Worshiped?

I would just say that some genuine experienced fellow would be appreciated to say the least. There must be some still alive I think. Is that truly not feasible? If so, could anyone explain why?
Any suggestion about coming up with someone that could build up the required skills and equipment? These are typical symptoms analysis that should be written down into some repair procedure. More information has to be collected as well, like schematics, test points and their typical readout: voltages, frequencies, wave shape. In fact, all this is the matter of a specialized organization. And I know that efficient servicing facility can only be achieved by someone close enough from the repair activity.
If one of us is ready to put his/her hand on a and manage to know how to , then I will be confident in our ability to repair a damaged device. All this talking comes from my previous life experience of the field. That's why I can tell that I am not able to do it myself.
- I know that I don't know what has to be known to do a good job.
- Does anyone knows/wants us to know he/she knows?
