Nope. From the conversations I remember on here months ago, there was some
lengthy debate as to whether the whole concept of reforming caps was a
farce and that trying to do so was, perhaps, more dangerous than just
turning the thing on. I tried to look at archives for details on how to do
it, but it seems they're not up currently.
On that note, maybe this is good fodder for the wiki discussion that was
going on last week. If I could've made a more informed decision and
possibly saved my rare machine by having that information readily
accessible, that would've been a good thing.
So anyway, I found a really nice manual online for the tek. I'm too much
of an amateur to just dig in and start analysing it myself. Anyone have
suggestions on what to look for and where to start? Should I put together
a simple PC parallel port logic analyser?
thx

caps checked and formed before turning on? don't

Hi,
I pulled my tek4015-1 from storage (~10 years, dry but cold, had been
working perfectly then) and brought it home to my living room, much to the
dismay of my significant other. I plugged it in. it squealed a bit,
zapped a little and lit up with that signature green expanding circle. I
was able to get the line/local light to behave reasonably and it seemed to
go into local mode ok. Was hoping to echo characters to the screen, but
no
love.
The screen is really bright. It's as if the whole thing was in the
lit-up state. PAGE key does blink the screen, but I remember it flashing
brightly whilst erasing in the past. Now it looks like it's just staying
bright all the time. I wiggled the boards in the cage around and managed
to get it to repeat control-g feeps (while holding those keys down), but
it's only able to do it intermittently, seems related to the positioning
(or complete absence) of the display driver board. Still no characters
showing up.
Does anyone know how to work on these?
thx
jake
