Pure Evoke Mio Radio Replace OLED Display

The Evoke Mio is a cuddly DAB radio bound in mock leather. PURE have a legacy of building DAB radios since the early 2000s.

My particular model was manufactured in Nov 2008.

OLED was chosen by PURE as a low energy display in favour of its eco credentials, however it was not evident at the time that these displays have a finite lifespan.

I am hoping this post will help others replace their OLED displays. Much of the inspiration came from Alan's web page- credit to him for making the post for others to follow.

PH2,PH1 philips screwdrivers

Flat head screwdriver (small)

1. Charge up your battery so that you can test later

2. Disconnect the battery and the power

It's not obvious how to open up the Mio, there are no externally visible screws. However, the age old trick of hiding the screws under rubber feet at the base has been used by PURE. First step is to use a flat head screwdriver to get 4 rubber feet off, then unscrew.

Carefully lifting the cover reveals a power cable to the battery terminal. This can be unscrewed to release the base.

There's some sound deadening fluff which should be removed.

3 PH2 screws are holding the back panel- unscrew these but wait until the next step to take it off completely, as it is still attached by 4 cables

Carefully detach the 4 cables before lifting off the back panel

This will expose the front... which you should remove from the carcass by unscrewing 3 more screws

It should be possible to keep the aerial cable attached (it is soldered and glued) between the back and front.

Detach the speaker cable

Unscrew four screws in the corners of the PCB

Remove the plastic knobs from the front panel, and unscrew the two nuts

Use a small flat screwdriver to open the tabs on both sides of the OLED display ribbon to free it up, then gently pull it out

After the PCB is lifted, you will see the ribbon cable attached to the OLED component which sits underneath a fixing panel which is secured with two screws. After this panel is removed you should be able to replace it and test then re-assemble in reverse order!
