I wonder if anyone has the service manuals (or schematics) for the TSU9300 and TSU9400?

NB - I know this is a topic usually frowned upon as there are concerns about voiding warranty, etc. But I think that by now the majority of Pronto's are past their warranty anyway.

Unfortunately, my pile of backup TSUs is coming to an end, and I have a pile of TSU9400 and a TSU9300 that are dead (dropped, etc) and am looking to try to fix them. While a service manual is not critical - it helps a lot and can save time.

If concerned about safety - I do quite a bit of electronics work and own several test equipment like an Oscilloscope, a bench and 2 handheld DMMs, dual and triple power supplies, Metcal soldering station & hot air desoldering kit, etc.
