Conseils de reparation
Attention! (bloc secteur de commutationl
Utiliser uniquement       la pice originale 3447 00 04 (COO6). Dans le cas de

en plus.
1. Lorsque 1'6tage final horizontal est dbconnectb (par ex. raccordement          8
   sur TK02 ouvert) et dans le cas d'une charge de remplacement            au
   niveau de la cathode de V031 (lampe B incandescence             de 100 W) le bloc
   seteur doit delivrer 100% env. des tensions de consigne.
2. Pour la detection d'erreurs en fonctionnement         de s&uritb du bloc
   secteur, il est possible de ponter CO07. Lorsque le fonctionnement          de
   sDrete est d&lenchb B cause d'une surcharge transitoire, I'appareil peut
   gtre remis en marche au moyen du commutation             principal mise en et
    hors circuit.
3. Veiller B la presence de tensions continues exemptes d'ondulation.          La
   tension d'onduiation de Ui par exempie est de 4 V env. et ne devrait pas
    beaucoup augmenter en raison d'une perte de capacite de C033. Les
   tensions d'ondulation des autres tensions continues devraient toujours
    dtre infbrieures B 1 V. Les tensions d'ondulation de U2, U3, U5 se situent
    dans la gamme des mV.

2. Feed in RF signal without sound carrier with 70 dBuV on a medium UHF
   channel via the aerial input.
3. Go to service menu 1 (see service mode).
4. Use cursor button A or v to select AGC-adjustment.
5. Connect oscilloscope (bandwidth > 50 MHz) to the tuner's IF output, test
   point XL03 or XL04 and to ground XL02
6. Use cursor button 4 and)      to adjust to 400 mVpp f 50 mV with
   reference to the signal's synchronizing    peaks.
7. Use the OK (M) button to store the value in memory.
