Is the popped capacitor obvious? Don’t they like blow up like a balloon when knackered? 

Look from the side the small ones tend to "dome" like this:

I've a few similar to this kicking about. This is the later one, does both Ni-MH & Ni-Cd:



As to what's inside:

 

[Sharpend]

I’ll take a look inside mine at weekend and post some pics if needed. Are the components readily available?

Sevenoaks & London. The caps have little crosses on top, it's like the weak point so they just "dome" rather split with a bit of force. 

Bit different to the bigger dielectric oil etc filled ones, they can really go (bang). 

Yes, generally bits are easily available.

Thanks Onoff, I’ll have a look and if can’t sort might take you up on your offer.

No worries. Whip the cover off and have a look. Just 4 Phillips screws.

Some chargers have air vents large enough to let swarf etc in and just need cleaning out to solve problems.

& the obligatory inside view:

Get that lid off and look at the caps side on!

Edit: I think I have the repaired one somewhere and written on the side in a Sharpie is "C1" or whatever that I replaced.

It was actually this really basic charger where the cap went bang. Ni-Cd only I think maybe.....



DFC & bar.

So pics as promised, no sign of Caps being blown? 

well I would if I could upload them? I get a limit of 501kb yet each pic is a few Mb? 
how do I reduce the size of pic?

how do I reduce the size of pic?

if I email a photo from my phone to my email address, the iOS Mail application asks how big I want the file to be, so it’s quick and easy to do

 

[Sharpend]

so here are the Pics Thanks to Andy, top and two sides, cant see anything obvious?

Thanks @Murdoch probably just as easy, didn't give that a thought TBH.

With the cover off and the unit plugged in and switched on I get the LED flash once GREEN, then I can hear a slight continuous buzzing (as though a bee has been trapped in a glass box?), putting the battery into the charger gives no lights or anything?
