Hello it seems somehow my s300 and my ecu got damaged a component on q34 on a p72 ecu is fried. Also the s300 will not light up or anything when placed into a good working ecu I am posting the pictures in hope someone can shed some insight on how screwed I am or if the s300 can be repaired.

Physically it looks just fine, no burns anywhere on it but I just wanted to ask ive done electronics repair before but usually there are physical signs of damage. This time is nothing.

Anyways I added the pics showing the damage to the ecu and pictures of the s300, hopefully someone can chime in.

Thanks
