I have unlocked the bootloader to try some roms, but too late I understand that this will make the Bravia Engine to stop working... If I relock my bootloader will that make the Bravia Engine to work again?

Just relocking won't work, you need to restore the TA partition (which contains DRM keys for Bravia Engine) that you must have backed up before unlocking your bootloader.

@БориславМинчев: If you have a TA backup yes, if not no. – Shywim Feb 15 '14 at 12:21
