1.14 The AM sound section for PAL/SECAMBGLL'- or PAL/SECAM BGLL'I setsConnect pin 3 of IC7125 to a fixed voltage levelof +2V by means of an adjustable power supply.Connect a signal generator (e.g. PM 5326) via acondensator 5p6 to pin 17 of the tuner andadjust the frequency for 32,4 MHz. Modulate(AM) the signal with 1 kHz.Tune the set in the UHF band and select systemFrance.First adjust 5106 for maximum sound output.Next adjust 5104 for maximum sound output.Adjust the frequency of the signal generator for30,9 MHz. and modulate (AM) the signal with 1kHz.Adjust 5102 for minimum sound output. Removethe power supply connection.
2. Adjustments on the picture tube panel (Fig. 9)
2.1 Cut-off points of picture tubeApply a black pattern generator signal. Adjustcontrast at minimum.Adjust brightness until the DC voltage acrosspotentiometer 3213 is 0V.Adjust 3207, 3220 and 3234 for a black level of125V on the collectors of transistors 7205, 7218and 7227.Adjust Vg2 potentiometer until the gun that firstemits light is just no longer visible. Adjust thetwo other guns with the respective controls(3207, 3220 or 3234) until just no light will bevisible.
2.2 Grey scaleApply a test pattern signal and adjust the set fornormal operation. Allow the set to warm up forabout 10 minutes. Adjust 3213 and 3214 untilthe desired grey scale has been obtained.
Black Hibri and Black Matrix tubes for Anubis Aand Anubis BIn the 17", 20" and 21" Anubis A and Anubis Bsets new dark tubes are used.These dark tubes do not require other electricaladaptions.

List of Error Messages
2. Error codes Anubis AIn the service manual Anubis A AC error code 3is not published. The error codes should be:
3. Main carrier .2 PWB for Anubis AAnubis A sets with production code PM 11 andQG11 are provided with a .2 PWB main carrier.This carrier implies the following changes:
Black stability improvement circuitry (Fig. 1)Compensation of the grey scale at contrastchanges by adapting the +160 by:- a new LOT (no winding any more between pin7 secondary side and pin 2 primary side)- a new driving circuitry at pin 2 of the LOT.If CONTRAST) Beam current EHT+160 Difference Vgt and kathode of gunBrightness . So if contrast up automatically thebrightness goes up, so stable grey scale.
Different LOT windingsThe LOT in a .2 main carrier PWB can beprovided with 2 different winding configurations:- if black stability circuitry, then a windingbetween pin 7 and 3 at the secondary side (aspublished in service manual Anubis A AC)- if no black stability circuitry, then a windingbetween pin 7 secondary side and pin 2 primaryside. Both configurations can be used in the .2main carrier PWB. In case the LOT is replacedby a LOT of the other type, the CRT panel, thefocus and the Vg2 have to be readjusted.
Sandcastle signal of the delay line IC7221(left top part of Fig. 2)The adapted circuitry optimizes the detection ofthe line time base component of the sandcastlesignal at pin 5 of delay line IC7221.VCR identification (Fig. 4)Function: Keep DENT present during VCR playback after switching off and on the TV-set again.Operation: The AEC at pin 21107015 is kept ata voltage inside the locking range (6V9) whenthe TV is switched on.
4. Main carrier .3 PWB for Anubis AAnubis A sets from production code PM12 and0G12 onwards are provided with a .3 PWB maincarrier. This PWB is published in this serviceinformation and implies the following changes:
Sharpness booster control or PQI circuitry(bottom part of Fig. 2)Function: More contrast during transients.Operation: This circuitry amplifies the black-to-white rising edge and the white-to-black fallingedge of the Y signal and superimposes thisamplified signal on the original Y signal.The sharpness booster control circuitry islocated on a postatamp print which is placed onthe main carrier in stead of the delay line 5251.The circuitry should be switched off in case ofbad aerial signals and for test patterns, and sois made switchable via pin 6 of the
(pin 6 is "low" for activated P01 and "high" fordeactivated P01; pin 6 previously was areserved pen for UV913 recognition which hasnever been used in Anubis A). The PWB of thispostatamp print is given at the last page of thisservice information.
Microcontroller with software version R165Software version R165 for Anubis A AC (TXTversion) TMP47C834N-R165 (107600; 4822209 33275) with:- an improved sleeptimer function- an "on/off" switchable sharpness boostercontrol (P01).The
C uses pin 6 for switching "on/off" the
sharpness booster (pin 6 is not needed anymore for UV913 detection). To enable the PQ1feature in the
C , the diode D6607 must be
added. 3W sound output stage (Fig. 3a and 3b)In the .3 PWB both a 1 W RMS mono (with 250loudspeaker) and a 3W RMS mono (with 160
loudspeaker) execution is possible with the newamplifier IC7157 TDA7056. In case of the 3Wmono execution the +9V supply line from theSOPS is different (see Fig. 3).Play back of copy protected VCR tapes (Fig.5, only for PAL only sets)Function: Enable VCR play back of copyprotected VCR tapes (prevent chroma flickering)Operation: Make the pull-in range of thechroma PLL more symmetrical and so thelocking time of this PLL faster. The adaption onthe chroma part is given in Fig. 5. In the syncpart (diagram B of the service manual) the valuechanges as given in the spare parts list areincorporated.Delay line IC7221 TDA4661/V2 (left top partof Fig. 2)For this new version of the IC the circuitry at pin13 is not needed any more.
