Every documented remote sequence that opens a service, diagnostic, hotel or developer menu on LG, Roku, Samsung, Sony, TCL and Vizio displays, with what each item inside does. Pick a brand, or search all of them at once.
Photograph every page first and change only what you came for. Service and factory menus write directly to EEPROM/NVM: model and panel type, region, white balance and firmware sub-processor items can leave a display with the wrong panel configuration, a black screen or no boot. Reading values is safe. Red-tagged items are for a technician with the model's service manual.
Each page keeps its brand color, so you always know where you are. Bar under each card: share of items that are safe, caution, do-not-change and unverified.
The primary sequence for every menu. Use the brand chips above to narrow it; select a menu for the full entry on its brand page.
