I recently accessed the service menu on my Thomson TV to make some minor adjustments to the geometory setup. While I was doing this I noticed a load of other options and adjustments whose names were meaningless to me. Can anyone enlighten me as to what they do? Here they are... Setup: STD - BLI, B, BDLI, BD, I Invar - On or Off S Bright - (variable slider) S Colour - (variable slider) T Contr - (variable slider) Text Lang - 1, 2, 3, 4 Tube Type - 16/9, 4/3 WWS - On or Off Dec PR04 - On or Off Geom: Volt H VCO V Pos V Amp V Lin H Pos H Amp Trap EW1 EW2 Video: R Cut G Cut R Drv G Drv B Drv Some are fairly obvious but if anyone can help with the less obvious ones I would be very grateful.
