts against ground and almost all of them seem to be sound. Where can I check the DCDC converter?

    What rails do you mean exactly?

    That's not good. VGH is positive voltage and can exceed + 20V. VGL is negative voltage and is around -6V. There is a dc-dc converter that generates these voltages. If it is burned it can be replaced. Or it may be a short in the panel. Or a short on one of the 2 rails (smd capacitor in short, diode, etc.). Measure the resistance on them against the ground.

    2.2mV on both, assuming I have found the right one. Pretty sure to have measured VGL, not sure if VGH was the correct one though.

    T-con is part of the panel. Near the connector is a fuse. See if it's good and you have 12v (or 5v) on both ends.
    11.3V it's showing.

    If you do not have an image it can be the problem in the t-con.
    Thought about the T-Con board though, but replaced the 17MB95M. Is there a specific T-Con Board for this model? Isn't that backlight controller with a fix connection to the LCD panel cable attached?

    There is no damage. The backlight tries to adjust brightness as well, so I see it going darker. No further reaction though
    Oh got the misunderstanding. No there is no image I can see unfortunately, tried with a super bright LED flashlight. When switching programs up and down the backlight becomes brighter and adjusts itself again back to black with less brightness.

    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...

    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?

    Firmware for older Toshiba TV 22CV100U
    by DarrenHD
    HI all, Does anyone know if there exists an archive for older firmwares for Toshiba TV's? I've searched all over Toshiba's various websites and also on Dynabook's site (they say they deleted all old firmwares due to "server space". ) Toshiba has not replied to my request.

    I'm looking for Firmware 1.07 for the 19/22/26/32 C100U series as described in this link:

    Thanks!
