hi , i have a power supply of epson eb-x41 projector that doesn't turn on . i haven't found the problem yet but in the power supply circuit it has 2 ics that i couldn't find any datasheet or just a little data about them, i think they should be switching ics but it's so strange for me why there is no data about them?!

Nothing strange about it, they might be in-house numbers, so no datasheets as it's a private number within Epson. In-house numbers have been common for decades, I first came across them in the late 60's.

then do you think i can provide them from the market and are they available for sell? or they are just for internal and in-house use?
