Thomson 65UC6406 service mode required (Android TV)

[alltvrepairs]

Hi,

Just replaced the backlights of this set and want to enter SM to reduce permanantly a bit the backilght settings.

Cannot find the correct settings. This set has only 3 buttons on the bottom of TV as found many say press vol- and ch- together.
Thanks
