Modern TV`s are not designed to be repaired to comonent level.
Specialist surface mount equipment would be needed and custom diagnostic stations.
Many repairs are done via software flash upadates.
There are not many of the old school TV reapair men left due to this but they still can make money repairing older kit and being up to date with their IT skills.
What you then have is the correct guy to deal with your fault.
I`d much rather have one of these guys deal with my B+O than some jumped up handyman who has been shown how to use the makers service tool and thinks he is qualified to tinker with mega bucks kit.
