I purchased the screen from:
http://www.zinguy.com/lcdpage.htm
based on the description of replacing SY77 screen I found on the net - I
think on EX5 discussion board.
The description doesn't quite work for TG77 since the oscilator crystal
on the back of the screen is too high, so I needed to do some soldering
and than everything worked fine. Not reqlly a job for a soldering iron
beginer since you also need to find a source for +5V to supply the LED
with power.
However an avaradge electronics technician should be able to do a job in
under 45 minutes.
I used the same screen on Wavestation AD where the problem was different
- I think somebody mentioned limited space behind the screen on
Wavestation A/D.the solution is to use solderable 20 pin connector on
the ribbon cable. Again you need to find the right source for the +5V,
and in case you want the contrast control to work properly you need to
ad a 10K resistor to the top end of the contrast pot. This is not
necessary, and is not straightforward to do, but it protects the screen.
With K5000 it was similar. I still didn't have time to do the upgrade to
K5m, but it is next in line.
I wouldn't recommend you doing it if it is your first electronics
project. I would say Intermediate level and a professional soldering
iron fith fine tip are a requirement.

Dusan,
Would you mind telling which Screen (Part #) you used for your TG77
and which one for the Wavestation?
Was fitting them tricky? I have no experience of this kind of thing.
Sincerely,
Matthew (London)

ones
with the LED backlight, and I can note see the point of going through
all the trouble and messing about with the old technology backlights,
when the new screens do away with invertors and all the reliability
issues.
So far I have done the replacement on TG77, K5000R and Wavestation A/D
and will be doing the same with K5m.
You have to know what you are doing and be able to make the ribbon
cables with the right connectors but the result is great and lasts
much
longer than any of the old technology backlights.
On the subject of Wavestations A/D does anybody know what is the
latest
version of the OS and how can one get a hold of the EPROMS?
All the best,
Dusan

Yes, you need to buy your backlight from Telesis. I can attest to
the
greatness of the Telesis product. The screen for the AD is
exactly the
same as the keyboard versions. I own the AD and used to own the
EX. I
had to replace the backlight on that EX before I sold it and I bought
the backlight from Telesis. It worked marvelously! Too good really.
That screen was so bright it was almost unnatural. I think I paid
some
$40 total for it back in the summer. Maybe shipping is more
expensive
now I don't know, but I think the price should still be the same.
You need to know how to solder in order to install it and you have to
read those instructions VERY carefully, otherwise you can damage your
screen putting in the new light. It's not that difficult. Just a
tricky, delicate process. I can't solder so I got a friend to do it.
The screen is very easily accessible in the AD. There's almost
nothing
inside that box. I've opened mine before. All that space is really
taken up with just circuit boards resting on the bottom. It's
quite an
efficiently designed electronic machine, unlike the keyboard version
which is a whole nother story all together! That board's got several
layers of stuff to take out before you can get to the screen.
Probably
because it has an actual keyboard.
Telesis gives you a CD with the instructions on how to do it. It's
pretty clear and straight forward too. Just survey the scene and
don't
make any assumptions (like removing the old backlight, which you
DON'T
do!). Telesis also sells used gear too, and they have some great
prices
to boot! Perhaps I shouldn't give away the secret but I got a Roland
XV-5080 from them with 3 SR-JV cards expansion cards (orchestral,
techno
and that sampler SR-JV99 card Roland made) for $750! No joke. Check
out Telesis. I got nothing but praise for those guys.

I have the plug-in version and I think they're fantastic. My one
major
gripe
|
is they do not replicate the A/D's audio in, so you can't access
the WS
effects
that way. I had guitar synth patches that require this and I'd
hoped to
retire
my A/D but no can do.

As for the screen, didn't digikey have a good replacement?

Subject: [WS] Hello!
Hello Everyone
I am a long time WS experimenter. I'm glad there are people
continuing
to host a list like this- hats off to you!
I have a Wavestation AD and am pondering the VSTi version at
some point.
I've owned an EX and SR previously as well. I own a project
room here
in sunny Milwaukee Wisconsin, USA where I record music and am
branching
out into commercial work. I'm always interested in helping however
possible FWIW.
I do, unfortunately need to replace the LCD in my AD and am
searching
for the part currently. I bought an LED backlit LCD, but I
don't think
it's going to work due to the thickness and the AD's compact
nature. If
anyone has any info on who still sells these, I'd be very
grateful for
your insight. I want to use the AD on an upcoming session and
hope to
have it happy again very soon.
Thanks everyone and Cheers!
