This must be for a projector, finding anything on their computer/touch screen displays is near impossible. If anyone is reading this in 2019, I have two Infocus inf7021 units, neither work. I just acquired them recently and may start to work on them soon. I'd like to find a schematic (LOL) on them, but I don't see that happening, so I will have to work on them blindly. If by chance, I don't fix them, I will be selling them for parts. From what I can tell, the units have two power supplies, one main power supply much like one you would find in a flat panel television and another power supply that is similar to what you would find in a small form factor computer. I have yet to pull the smaller power supply out, but I did remove the main power supply, I do not see anything blown or any areas that have excessive heat, kinda strange, usually something on a board shows up as defective.

On the Dell power supplies there is a 22uF at 50 volt cap that causes them to die. Is there one of those on that power supply?

Joe Grech, Then do yourself. Then upload it so we can trash it. You're welcome.
