Did Casio damage samples with its own FZ1?

This is about how the fading backlight EL panel behind the FZ's display among other weird behaviour of the FZ1 sampler might have corrupted early FZ samples. Recently I downloaded these files from: http://www.warningwillrobinson.com.au/Sound%20libraries/Casio/FZ/ Yes, our highly regarded moderator G...

Re: Roland D-110 dim backlight

Well done again! Getting the display fixed is wonderful. jxalex only told me when asked to do it carefully but I expected something of a magic trick like with the q-tip and some isopropyl alcohol. Okay, it's obvious now but you did it and brought the broken lines back to life. I'm impressed. Next ho...

Re: Roland D-110 dim backlight

HOwever I need some brains for much tougher delicate experimenting. The worst scenario so far I have seen is in Korg Triton Rack. Its backlight wont fade away, but its LCD is nuisance which has glued ribbon-cables. Their connections depend on temperature, they break down, loose contact from LCD. Ma...

Re: Roland D-110 dim backlight

Thanx for replying promptly. Okay, that's very plausible but it doesn't give me enough confidence to sacrify a good working LCD. However, I must have a garbled LCD laying around somewhere that was detached from the PCB. Let's see if I can achieve some improvement on that one by carefully realigning ...

Re: Roland D-110 dim backlight

(preliminary) SUCCESS!! :lol: http://i68.tinypic.com/11qojn8.jpg Well done! Congrats =D> Now if you connect the new display with all lines visible exatctly the same you're there. I don't think the display in the pic where the rubber contact was disconnected from the PCB can be mended. jxalex said h...

Re: Roland D-110 dim backlight

Just checked, CN1 pin 1 goes to 1602xxx-2.1 pin 1! No need for the anode and cathode connector. About mounting the new display so it is positioned rightly behind the fron panel I made a bracket out of an aluminium profile that I had laying around to replace the original one: http://i64.tinypic.com/3...

Re: Roland D-110 dim backlight

Why the tracer of the flat cable goes to pin 2 instead of pin 1 on the LCD board: http://i66.tinypic.com/169px88.jpg you may think encircled pin is pin 1 (and the blue tracer is actually going to pin 1 on the D110 board), but when you flip the module over in the longitudinal direction: http://i65.ti...

Re: Roland D-110 dim backlight

Changing led or whole backlight panel? ALso just changing out the backlight behind the element is not so much work, the LCD still gets back correctly in its place with the rubber conductors to glass and no need to change the all unit altogether. I changed a backlight panel once this way but the char...

Re: Roland D-110 dim backlight

You got it right the first time [quote="logix"]Oops! I just took it for granted that it was a direct pin-pin replacement since the pin-layout looked the same and this particular LCD was suggested here, but having just compared the LCD pinouts from the D-110 service manual and the new display's PDF I...

Re: Roland D-110 dim backlight

Pin 1 and 2 are the same as original DM029Z LCD.
The rest is: ERM 2.1/DM029Z-3/4-4/3-5/6-6/5-7/8-8/7-9/10-10/9...13/14-14/13.
Then you'll get the digits.

Re: Roland D-110 dim backlight

UPDATE: Robber1956 , I see you posted the pinouts earlier for a different display. Is that pin swapping in relation to the pinouts of the original display (in the D-110 service manual), meaning that the pin numbering/signal description of the CN1 connector (see below) is correct? http://i68.tinypic...

Re: Roland D-110 dim backlight

Hi, thanks for referring to the data sheet. The the resistor's colour code (white/black/brown/gold) says, according to an online calculator like this: http://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-resistor-color-code-4-band it's a 900 ohm resistor and yes it is som...

Re: Roland D-110 dim backlight

Also pin 1 and 3 are bridged as can be seen on the second picture form logix. Why I don't know yet. Everything is fine with the 1602A. Perhaps one should do the same with the ERM1602SYG-2.1. Another thing is the firmware, latest for the D110 is 1.13 The benefits of upgrades are not always spectacula...
