Samsung has strict policies regarding warranty repairs. If you are an independent shop, Samsung will not give you their internal manuals unless you are a "Samsung Authorized Service Center" (which requires expensive certifications and insurance). However, to compete with big box stores, you need these manuals to fix out-of-warranty units efficiently. Guessing which capacitor blew on a Samsung monitor power board is gambling; reading the schematic is science.

Furthermore, the service manual is the gatekeeper of calibration. For devices like Samsung’s high-end OLED televisions or professional monitors, replacing a screen or a main board is only half the battle.

Without these instructions, a perfectly installed replacement part will still yield a substandard image. Thus, the manual ensures that repair restores the device to factory specifications, not just basic functionality. Samsung has strict policies regarding warranty repairs
