Call Samsung tech support. They will refer you to how to make the purchase
for their service manuals. For most models, they will not sell the manuals.
As for doing adjustments, for many of their models, you will be required to
buy some of their tools. This you will find out, if you can have the service
manual for the model of your interest.

Many of the independent service people over here, jobber out equipment like
this type to the respective authorized manufacture service rep, and then
forward the quote on to the customer. This way, there are no service
headaches, searching for parts, investing in jigs, interfaces, and manuals,
and the responsibility of the warranty is passed on to the people that did
the actual service. Also, when considering the added cost of buying the
manuals, and any dedicated tools that are required, it pays to send it out
to someone who has invested in all this stuff, and is doing it on a contract
basis for the manufacture.

Does anyone know where to buy one and how much? I'd like to access the
service mode to do some adjustments. Thank you for your help.
