It sounds like Helen Oster is whetting our appetite about Adorama extending support for their Flashpoint brand to some (not yet existent) type of 'service' provided beyond initial warranty and beyond the optional 'New Leaf' warranty
Component-level service has not really existed for decades, but rather replacement of an entire module/PCB that contains the failed component. With integrated circuits embedded in the design, it is far too time consuming and difficult to find and replace a component, unlike many decades ago when a transistor or resister or capacitor or diode could be found to be the failed component. Now, replacement flash tube or hot foot or entire circuit board is the extent of repairs in most cases.]
But at the moment, if a flash falls and breaks its flashtube, your only choice (in the case of non-supported flash units with no service locations) is which trash can to throw it into...unless you can guess where to buy a flashtube with matching voltage and power capacity and form factor to risk DIY
There is another option, currently; at the end of the warranty period you can get the option of a brand new replacement at a good discount, because there isn't (yet.....) the option to pay for repairs/servicing. You only need email firstname.lastname@example.org for help with this.
