S0 → S3 → S5 sequencing:

The supply works for 5 seconds, then shuts down. lae791p rev 20 schematic better

A superior Rev 20 schematic includes voltage readings taken from a working unit. You should see: S0 → S3 → S5 sequencing:

If the schematic you are using does not have these DC values printed, it is likely a factory schematic that expects an engineer to memorize them. For field repairs, you need the "annotated" version. The supply works for 5 seconds, then shuts down

A standard schematic found in a Service Manual is usually sufficient, but a "better" schematic for repair purposes includes the following proper features:

A concise, practical write-up of the LAE791P Rev 20 schematic: key blocks, signal flow, power rails, common components, likely functions, troubleshooting hints, and PCB-level considerations for debugging or modification.
