I have a Phillips dream station 2 cpap that quit working. I can see a burn mark on the circuit board. I cleaned everything up but it’s still not working. There are no service parts available.
I can’t sleep without it and it may be a few weeks before I can get a new machine. Is it possible to repair this board and what would I need?
The cpap turns on fine and goes to the main menu correctly. However,when pressing the button to start the “air” blowing its like it gets stuck in a boot loop and does this about 3 times then gives me an error message. Any help would be greatly appreciated!

it looks to have liquid damage. I dont think anyone will be able to guide you through any time of repair with it if you have no experience with that type of work.

I have some. I am assuming that transistor needs replaced. How would I go about finding a proper replacement with no markings on it.

q3?
looks like it would be same as q2 & q3 to me. All 3 are same layout.

It has a ton of liquid damage though. Many of the smd components are going to be heavily oxidized. Q3 is the least of your problems.
