I have a N5767A, when power on the supply, it will appear "O7P" error, the user's guide said it caused the Over Temperature Protection, could you tell me the principle and the example circuit? Thanks!

Unless significant electrical damaged has occurred to the N5767A, "07P" errors which present shortly after turn-on (ac power), are predominately the result of some sort of fan related issue.

Anything which might decrease the RPM of ANY of the three (3) fans; dirt, defective, worn bearing, intermittent connection, etc. will cause the N5767A to report "07P" and shut-down.

Thanks Peter, I have checked the 3 fans, 2 of them have bad. It should haven't detected the fans and couldn't controlled the fan's RPM.
