[Solved] Replacing eMMC on SONY KD-49X8309C TV: Main Board 1-894-595-12

Hello repair friends

TV SONY model KD-49X8309C, main 1-894-595-12, eMMC H26M52103FMR

the original eMMC is damaged, XGECU T56 gives reading and verification errors.

I replaced the eMMC with the same model, H26M52103FMR. I don't have the original program for this model, I put my program for KD-55X8509C.
The motherboard starts with orange/green led, and initial Sony music, but no picture and backlight. How can I switch the motherboard to 49 inches without picture? Is it possible?
Or do I need to find the program that will work with this model?
Thank you for your help

with the right program, it works better.
The reprogramming of the new eMMC worked perfectly with a dump found.
Thanks repair friends
