Then, what I read in another post , I bought an ethernet Arduino ( Arduino mega + shield ethernet) , but I could not read what he has my eeprom ( do not know why ) , and that was my last attempt. I would be grateful if I can lead. Many thanks.
These are some of the post I have guided:

Try searching the forum for the word "MiCOM" ...
You will find several threads ..
All threads end up the same way ... If you upgrade MiCOM, you killed the motherboard basically.
Only known fix is to buy new motherboard ...
In the references mentioned I indicate this post, I just do not quite understand if the VGA connection with my eXLink. And I dont have the .bin whit my chipzoelechat wrote:A guy posted some possible clue a few days ago: https://forum.samygo.tv/viewtopic.php?f ... 791#p86791
Were you able to find a solution to this problem. Please let me know how you were able to reverse the MICOM updrade accident. I have done the same thing. I went into service menu and before I knew it I had selected the MICOM Upgrade by accident and it locked up my TV. I unplugged the TV and now it will not turn on at all. The standby light is off, does not illuminate. Could really use some help. Thanks in advance.
BTW, I have a Samsung UN46EH5300F.
What really you need is programmer and use method, described on that referenced topic. I even think you can use micom firmware from there as attached programming file (ue40eh5000w_wt61p805_388.rar) fits for your TV well IMO.
If you know someone with RT809 or any other programmers with possibility to program via VGA ISP (usually this is how masters repair bricked LCD monitors), then you could try. Or ask in your repair service.
Optional you can buy one for you (e.g. https://www.ebay.com/itm/New-RT809F-USB ... 321?_ul=AR) and do everything for yourself. But i`m not responsible about result, it might not work on your TV, this is also possible...
