First, I little LCD background. To be able to see the display, there are 4 main parts. The front polarizer, the glass, the rear polarizer and a reflector. In the case of the 250 I had, both polarizers are fried.

Supplies:
Sprayer with 50/50 alcohol and distilled water
Stick on polarizer with matte finish (eBay)
Mirrored one way window tint film, or polarizer with reflective back
Utility knife
Hard plastic squeegee
Lint free cloth or wipes

Here are the steps.

Remove the clear cover, it's held on by 4 snaps
Lift off the rectangular surround on the LCD
Remove the black needle stop pin, then use a sharpie to mark where the natural resting spot of the needle is.
Use a pair of spoons to lift the needle off, getting the spoons as far under as possible.
Remove the black ring at the speedo stem
Pull back the 2 snaps on the left edge of the LCD, tilt the LCD up slightly and pull to the left.

With the LCD out, time to peel off the old polarizer.
Use a flat blade to gently lift up one corner, then peel back. Peel to the side, not up. A little heat from a hairdryer helps. Finally, use some iso alcohol to clean the glass of ALL residue.

Wear gloves, and do these steps where it's clean
Next step is to apply the new polarizer.
You will need a small squirt bottle with 50/50 ISO alcohol and distilled water.
Pre cut the polarizers to size, make them 1/8 inch bigger or so
After you cut the first, place it on the rest of the film with the adhesive sides together with the glass between. You should be able to see through, if it's black, you will need to rotate the uncut sheet 90 deg. Once oriented cut the 2nd piece. The film has protective films on both sides use a sharpie to mark the orientation and the not sticky side.
For the film application, reclean the glass, then spray heavily with the 50/50 mix. Peel the protective film off sticky side. It's hard to do, take a piece of masking tape and stick it to the film and use that to peel the backing.
Spray some more on the adhesive side.
Starting at one side lay the polarizer on, keeping it off the contact area. There should be no trapped air. Take the squeegee and from the center out gently press the trapped water out.
Although you can do it all at once, I'd recommend waiting a few days between sides, and layers. You might still see some water bubbles trapped, those will dry out. If they are still there after a couple days, squeegee again.
Trim the edges with the utility knife, with a pulling down motion so the film doesn't lift. Hold the knife at a 45 degree angle so the edge ends up chamfered.
Repeat for the other side, and mirrored film if used.
Finally, put it all back together, be careful with the 2 LCD clips, they have the tendency to lift the film edges.

Cool project. Did you take before and after photos of what the screen looks like then and now or are you not yet finished?

This was from recovering the milage off that really burnt screen. The polarizer was just held there, because I ran out of material, but I was able to read something when the original was completed unreadable. Eventually I'll get more material and use that one for experimenting or as an exchange for someone else's burnt screen, if they need help

This is what the inverted screen looks like. It was a bit hard to read in the sun, but looked cool at night

Pretty crafty. Big thumbs up! I'm sure most people would buy a whole new instrument cluster not knowing this is possible. Pretty darned good thread you started here. Unless there already is one this seems like it would be Wiki worthy.

how is that inverted look achieved? I think the stock red is too much at night. I like that inverted look.

When the front polarizer goes back on, you rotate it 90. That gives you the inverted display

This is reflective for the rear:

Search term: LCD polarizer back

I used 90 degree, the originals are 45 degree, but it doesn't matter since the film is oversized, and the alignment is relative to each other film.

I think doing the 2 layers on the rear with normal polarizer plus mirrored window film comes out better, but it has different look. For what it's worth I tried the red mirrored and it was too dark. Gold might look cool tho. You could also try a silver or white vinyl on the back.

Really clever fix! That is/was my fave instrument cluster of all Vespas. Even the current so-called digital display, doesn't deliver as much info.

How the heck did you figure that out, I was told it was impossible to fix.
How much would you charge someone with zero patience or the skill to do that?
I've been looking at the SIP Speedo but I hate to lose my original mileage at just 6k.
PM if you have an interest.

Cool scoot btw

So after a few emails back and forth with RacerATB he sent me a reconditioned LCD to replace my basically unreadable OEM LCD.

It took me about 2 hours to swap out and put back together everything. If you have some patience and some basic tools it is a pretty easy fix to keep your original mileage and knowing how much gas you actually have.

RacerATB was responsive and gave me some helpful hints while I was doing the swap.

If you have this LCD issue I would contact him for a swap.

The two pics are Night and Day shots of replaced LCD. For well under $100 you can now save your original Speedo. My local Vespa guy insisted it's impossible to Fix.

Thank you RacerATB!

Just wanted to express my gratitude for everyone sharing knowledge on this topic. I would have never tried this on my '06 GTS 250 without it so again thanks. I now have a perfect display.
I do have a question for those that might have had the same experience. When I took the speedometer needle off with a little force, a tiny plastic piece fell out. For the life of me I couldn't see where it came from so I left it out after re assembly. Everything works great now but the speedo needle is now a bit jerky, so I'm thinking this was some kind of counter weight on the inside of the needle hub. Any help is appreciated.

I do not remember seeing that piece but it was a while ago. I can say my speedo needle definitely is not smooth but I forget what it was like before I did it.
Mine was definitely dropped and taken apart before so who knows what they did.

They are the counter weights on the Speedo needle. They go under the center needle cover.

Thanks for the reply. You say they, is there two because I only noticed one fall out?
Also, do they just pop into the speedo needle Center hub?

Surprise fix... took my gauge pod to my boat gauge guy and after looking at it, he came back with this: "We didn't have to refilm this one. Just clean the ribbon connector. No charge. What was actually cleaned were the contacts on the PCB Board with Emory. Then a quick wipe of the silicone conductor."

I would say not well written at all. I tried repairing sun damaged lcd on my yamaha majesty after seeing this thread. ordered polarizing film for a cell phone. that didnt work. then tried dismantling some computer screens. surprised there is like 7 layers of film on those. got it to work but it was dim hard to read. polarised film is like a venetian blind. lets light pass at one angle. film comes in many angles 90, 45, 15, 0. and then there is linear film? all quite confusing when he says angle doesnt matter. and if youi dont know what angle is for the original then you dont know what the heck to order.. guess I need to research and read up far more.

What he said was that the angle doesn't matter if the film is oversized, because you can then rotate the film to whatever angle it needs before cutting it to size. You can see it in the pictures. Rotate the films relative to each other until they block the light completely. Then you know the little venetian blinds on the films are 90 deg to each other.
