    I have already changed him a few SPI batch downloaded from this forum and unchanged. The TV has a main board CV9203H-A42 and a matrix CX315DLEDM with the designation of the plate with flexes VVH32H147G00-3. The sticker with the given tv model also has the code LED3204vELE00AF06171.
    The TV does not respond to the remote control and local keyboard, only the s-by diode as I described in the title automatically every 12 seconds. blink. Voltage on SPI correct and other on stabilizers also approx. Slightly warm. The SPI Winbond 25Q32 memory that was removed could be read, but it could not be deleted at all, so I uploaded new batches to a completely new bone. And I don't know if the main board is dead or if the SPI batch must be dedicated to this TV. I am asking for suggestions.

    Thanks gentlemen, both the file indicated by stacho57 and fox uploaded to SPI and made an attempt via USB - unfortunately no effect. I will try to return to the original memory, which did not want to be deleted, and give the above files via USB and we will see.

    It didn't work, unless you need to look for a new main board ??

    This is not the fault of any memory slam.
    The u2 converter or more precisely the adjacent 12v voltage is to be blamed.

    Maybe something will tell a friend more, what does this U2 converter mean ??

    U2 is a symbol described on the TV disc. This is how integrated circuits are marked.

    But you helped !!!!! A colleague of zebro wrote 789 posts and has been on the forum since 2005. You didn't notice it. Sorry. Try harder.

    Which U2 system is it? / * yellow arrow
    - it's some kind of stabilizer in ob. SOT25-? (3-pin or 5-pin), what's the power supply?, Description on the housing?

    Hello
    U2 on this board is WB6DV, six pins.

    I do not have such a description smd, under this arrangement. (Probably Chinese designation)
    You have to draw the layout on a piece of paper and then according to link

    Because it's next to the invert connector. or power supply?
    - then LED UB302 driver, .... / * there are topics on the forum

    And on this plate someone may know also U2 is responsible for the same symptoms?

Topic summary

The Manta LED3204 TV is experiencing a failure to start, indicated by a standby diode blinking every 12 seconds. The main board is identified as CV9203H-A42, and the matrix is CX315DLEDM. The user has attempted to upload various SPI firmware files without success and is uncertain whether the issue lies with the main board or the SPI firmware compatibility. Suggestions from the forum include checking the U2 voltage converter, which may be responsible for the symptoms, and verifying the voltage levels at various points on the board. The U2 component is identified as a six-pin WB6DV stabilizer. Further troubleshooting involves returning to the original memory and testing the voltages at specific points to diagnose the problem.
