I'm reviving a Duo 230. I've recapped it, replaced some bad diodes & the LT1171 voltage regulator (per a discussion in this forum that seems to have gotten lost in the crash last year).
The display is fine because it works with another working Duo I have.
It chimes, now that it's recapped & the new LT1171 didn't make it worse, but it goes straight to the pink lines after the chime.
I have a new LT1271 as well that I haven't replaced yet. Is this the next step? Finding more bad diodes perhaps? Replacing the LT1171 was a lot of work, given my current soldering skills, so I want to make sure that replacing LT1271 is worth the effort before I screw it up entirely.
