Re: the contrast, the 1000
series modules have a provision for contrast adjustment.? Just add
a pot (2K to 50K, the value isn't critical) in the R005 location,
and cut the circuit trace between the center pin of R005 and the
pin toward the front of the unit.? A Bourns or Beckman 3/8"
multi-turn pot will work fine.

Brian

Thanks, Larry.
There was an error on my previous post. There IS a
connector on the K1000 display; you have to desolder it and
solder on the brand new display, instead of desoldering wires.
It was my mistake, because I had to do that on an Akai
AR900 which uses the same type of display, but with better
results on the AR900 when talking about contrast.

Hello all,
And here it is the result. The ultracheap display
works on the K1000 modules series.
It is not an impossible task, but for a very few cost
you can get an acceptable -not perfect- result.
Most important thing is about contrast, that I solved
by placing the module on the lower side of the rack,
so I can read perfectly the displayed characters.?
LED backlight is very good, too much light for a dark
environment, but it won?t burn your eyes.
Second is about LCD module placement into the chassis:
you have to make some brico tricks to place it on the
right place. Original display is a lot much thinner.
And finally you will need soldering skills to desolder
the display wires (14 iirc) and resolder them on the
new display. No connectors, etc....
