Welcome to the site. A good start is as I mentioned in your initial post was to provide good pictures and any voltage measurement you have taken so far. We do not have the set in front of us so the information requested would help.

Is there damage to this component?

Are you certain you have 35V at P5 (STBY5V_ON)

This looks like a bad PSU from what I've read so far. Do you want to repair the PSU or simply/easier replace the PSU?
