Hi Louis, Potentially, we might be able to help but would need as much information as possible on the failure (what is failing exactly) and would need a very close cooperation with the customer to isolate the failure site.

Some of these displays, too many from the manufacturer's perspective, are failing in operation. The display uses 3 printed circuit assemblies: a power supply, decoder of the information from the touch screen, and an interface to an external computer. No design information is available to the manufacturer. Would anyone suggest a person or organization who could study these assemblies, in the absence of design information, and propose a failure mechanism(s)? I have speculated that thermal imaging could help by comparing failed and surviving assemblies. Foresite's specialty may not pertain to what may be simple, low-speed assemblies, but I am prepared to learn otherwise. Thanks for any advice or comments.
