Subject: [akaiS1000S1100Samplers] S1000 Display Issue

Hello all - my name's Brian - I'm just starting to dabble in sampling and figured an S1000 was a good way to start... however, I've got a problem. Upon powering up, the display on the S1000 blinks solid gray for a second then returns to the all-blue colour it has when it's off. I was under the impression if this was a backlight issue I'd still be able to see text on the display albeit unlit and vague - but I'm not certain, that was just an assumption. Is it really the backlight that's the problem, or is there a bigger display problem I have to deal with here? The rest of the sampler seems to be functioning alright - an operating system disk makes various loading noises and seems to work fine - except since I haven't actually USED the thing and can't see anything on the display I have no further means of testing the rest of it... any help would be greatly appreciated cos I'm psyched to eventually be able to use this.

Someone else here may know this better then me but I was told you can adjust the power on the inverter board if the display starts to appear faded.

You can have a look at this page how to open your S1000:

This site also sells backlight foils.

Hi Mike,

I recently worked on an S1100 in which the LCD backlight inverter was
making an unusual amount of noise.  The inverter circuitry was potted
in a reasonably firm, but not hard, polymer of some kind, inside a
thin plastic injection molded case.

I found that by squeezing it I could quieten and sometimes silence it.

This is all work for an electronic technician, because there are
dangerous voltages inside the machine and because of the risk of
static electricity damage to the circuitry.

If you mention this to your technician - that it may be possible to
squeeze the inverter with cable-ties or whatever, to make it quieter
or silent - then they may be able to solve your problem.

Regards

Can anyone recommend a part number to use as a replacement inverter?

My S1000 is emitting a high-pitched whine sound, and the consensus on the boards seems to be that it's an inverter issue.

Hi. I have changed the LCD in my Roland D50 for a vfd. The display looks good but the contrast is set On full. This is because the contrast is meant to be software controlled (from firmware) but an LCD is voltage controlled such as the pot on the s1000 front Panel. I Only mention this as it is an extra point to watch out for when converting to vfd units.
Regards Carl.

Hi
PeWe
the display was an old Noritake sample unit I had lying around. The current model looks to be the Noritake CU40025-UW6J (available from Farnell Order code 1495418 £84.32).

I originally started the project because I was changing the old low intensity green LEDS in the D50 LCD display to much brighter PLCC2 style SMD Cyan LEDs, this was successful and I had to back off the brightness a bit as the light was showing through the dark sections as well. Unfortunately whilst documenting the 'mod' I knocked the display glass off the workbench and broke the corner off ( shame) hence the VFD was worth a try.
The brightness control situation was not implemented electronically and the unit defaults to max brightnes, but you do need to put some dark filter material in front of the glass anyway to get a good light/dark contrast. I just added two layers of filter material to make it viewable.

Incidently, the LED mod would have been successful if I had not been clumsy enough to knock the display off the bench. The LEDs were mounted onto a thin piece of stripboard and replaced the original LED backlight board. You do have to dissassemble the entire LCD module (PCB/Glass/elastomers etc)to get to the LED board, this is the bit that makes it tricky.
I will post some pictures later maybe on the D50 forums

thanks
Carl

Hi PeWe!

If only your display foil is bad why don\u2019t you just install a new foil? It bet this is cheaper and works fine normally.

You can ask on this site for special sizes:

Hi PeWe!

They do not only sell classic inverters but also electronic inverters that should avoid the disturbing switching sound\u2026

Have a look under \u201celectronic inverters\u201d

Hi PeWe!

In Germany a cheap source for EL-foils is sometimes Conrad (Yes, normally quite expensive I

found that they have cheap EL-foils!).

Have a look here:

http://www.conrad.de/ce/de/FastSearch.html;jsessionid=95FFED8F0130E7951DCEE9710BD4520A.ASTPCCP11?search=el-folie&initial=true

Remember that you can cutt hem with scissors and for example the Akai S1000 the foil is too small. So I laminated the EL-foil between

Laminate foil and cut it afterwards to the correct size.

The width is not the optimum width for the Akai S1000 but the pixel area is bright\u2026

So it is a cheap compromise\u2026

Peter
