Which I did, maybe a year or two ago, and then probably a few months later, to no avail. And now that I have another look at the place, there's still a faint dribble of activity… it's weird. Is anyone able to log in there and speak to a mod?

Can't find anything about it, let alone the manual. Anyone able to shed any light on it? Or what module with an available manual might be similar enough to use the manual? Thanks :D

Dunno if the light is much brighter, but it sure makes a hell of a lot of difference that it's pointing at the edge of the light spreader instead of straight up… (obviously it doesn't blow out your eyes like in the pic)

So I was watching a Youtube vid about interesting digital watches, and there was this DB-520 clone so blatant I wondered whether the module would actually fit in a real DB-520 (I've got a dead one, and this one has EL and melody alarm). I gather it was a collaboration between a couple of companies, Fumi and Raised by Wolves, in like 2008 or something.

Searching just brought up a bunch of old articles about it, so I went into the search options to pick results from only the last year, and...

This thread is intended to be a resource for anyone seeking to repair or customise an LCD, covering polariser sourcing and replacement, and hopefully if we put our heads together we may be able to figure out what's required to reproduce the printed graphics which usually can't survive the replacement of the rear polariser.

More ambitiously, perhaps we can even pioneer the repair of screen bleed, probably requiring the milking of a large LCD panel to yield a couple of drops of the precious…

There was a bit of black tape over the chips, but not only did I take it off, I cleaned off the remaining adhesive, lol… Those four springs for the LEDs are a smaller diameter than the usual size, so I was lucky it only took me five minutes to find the one I dropped on the beige carpet! Only…

At first it was going to be question, singular, then I thought, hey – a collection of such questions and answers could be an interesting resource.

So, to kick it off – (speaking from the POV of someone only familiar with Casios) you know how with the advent of electroflourescent backlights, they went to a setup where instead of the current which powers the light running through the button contact, the button became just a trigger for a timer (although in some watches, holding the button…
