Power-Off Codes

This page's purpose is to catalogue all known power off codes used with each revision of the WebTV/MSN TV product, their purposes, and how they can be triggered. This list is by no means complete or accurate.

Almost all information so far has been sourced from MattMan's page on known power off codes from his hacking site, with us at the moment merely adding in our own notes and information on previously-unknown power off codes for the MSNTV 2 (codes 8086 and 357).

First-Generation WebTV/MSN TV

To trigger power-off code, turn off unit and either press OPTIONS 3 times and then type out numeric code, or use the remote combo if applicable. The box lights should flash for a bit after successfully detecting the code.

LC2/Plus Codes

Numeric Code	Remote Combo	Function	Notes
314159	???	Disable secure download checking (used on pre-2014 builds as they don't support encrypted downloads)	Does 2014 = build 2014?
159753	???	Delete Disk Cache	N/A
48627931	???	Delete Group Database	"The client and service often want to check to see if broad groups of files are present and valid. This is done by checking groups, instead of individual files. Sometimes, the group gets out of sync with the individual files. This code destroys the group database, so the service will download everything again (IR, EPG, etc.), or at least take a look at individual files."
7445000	???	Delete Video Ads from Disk	N/A

Japanese Dreamcast

Power-off codes for WebTV for Dreamcast.

To activate, press the S3 key on the Dreamcast keyboard 3 times right as the splash screen appears and type in numeric code. Only some codes have been confirmed to work on WebTV for Dreamcast, others might not work on this release. The time window for entering in the code is also extremely small and not easy to predict, making testing the codes extremely difficult.
