I did some rough calcs and I estimate my TP32 has at least 1,000 hrs on the clock, often working its guts out in rough coastal work. Quartering swells are hard on a boat
which has a dwl of only 20 feet but with a w/l beam of almost 9 feet. Very hard to go in a straight line !! But the TP 32 is priceless compared to the first two Autohelm
2000's both of which had multiple weaknesses, especially drinking rain water
and drive belt stripping. I rebuilt both of those things twice before I realised that the TP 32 was REALLY cheaper in the first place. ( bit like buying
oats that have been through a horse already). In OZ we pay USD $900 for TP 32's so American buyers are getting great value.
As described by others, doing a factory reset and then a commissioning should be all thats necessary.
I really do doubt that you have a dry pcb joint.
I think you'll be fine if you follow the instruction book ( which really does need a sharp brain....mine often isn't.
If TP 32's doubled in price
........still good kit IMHO.
