Check this out, also :

So am I correct in assuming that, when ordering the display, I should choose the VDD = 5.0 V power connection and the 1 X 16 pin header options?

Ordered! $5.50 with shipping. Now I just need to wait 7-40 days for it to get here from China.

Cool ! Actually, you will receive it much sooner than 30 days, i guess...


Well, i found some time today and prepared a detailed "guide" for the TX7 display replacement.
There it is : https://synthnitz.blogspot.com/2019/...ght-guide.html

I will make a .pdf the next couple of days and upload it , too..

I hope it will be helpful for anyone who wants to perform this task.

nicely done, thanks. I'm quite fond of all my DX7 + related gear right now -- just about the only classic synth that's still very affordable. And still being used in new ways today!

Now, just waiting for the replacement display to arrive ...

Your prediction proved quite true -- 20 minutes was right. And that included the time it took to put Greg Hawkes "Niagara Falls" into the CD player, and vacuum out the spiderwebs.

Compared to changing the DX21 backlight --

- it's easier to get the TX7 open, simply because it isn't as large; any table will do
- it's easier to get to (and remove) the LCD display
- no bezel (glass) to remove/reuse

There are some plastic pins that can be a bit tricky to remove -- they have a center part to push in, before they can be squeezed through their metal holes ... but that doesn't really matter; they won't be reused, so they can simply be cut/destroyed. Not that they were so much trouble; I used a very small screwdriver to push the middle pin part, then squeezed them through with needle-nose pliers. The main issue really is that the plastic tends to get less flexible after 30 years, so it's a bit stiff to work with.

Really, the only part requiring any skill is aligning the display, which is simply a matter of checking how it looks powered on, then adjusting as necessary.

---------------------------------------------------------

Photos attached, illustrating how dirty it was (even *after* vacuuming), some rust, and of course the displays themselves. Pleasant surprise: battery clip already installed! So I won't have to do that.

New display looks so good, I may get a couple more TX7's and do them as well. What great, thick sounds that would be!

Hey, pardon the hijack...

Can any of you help me sort out how to use Dexed to manage Banks on the TX7?

I have both, both work individually, but I don't see where or how to do this.

Thanks.

Wow, JPogo, where did that rust come from at those output nuts???

Anyway, i love the way you aligned the display with just 2 screws with nuts. It is much more resourceful, quite smarter than using the standard metal brackets with the stock pins that i used. Shows some engineering skill ... Kudos , man!! i like it.
BTW, did you solder the white connector to the new display, or did you buy it like this?

Ah, you're giving me too much credit -- that's just how the kit was designed to be installed: re-use one of the metal brackets, forget the pins, just two screws to attach the bracket to the display. I guess that's why it cost $20 instead of $5

Anyway: no soldering. And I was quite happy to see the battery clip installed, which I understood to be not the original Yamaha way ...

I'll have to replace those rusty nuts (hm, is that a band name ??? ...)

Well, you are right, 20 instead of 5, because the maker of the kit did all the work so it would be a plug-n-play module.
Anyway, i see the lcd now is too bright for your camera to capture the characters !
Very nice.
Btw, i am thinking of making a tilted stand for my TX7 like your wooden one i see in your photo. (no room on my SY85...)
