How I Repaired the OLED Display on My Pure Evoke D4 Radio

Wed, 15 Oct 2025 20:43:49 +0100

The display on my Pure Evoke D4 had been getting dimmer and dimmer over the past months — until one day, it simply went dark.
After some digging online, I realized this is a common failure with this model and its OLED display.

For instance, Alan Winstanley described the same issue with the Pure Evoke 1S in his detailed blog post.

Encouraged by that, I decided to repair mine.

Ordering a Replacement Display

I found what looked like a compatible display on Alibaba: 2024 OEM Pure Evoke 1S Mio OLED Display. After a couple of weeks — and a minor customs adventure — it finally arrived.

Now, time to open up the D4 and see what’s inside.

Making Some Space

Start by removing the six screws on the back panel of the radio. Once they’re out, you can gently pull the back panel away. Inside, you’ll see that the front and back halves are connected by several wires.

There’s one wire going to the handle, three flat ribbon cables connecting the boards and one wire from the speaker

To make things easier, we’ll disconnect all of them.

On the back side, gently pull out the white ribbon connectors — no need to use force.
They’re labeled CN1, CN3, and CN4, and the markings are present on both sides, so you’ll easily know where to reconnect them later.

Unplug the speaker wire.

Last, unscrew the handle from the body of the radio.

Next, remove the speaker (four screws).

Now you can unscrew the seven screws around the front panel to separate the front from the enclosure.

Replacing the Display

Here’s the interesting part: the display connector sits under a PCB in the center. To access it, remove the six small black screws holding the board in place.

You’ll also need to remove the volume and select knobs. Gently pull them off, and underneath you’ll find a small nut on each shaft. Use pliers to loosen them slightly, then unscrew them by hand.

The OLED display connects via a flat ribbon cable. To release it, use a small screwdriver to gently pull out the two black locking tabs on each side of the connector.

Now the cable should slide out easily. Once it’s off, you can carefully lift out the PCB.

With the PCB out, you’ll have full access to the display itself. Remove the two screws securing it in place.

Swap in the new display and align it carefully.

Reassembly

If you’ve been careful, you just follow the previous steps in reverse.

Now slide the display ribbon back into the connector (make sure the locking tabs are open). Once it’s seated properly, push the tabs back in to lock the cable.

Reinstall the PCB, the front panel, and all the screws. Reconnect the white connectors (CN1, CN3, CN4) and speaker wire. Reattach the handle, screw the speaker back in (remember, the magnet will grab your screws! A plier could be helpful to hold them), and finally reassemble the back panel.

Moment of truth

Power it up.

Success! The display lights up again.

However, I noticed that this particular OLED isn’t a perfect fit. It works, but it’s slightly offset.

When I looked at the original display, I saw its exact reference printed on the ribbon:

It’s marked RITdisplay 3003321506.
If you search for that reference on Alibaba, you’ll find listings for the exact model used in the D4 — which might be a better match than the one I ordered.

Final Thoughts

Replacing the OLED display on a Pure Evoke D4 isn’t difficult, but it’s not quite the same as the Evoke 1S guides you’ll find online.
If your display is fading, don’t throw away the radio — it’s totally fixable with a bit of patience and the right replacement part.

Now my D4 is back to life, and I can see the time in my kitchen again.

Fix Screensharing Icon Stuck in the Control Center on macOS

Sometimes, the screen sharing icon never disappears from the control center toolbar after using Screen Sharing in Slack, Google Meet, etc.

Screen sharing doesn’t seem to be active anymore. It’s just the icon that never disappears.

The trick to remove it is to restart Control Center:

Ivy on Walls

Sun, 06 Oct 2024 21:27:20 +0100

Ivy is “well-known” for damaging walls.

It is very common for ivy to grow on historic walls and there is much speculation about the damage it may or may not be causing. […] This report describes research commissioned by English Heritage (now Historic England) […] undertaken by the School of Geography and the Environment, University of Oxford.

Conclusion:

Roots damage stone, mortars, pointing: Depends on whether there are pre-existing defects in the wall – ivy can exploit defects not create them

Ivy is an effective microclimate buffer, reducing extremes of temperature and relative humidity. It also buffers against damaging frosts and filters airborne particulates.

And maybe, if nothing else, I guess it suggests that despite the soup du jour — huge seed/A rounds, massive valuations, binary outcomes— you can sometimes do alright by just taking less money and more time.

And a few gems:

Rob didn’t seem very impressed. He immediately dismissed the Urchin 2.0 interface as (and I quote) “too blue blue blue blue blue,” which I had to admit was true.

47-year-old Voyager 1 spacecraft just fired up thrusters it hasn't used in decades

Tue, 17 Sep 2024 10:57:30 +0100

Currently the farthest spacecraft from Earth, Voyager 1 is about 15 billion miles (24 billion kilometers) away. The probe operates beyond the heliosphere — the sun’s bubble of magnetic fields and particles that extends well beyond Pluto’s orbit — where its instruments directly sample interstellar space.

Earlier this year, engineers spotted an issue when the fuel tube inside one of Voyager’s thrusters became clogged. If the thrusters are clogged, they can’t generate as much force to keep the spacecraft steady. Voyager’s thrusters keep the spacecraft oriented in a way that it can communicate with Earth.

How to clean a stroller rain cover that got cloudy

Mon, 03 Jun 2024 21:20:07 +0100

If your transparent stroller rain cover becomes cloudy or opaque, don’t just buy a new one yet.

The trick is to grab some kind of oil and wipe it off on the entire cover with a cloth. Baby oil, pomade work well, as long as they are oily.

How to change the front-wheel bearings of a Yoyo stroller?

Tue, 16 Apr 2024 21:22:00 +0100

If the front wheels don’t spin as well as they used to, or if they become easily stuck, the issue is likely with the wheel ball bearings.

Yoyo sells spare wheel kits for 45 €. However, you may not need four new wheels. In the end, it’s as easy to just change the wheel bearings as replacing the entire wheel.

Some people mention needing a grinder, a saw, pliers… No, you just need a hammer and two screwdrivers.

Unscrew both sides of the wheel with two T30 screwdrivers.
One screw will likely become loose. The hollow one (the axle) will likely be stuck (as people complained). The axle got solidary with the bearings.
Screw back the male side back again, and with a hammer, hit on it. !yoyo-1.jpg This should push the axle out. It may break the bearing entirely but you were planning to remove it anyway.
There are two bearings per wheel. Remove the existing damaged bearings.
Replace the bearing with the proper replacement. !yoyo-2.jpg The bearing reference is 6900ZZ, and you can find it, for instance on Amazon.

VoiceOver will then use face detection to tell you how many people are in the frame. It will also say if a face is small, and where in the frame a face or faces are located incase you want to try and better center them. When you move, it will tell you the new framing, so you can figure out if you’re getting closer to the shot you want.

Updates - how do you make something great even better, I don’t know. But these geniuses obviously know. Can I add one more start? The new interface is more intuitive. Also like the latest addition of tags. Integration with iBooks, WiFi sharing, Facebook sharing. Magnifying glass? Oh my! (They even fixed the silly black screen bug) — An anonymous reviewer of Genius Scan on the AppStore who keeps updating his review with every new update. Thanks!

Over the last 3 years, I developed and iteratively improved Genius Scan for iPhone and several other apps (Genius Fax, Jotana, ShoeBox). I’m fortunate that some of them have been quite successful with Genius Scan likely to hit 10MM downloads this summer. While doing so, I learned a lot about iOS development and how to run a successful bootstrapped business through the iOS community. Here is my small contribution to the community (call it returning the favor) Useful information comes in different flavors but primarily helpful pointers and actual content. Hopefully, this will be a place for both.
