datasheet and information about 6c17504 and 1d17409 8pin ic

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?!

Please share the images.

Also what you have done to find out the problem or cause?
