Need some help reading and understanding this electrical diagram

If you would go back to page 3 you will see the pictures that you requested earlier. (front and back of PC board) I can see them if you cannot see them let me know and I will post them again.

Sorry I did not see them. You can get the schematic of this one yourself if you like. It’s a single side board. And use whatever the manufacture sent you as a starting template and fill the data with the elements values. I did this years ago and it was not fun but it got me through. After you get the schematic done it will be easier for you as you can make a spare board if you ever need one. From what I can tell from the photo the only discoloration is near the diodes at the corner but you already found it. If you go and start replacing components without checking the rest will require a lot of components if something else was burned damaged. My bet is keep an eye on the capacitors.
