Help with hi12 "voltage regulator" burned out

Hi all.
I have a hi12 that I stopped turning on and sent it to repair. The technician has told me that he has burned two components of the board but you cannot see what exactly they are and we do not have the diagram to be able to verify it. The technician says that there are two “Voltage Regulators” someone who has this hi12 could help me if he could send me a detailed photo of those components. I’m going to upload a photo here to show you what they are. Let’s see if you can help me please.I will appreciate it very much. If I do not know what components they are, I will never get my h12 back and it has a short time of use but no guarantee.
I await your help please.
Thank you very much
