MainBoard for LE46C650

Dear friends,
I´ve found this forum after several days searching for a main board for my tv.
I found several boards, but all the stores as "0" in stock.
The Board references are:
  • BN41-01443A
  • BN94-02625V
For what I read, other boards can be fitted on my tv, but this is true?
In true, were can I find a list of compatible boards?
I have been told, that if I put other board, I need to flash it, is true? If true, this process is easy?
I´m tired of searching board on eBay and in web with no success.
Searching for the board for this particular TV, is almost impossible to find.
I found one on I B Electronics, but after several days I was refunded because they didn´t find the board.
I will upload some pictures of my board.
I´m from Portugal, but my TV was bought on the UK, so a board with other tuner can be applied too, because here the channels are in MPEG4, and this board as MPEG2 (I think).
So can you guys help me with this situation?

I suggest you go to local repair service and ask them to order new or second hand mainboard. Quite old model, has been already discontinued for few years. You can also ask here, but do not expect much.

Thank You for your suggestion.
The problem is that I sent a lot of emails to Samsung repair centers and I received only 1 answer, but the price was very hight.
I had the idea that this board wold be changed to other compatible board. Is so difficult to find this board.
Bit I will send a email to the site you mentioned, we never know...
Once again thank you for your suggestion.

I bought a replacement board, and now the TV still doesn't works.
The board I bought as the same reference, but the BN number is different.
The new board is the BN94-03454M. This board 03454, is also used in the same TV model, LE46C650.
The stand by ligth turns on, I turn on the TV, the Samsung sound plays, but no image, no ligth... Nothing happens, but the TV is On, however is impossible to know.
I turn off the TV and the shutdown sound plays and the stand by ligth apears as normal.
Can anybody help me understanding what is the problem?
I let a little vídeo with what it happens. But i don't know why, the sound is not possible to listen in the vídeo. https://youtu.be/gy-u4_cjnAw

If here is not the correct place to this doubt, please tell me were can I post it.

Regards

Thank you.
Its what I did, I followed this article:
https://wiki.samygo.tv/index.php?title= ... m_is_C.jpg.
However Unfortunately, it didn't work.
The Tv turns on (the sound plays), but the screen is Black, the ilumination doesn't turns on.
It seams the power doesn't arrive to the ilumination.
Any other idea? Thanks
