Thank you for your response Ian.
I have tried what you say, but no results. So I have made other tests, and I think I have found the solution but to confirm this, I must make other tests.
I have made a backup of all the EPG folder in ‘ProgramData\Microsoft\Ehome
After that, I have made a reset of my TV configuration in MCE, closed the MCE, and I have killed all the Eh* processes.
After that, I have deleted the EPG folder, and replace with my backup and started again the MCE. All the parameters of the TV was restored..
This result means that all the TV settings (Channels order and channels frequency without scan). So, I think it’s good, but to be sure, I must make other tests.
