• The TV will turn on with the Service Menu displayed.


• There are 5 category menus:
  Deflection - Signal - Feature - Fix Value - EEPROM

  Note: Not all models will have 5 categories.
  Some will jump to 'Signal' category.

Enter service menu by first unplugging set, then while holding both input button and volume down button, plug TV back in. Within about 5 seconds, the set will power up (without pressing the "on" button); keep holding the input and volume down buttons until a small "K" appears in a box on the left side of the screen. Then press and hold the channel down and vol down buttons at the same time to enter the service menu.

Once the service menu is displayed on the screen, you can get the screen to display different levels of solid grey by pressing the number keys on your remote. i.e. press "1" to get a relatively dark grey, 2 for a lighter grey, and so on up to 6 which is a bright white screen; 7, 8, and 9 don't appear to do anything. Press any number a second time to return to the service menu...
