I was going to do a write-up on how to repair them but never got around to it and figured most people wouldn't care to do such a repair.
The conclusion I came to is the inner LEDs are probably getting more voltage than they should. The inner and outer LEDs are separate series circuits. The voltage reading across the outer LEDs shows 2.65V, and the drop across each one is obviously half, or around 1.33V. The inner LEDs on the other hand, the reading across all 3 yields 4.45V, so the drop across each one ends up as 1.48V. This doesn't seem like a huge difference, but it can be depending on what the LED is rated at. My guess is the LEDs are rated at 1.5V or the like, and Mayflash is pushing that to the limit which ends up in an extremely short life.
Here are some pictures I took during one of my repairs. There are no instructions or anything, I just quickly threw together an Imgur album. So far I've had to replace 2 LEDs. The ones I have laying around are much bigger which required grinding out a fitting space with a dremel, but they got the job done.

Hey bighead mine just went pop, any chance that tutorial could get written
I don't mind going to my local electronics shop for some components if they'll be more reliable/stable09-09-2015, 04:09 AM
