Here you got some Info how to replace your LCD Display if the backlight gets dimm and dark.

You wont need to replace the old EL-Backlight foil anymore, if you take a modern display with LED Backlight.

The LCD Display Replacement instructions her works for Synthesizer KORG, Yamaha, Kurzweil, Kawai, Akai MPC.

The following models are tested:

Kurzweil K2000 Rack and KB Version

Kurzweil K2500 / K2600 may work too, not tested.

Yamaha SY99, SY77, TG 77

KORG Wavestation EX, AD, Wavestation Classic

KORG T Series

KORG i2,i3 01R/W and maybe the X-Models too

KAWAI K5000 all models

maybe K5 too

AKAI MPC 1000 and MPC 2500

In the linklist you will see what LCD types are needed.

It is recommend not to unsolder and re-use the old connector Kit, but to purchase new sets.

Here is a dealer on ebay with the perfect Connectors: JUST-HONEST

He will ship international, fast and very well packed.

The most interesting Parts are items 252147177192 and 262476223511

wich allow perfect clone of actual connection.

Here the basic instruction:

Note: (link to perfect Displays will follow)

Example pictore of LCD Screen with connection:

The LED Backlight is very long lasting and not much more expensive than simple EL-Foil replacement.

It needs 5 Volt DC Power for the LED-Backlight, which is common and hasslefree, some different displays need only 3,5 Volt and you have to add som resistors.

But here you can use e.g. 5Volts of Floppy Disk Power of your Synth and have no Problem with calculating resistors.

First Step: Please read all the information here and in the links on bottom, ist no bad idea to google for some newer info or videos
as linked here. Thean you will see what addition connectors and cable you will need for YOUR synth.

Please: avoid any electrical statics when touching the display

Disclaimer: Modding and soldering at your own risk, I can not be held responsible for any damage!
As you know: Unplug the device first – HIGH VOLTAGE inside!

Connection to synth:

Depending on time and soldering skills you may re-use your old connector cable from the old display,
but I recommend to purchase a new one. there are different types, with small head connectors or big ones you can plug in.

Which ones depends on how much space is behind the display, and as mentioned below on some models you need right angled connectors.

Please look carefully how your old connector cable is build.

See ordering example from ebay for IDC 20 Connectors and cables in the links( seller Just-Honest) below.

Attention!

When soldering IDC to Display on some synths you have to leave 21+22 pins open (see details in the links)!
21+22 are only anode and cathode (+/-) for the LED Backlight.
Some Synths , e.g. K5000 need to leave some pins in the middle unconnected. In that case you can easily
solder your custom socket with simple Pin Headers (from ebay , for example).

You also have on the other side of the display 2 soldering points named „A“ + „K“ to feed
the backlight with 5 Volt.

See example picture here: (above the new display, below the old)
http://www.tellun.com/wavestation/WS_old_and_new.jpg

WARNING!!!!!!
!!!!!!!DO NOT: DO NOT feed the LED backlight of the new display with the power for the EL-Light Foil of the old Display!!!!

This is high voltage(!), coming from a small transformator or „Inverter“ which converts low voltage (often 5Volts) to high power.

Its best to remove or deactivate this small transformator /inverter , but you can use the Voltage coming IN the transformator to feed the LED backlight of the new display
if this is 5 Volts DC.

Note: On some synths you can easy get + 5 Volts from the source that powers the Floppy Drive.

The transformator for the EL-Foil Power is now obsolete, and it often was the reason for that whining display noise.
The usual case you already have searched the internet for some replacement solution,
but here I will provide you with some links for information and How-to´s:

Need Connector with left-out pins?

Just search ebay for „IDC20 PCB“, or „Pin Header“ if you want to build your own socket.
Here some example:

Connection on your Synth is from the side?
Look after this in ebay „20 way right angled header connector“.

Or just choose „abgewinkelt“ from JUST-HONEST

Some links for installation of the display- if one isnt working or you find newer, please mail me in the comments – Thank you!

Note: There are also many links on Google and vids on youtube which show only the replacemet of the EL-Foil,
but you will change the whole display, BUT: Here you may find some usefull hints how to open and re-assembling your device.

It´s never a bad idea to take photos when disassembling, also easyier when looking for similar parts (theconnectors) on ebay.

You may need to reinstall your OS to format the new Display.
Please note: If screen is blank after installing new display, you may have to adjust the contrast of the screen. (Hold Shift and Move Jog wheel)

Please note: On some models the Display connector is coming from the side, so you will need to make a socket
with a 20 pin right angled pcb header connector, see pictures in the links or on ebay or google.

This one is especially for SY99, but most steps of the SY77 are identical, so you should read them too.

Yamaha RS7000 Tips Tricks Tutorial Guide

Posted on by

Last year I got a Yamaha RS7000  Music Production Studio with very weak knobs – some encoders and most of them are pots /potentiometers. The repair of the knobs of a Yamaha RS 7000 is a very difficult thing and hard work, you have to dis-assemble the whole machine from the bottom to the front, pulling the PCB´s carefully out and than de- and re- solder the pots or encoders.

By the way, finding knob replacements is very hard too, you have to do some deep web search to find equivalent replacemnt potentiometers and encoders.

One simple trick / tip to let your Yamah RS 7000 knobs live longer

How do the knobs / pots /potentiometers live longer?

There is one simple hint I could not find in the manual so far, maybe its very hidden.

You just have to hold [SHIFT] while turning a knob to move in values of +/-10

So you can just „fly“ through the values with warp speed, without turning too much.

The complete list of Yamaha RS7000 Tips Tricks Tutorial Guide

Big thanks for this very usefull list of hints and tricks go to Phil Clendennin, aka „The Bad Mister“. Phil is a Yamaha professional.

Bad Mister’s RS7000 Tips:

Shortcuts:

  • Press [SHIFT]+[Fx] (Function buttons 1-4) to activate the numeric keypad via Sub-mode buttons – the numbers flash meaning you can enter data via buttons, press [ENTER] or [DO] to execute;

  • [OCT DOWN]+[OCT UP] = return to normal octave;

  • [SHIFT]+[UTILITY] to see available sequencer/sampler memory.

  • [SHIFT]+[MASTER] to return Master Effects to their default settings

  •  Factory Reset: Hold [OCT DOWN]+[OCT UP]+[STORE] on power up

  • Autoload: Hold TRACK button 1…9, on power up to activate Autoloads 1-9. You create the auto loads by, literally, naming the file “autold1”, “autold2”, “autold3”, etc. Once executed the unit will automatically load the file every time, until you reprogram it to look elsewhere. Holding track 10 on power up will cancel any programmed auto load. You can also place an auto load file on a SCSI drive. This makes it easy to pick up where you left off if you ever have to stop mid-session. Simply create an Autoload file in a folder named for the project in question, power up and you are back where you left off.

  • Hold [SHIFT] while turning a knob to move in values of +/-10

  • Hold [TRACK SELECT]+[ALL] while changing a function to affect all tracks simultaneously

  • Hold [TRACK SELECT]+[1-8] while changing a function to affect the first 8 tracks

  • Hold [TRACK SELECT]+[9-16] while changing a function to affect tracks 9 through 16

  • Test Routine: [PATTERN]+[PATTERN CHAIN]+[UTILITY] on power up

  • Update Routine: [REC]+[STOP] on power up

Create your own custom drum kits with the Yamaha RS7000

RS7000 Custom Kits Tips:

You will naturally develop your own favorite drum sounds. The RS7000 will let you assemble and manage your own custom kits. Custom kits will be made from user samples and can be best assembled in a SAMPLE COMMON Program location. Individual samples that have been created in a Sample Local Program can be copied to a Sample Common program. The advantage is that Common programs can be accessed from all Patterns and Songs – not just the one they were sampled into. There are several ways in which you can get samples into a Sample Common Program: As mentioned they can be copied. Sample locations are number 001 through 128 and C001 through C128, where C is Common. Samples can also be imported directly into Sample Common programs (if you select the location in the mixer prior to importing). Even samples that have been Sliced into segments can individually be copied to a location within a Common Program Kit. The Sample Common Program can be named and stored as part of an ALL, a PATTERN or a SONG data file (.R2A, .R2P, or .R2S) and it can be loaded separately if you select LOAD, then select the “SMPL” as your load type and look in the “Common_Samples” folder.

The RS automatically keeps track of “Common_Samples”, “Pattern_Samples” and “Song_Samples” and lets you extract individual samples from within ALL, PATTERN, and/or SONG data files types. When a Pattern or Song has a phrase that points to a Sample Common Program – the RS will automatically associate the samples used with the Pattern they are used in. This way if you load the Pattern – you will load the samples.

The best way to archive your data is in ALL data files – because it is the most complete. It also lets you recover any portion of the data, for example, you can load a single Pattern from an ALL data file that contains 64 Patterns. You can load a single Song from an All data file that contains 20 Songs. You can recall any Local Sample (sample used within a Pattern or Song) or any Common Sample program from an ALL data file. Rather than save each Pattern individually to SmartMedia card – save an ALL file – this way it will not duplicate the COMMON samples for each individual Pattern save.
