How to enter Service Mode to Televisions - Various Brands

Service Mode / Factory Mode Entry Procedure to different brand Televisions.

Chinese Sets

Hold down (Volume down) on set and press 'Recall' on remote.

'Recall' is the button that activates the channel number and clock onscreen.

After you have made your changes, in most cases, pressing 'POWER' on the remote will clear (Exit) the factory mode.

On some models pressing the 'AV' button will revert things to normal operation. 

In rare cases, the sequence first described above  (Vol - on set and recall on remote) will have to be repeated at least once more.
If none of the above methods works, try using a universal remote - best one that has a LOT of in-built models.
Search through the available models looking for any that suddenly causes the set to change channels.
Lock this setting into the remote and press '2'.
Factory mode should appear.
