20AF41 Service Menu

<< Back to Service/Designer Menu Page

Tip from ThomasL:  The 20AF41 and presumably the 24AF41 are different than the other Toshibas.

To enter the service mode:

  • Turn the volume down to 0.
  • Press the volume down on the front of the tv and at the same time press 9 on the remote. Wait a few seconds and the service menu should appear.   Make sure to write down the parameter/value pairs before changing anything. You can scroll through the parameters by using the channel up/down on the remote
  • Use the volume up and down on the remote to change the values.
  • Press Menu on the remote to exit the service mode.
