I re-capped the power supply about 2 years ago with high quality 105°
caps. I replaced *all* electrolytics on the PSU. With the fault showing,
the measured voltages are 24,07V; 16,92V; 7,78V; 5,10V; 3,30V and 2,30V.

If it's the same PSU the TF5800/5810 use, you appear to be missing 12v.
The 2.30v seems anomalous - that's where I'd start looking.

It has 3.3v, 5.0v, 8v, 12v, 17v, 22v, 30v, 15v.
