transistors - What is this substance on board?



So I’m trying to fix my blu-ray player and there are two spots where this beige stuff is. Is this there intentionally, or is this the result of some malfunction?


Could someone please explain what it is and why it happened? Thanks Image of substance

Answer



It's intentional. It's glue (of some sort) to keep parts steady and not break from vibrations when shipping or handling the unit.
