Yesterday evening one of my 170’s decided to stop functioning. It stopped and it wouldn’t response to powering it up. No charging after pressing stop, so I thought it was the belt although it is relatively new. I dismantled it and saw that the belt was still in good condition.
After reassembling still nothing.
Just as an experiment I replaced the main board with an old board from a 175… and it powered on!
Replaced the lid hinge and put it together with the silver top and bottom from the 175 and all is well!
But… did I just create a Frankenstein 175? And will it function like a 175 provided with the cable? I have no way of testing this.

We have done this multiple times. 170-175 and vice versa. It works.
The only difference is that board (besides cosmetic).

Yes, I’ve done that too and got two non-working 175’s to work. Unfortunately I messed up when I put things back together again: I replaced the fuse of one of them and while I did that, a tiny ball of solder tin ended up shorting a transistor so although that 175 still kind of works, it always goes into rewind when I power it up.
The PC cable still works too.

I guess some strong words after you discovered that than @Jac !
Obviously I’m over the moon with the function restored. I played it all day today in service mode and it is all 000000000 when playing. And it is nice to have this old skeleton of a 175 giving live after 10 years!
But still… what went wrong with the bord all over sudden???
I think I will leave it for a couple of days and than replace it. Just to see if it springs to life again. I’ve seen it happen before…
Well after 5 years I do know that the capacitors are on the way out! Do replace them before they damage the head! After that it is all lost!
To everyone replace or let replace the capacitors in dcc170/175!
