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!

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?
