surely U.S. law does not allow Rogerson Kratos to have a monopoly on this servicing where they will not give service information to anyone else and then charge incredibly high prices?
You could fight this one for a long time Dick, before you won. Manufacturers will claim that their manufacturing/repair information is "commercially sensitive", and to hand out such information freely would be giving commercial advantage to others at the companies expense.
It took the vehicle smash repair industry in the U.S. a long time in the courts, and a lot of money, to force major vehicle manufacturers to release electronic repair information relating to vehicles, that the manufacturers had deemed "commercially sensitive".
The smash repairers declared it was costing them money to have to send vehicles under repair to dealerships, merely to deal with the likes of airbag disabling, and other extensive electronics in vehicles, that could have been done by the smash repairer.
As a result of the courts decision, the manufacturers were obliged to release a raft of electronics repair information - but not all it - because the courts did agree that some info was commercially sensitive.
Judging by the following employee reports, Rogerson Kratos can't justify their pricing on what they pay their employees - and it appears that the company is highly resistant to change. We all know what happens to organisations that resist change.
Rogerson-Kratos employee reviews
Sometimes you just have to bite the bullet and throw out a component that is not only unreliable, but unrealistically priced as far as repairs go. It appears you have plenty of choices for replacement of the Rogerson-Kratos unit, and most of them would appear to be an upgrade, anyway.
Never forget that electronics development is an area that advances extremely rapidly, and 5 to 7 yrs in the age of a component can often mean your "state of the art" component, is effectively obsolete.
