Tuscan LED rear indicator repair

[Speed 3]

I have had an intermittent non-operating fault on one of the rear indicators for a few weeks (no jokes about intermittent operation by design). I've swapped the pair to confirm it is the LED unit itself rather than a wiring or ECU problem. I wanted to get it tested/repaired but Elmwood have tried a couple of places that do TVR ECU's (including Paul S) and neither can do anything. I suspect its a dry joint or some sub-component. Given they're no longer available and rare as rocking horse droppings used (even with the breakers), is there anyone out there that has any electronics ability to play around with it and rectify for me ?
