Clip sport mp3 mp3 wont turn on

I love my Sandisk mp3s. I’ve had them for years, and never go for a run without it. On my 3rd now -a Clip Sport MP3. And it’s the same problem again that has occured. It won’t turn on or charge.
And yes, I have tried the long re-set by holding down the power button. Judging by the number of times I have seen it on forums, this is clearly a long standing issue.
The unit is approx 2 years old so probably out of warranty. Anyone else got a magical solution?

thanks in advance!
