Hello,

I have a problem with this equipment, it is not operational, and see inside a burnt component, it has all the code burned, it can not be identified to replace it. I attach the photo, only notice x..78HFP. I am an electronic engineer and would like to solve this problem. Please help me identify it.
I appreciate your support.
Thanks in advance

Good afternoon Luis,

Please see below. Also note there may be other issues with different components even if this chip is replaced.

Hello, thank you very much for the contribution, if someone has the scheme of the power supply of this echo sounder since it is very possible that other components are found in bad conditions.
If someone has the scheme and shares it with me, it would be very useful
Thanks in advance

The circuit schematics we have are for internal use only, sorry.
