Answered Pure Evoke Flow Radio: Dim Display

So, I replaced the screen on our Avanti Flow yesterday. Whilst the guides I looked at on various other sites are undoubtedly factually correct, they all are, how shall we say, somewhat light on detail. I thought I would post my pointers, and some pics.
First off, dealing with the mesh covers. As other sites have pointed out the front and Sub Speaker grills are just interference fits. You would be advised to use either a guitar pick, or some of the plastic tools used in Mobile phone screen replacement kits to help get them out - unless you have very long and strong fingernails.
Secondly, remove the rear panel. It helps in getting more light in to see what is what. You do not need to remove any of the leads or cables from the rear panel. Watch out when you remove the speaker (4 bolts for the plastic trim which then reveals the 4 bolts holding the speaker - it is magnetic, of course and will try to attach itself to the metal insert in the wooden frame of the Radio. Remove the wadding - but with care, lest any of the wires or ribbons get caught. Definitely remove the screw holding the white cable holders - this will give you a lot more freedom when it comes to addressing the front panel.
Remove all the screws in the front panel (8 of them). Note that the screws are actually in parallel, so not following the curve of the front panel - remember this or you will round the heads of the screws. Gently pull the front panel out - but as the white ribbons start to extend, gently remove the tape which holds them together. You may also want to move the cables through the white plastic holders to ensure you have enough room to get at the PCB's.
Remove the first pcb, but leave it where it is. You will now be able to access the 4 screws to the second pcb. Make sure you are using small Philips screwdrivers - there is not much space, and you will need to access via the sub speaker cavity. The screws all have a touch of sealant to stop them vibrating loose, but this is easily broken.
You will almost certainly need to turn the unit over to gain access to the pcb screws.
I chose at this stage to remove the 2 gold ribbons which connect to the Screen pcb, plus the thinner white one on the other side. Take a photo, so you know where they go. As suggested on another site, probably best to use thin nosed pliers, with electricians tape round the jaws for ribbon removal.
There are 6 screws holding the Screen PCB and the mounting.
Once you get this out, make sure you know exactly how the ribbon folds and which may up the screen actually fits. Gently remove the foam cover from the plastic housing with your finger nail. Do not use a knife or screwdriver, as you may damage the pcb. Retain this so you can glue it back after fitting the new screen.
I had to trim the plastic housing to allow my replacement screen to fit. Basically there are 2 small tabs inside the housing which I had to remove on one side with an Exacto knife. Perhaps I was unlucky, just saying that your new screen may be 1mm wider than OEM.

Fitting the ribbon back into the screen pcb was a bit of a fiddle - again use long nosed pliers with tape on the jaws.

Refit the second pcb, and attach the ribbons. Note that the cables to the front speakers have a hard plastic and foam "gromit". These need to be reattached to the pcb posts. If you don't do it his way, you will struggle to get the front panel back in the case. finally screw the first pcb back in.
The front panel should now slide back in (snuggly).
Gently fold back the white ribbons (I didn't bother taping them back up), push through the cables and reattach the white cable brackets, which is a bit fiddly.
You can then refit the speaker (the wires are sized to fit the correct male/female) and trim, rear panel and the grills. They may have distorted slightly when you removed them, just be patient.

Switch on and enjoy a super bright screen!

Good luck. It took me over 2 hours to fit mine. I reckon I could do it in under an hour having done it once already. Hopefully I will not have to do it again for a very long time.

I am afraid that all OLED displays fade and expire in time. Like light bulbs.
My Tempus-1 (looks pretty similar to the Evoke-1) display is also very very dim, however I do not think its the display, rather the LED backlight mounted to one side of the display.
I got a bright torch and shone it in the area of the LED, and the display became more illuminated.
When you dismantled yours, did you note anything that would assist me in sourcing a replacement LED (which looks to be a straight forward soldering job I hope)

Anyone any idea where I could source a yellow OLED for my Evoke Flow? It was just readable up until now, unfortunately it’s now completely gone :(

I have a Pure Oasis Flow radio with an extremely dim display. Following the threads for the Pure Evoke with similar problems, I managed to buy a replacement OLED module for it from a supplier in China, but unlike the Evoke, the Oasis display seems very difficult to get at. I removed the 5 screws holding the main board which sits behind the display but the board will not budge, so I guess it's held in by something else, possible the 2 rubberized knobs on the front which don't seem to have any screws and will not pull off. Does anyone have any idea of how to remove the board so I can access the display ?

Solved the problem. You have to prise off (with care) the 2 Control knobs at the front which reveals 2 large nuts. Undo these and remove the 4 screws holding the board plus the partially hidden one at top of the board. Use a sharp knife to cut the copper shielding material linking the metal cans of the main board and small daughter board. Then wiggle the daughter board upwards to remove it from the main board. This reveals the 22 pin ribbon connection to the display and the smaller ribbon connection to the touch screen (it passes through a slot in the main board). You can now lift out the main board to reveal the OLED display in its plastic frame which you can unscrew and lift out. You can see the touch screen tracks fixed to the glass window - don’t touch these. Levering out the display from the plastic frame is tricky. The original display will have a copper sheath and ferrite bead around the ribbon cable. For the new display you won’t have these but go ahead and install the new display. The assembly is the reverse of the above but getting the touch screen ribbon through the slot and into its socket can be tricky. Always slide back the tiny plastic tabs on the ribbon sockets to release the ribbons, then make sure the ribbons are pushed well in and the tabs closed when installing. Make sure the daughter board is correctly aligned with the multi pin sockets on the main board before pressing the daughter board in. Finally solder a short wire to link the 2 metal cans before screwing it all together. All a bit of a nightmare but do-able !

Hello.

I own a Pure Sirocco 550 and I have the same problem as described in this thread.
Reading the messages, I understand there are two models of digital displays that are working with Pure Radios :
WEX012864DWPP3N00000 and WEX012864DLPP3N00000 on the "First Components" website.

Could someone tell me which one of those models can work with the Sirocco 550 ?
If one of these models is ok, do I have to buy the "display connector" as well ?

Thanks a lot for your help.

Hi, I have had a TEMPUS 1 for about 15 years and yes, the display has gone very dim, almost unreadable.
I have read all the previous comments about replacing the display. All of therm seem to be applicable to the Evoke model. Has any one replaced the Tempus display with the Evoke display?
I think the part number is quoted as WEX012864DWPP3N0000.
cheers

I was told by the China supplier that the same display is used in all these radios, although I cannot be be certain without actually seeing inside. The key things are the dimensions of the displays and the number of pins in the ribbon cable - the Oasis and the Evoke have 22 pins. Actually the displays are slightly too wide for the plastic holder in those radios, so some careful shaving of the side walls of the plastic holder is necessary (careful with that knife !) to make the display fit. Use double sided tape to hold it in position. I think you will find the difference between these displays (...DWPP... and ...DLPP...) is just the colour, the first being white, the second being amber/yellow. Otherwise, they are the same.

I can never understand why Pure are so mean about giving out part numbers and other technical information, relating to their products. Still, it's good that forums like this exist.

When I called Pure about trying to buy some parts, or get a schematic, they just said "No" and told me it would be cheaper to buy another radio ! Obviously the OLED display is "planned obsolescence".

Yep! Just about the same response that I had, when my Avanti Flow, completely failed. Although they did, initially, direct me to a Scottish repair company, who told me that they would no longer have anything to do with Pure or their products. They would not give me a reason.
The Avanti was replaced with a similar radio from Roberts, who were much more helpful when I had a problem with the battery.

Me too. The customer service ethos of the taken-over Pure is seriously lacking. Over the years we have accumulated 6 Pure products from the car DAB onwards - including my Oasis Flow on which the display has died. Trying to get any help from Pure was like talking to an obstructive brick wall. Should have searched here first :) I also found some info here which gives some background as to why Pure has changed for the worse. Alan Winstanley info on Pure display Roberts next time for me. I've found a display on Alibaba - just need to do bit more research to check it's the correct one and find an expert to do the twiddly bit.

This whole issue with OLED displays is quite "interesting". It seems the life expectancy is only about 8 or 9 years, at which point the display is so dim as to be virtually invisible. There is no backlight you can replace like in an LCD display, so basically the only option is to replace the whole display - but what about all these wonderful 4k OLED screens being offered by companies like Samsung, Sony, etc ? Does it mean after 8 years you have to replace the screen, no doubt being the major cost component in the whole TV ? Sounds almost like planned-obsolescence. Even old CRT's from the 1960's last longer than that.

Hi teeseetwo, I too have an Oasis flow with display issues, thanks for the detailed instructions on replacing the display, could you tell me the part you ordered and where from?

I found several suppliers for the display on Alibaba but few have any stock at any one time, you just have to email each one until you find one that has stock. The first 2 I bought were worse than the display that I had already, but they did only charge $5 each for them (plus shipping of course). But the next one (same supplier) at a cost of about $40 works fine. One word of warning, always run the display at minimum brightness, or set it to activate only for 7 seconds (that's the choice on the setup menu) after pressing any button, to get maximum life though as I understand it, 8 to 9 years is the maximum lifespan for these OLED displays.

Also set the display to 'off' when in standby mode. However I leave the display running on dim, when active, as I like to see the content information. EG track titles and artists for music.

Hi, the display of my Pure Evoke Flow can be visible only in complete darkness. A search on the web for a new display and found this WEX012864DW with no more letters or numbers: I enclose the photo of may radio (front/retro) and I shoul like to know if anyone knows if this display can fit on my radio. I don't want but the display is I'm not sure if it is the right one. The seller in Italy has no answer to this question as they aren't specialist but only seller. Thank you all. Ciao

This should be fine. Same radio as mine. Make sure that you specify yellow.

Hi, I am really struggling to find any supplier at all. Can anyone share a supplier that can defenitely send this display and not charge a fortune please?
