Before checking this defect, I need to open the tv (remove the back cover of the tv) but I do not know how to do it, I already removed all the screws of the back of the tv. Can a colleague guide me?

I'm thinking that this type of TV problem is updating the TV software according to a video I watched on the internet.


For this purpose what would be the method or technique to be used without having to open the TV? (update)

Hi, I managed to open the TV by removing the back cover of the TV. I have found that the tv default of the standby LED is always on is on the main board with the video chip burned.
I asked the seller for the main code board EAX66492605 (1.0) if the main board he has is the model 49LF5100, he told me that being code EAX6649605 would give to put on the tv. I made the purchase of the board and when I received it, I noticed that my board main had some components that are not on the board main , as shown in the attached image.

Main board that was purchased


purchased main board that is different from the original (missing some components). The question is: if I remove the components of the original and put in the one that is missing (card that was purchased) will it work? Should I also change the memory 25L8035E and the H27U2G8F20TR, is that correct?
