Modification Prescriptions d'alignements
à point 1. C.I. Alimentation/T.H.T (GSPD)
Procédure de réglage
A l'aide de R3358 (Ubat) régler la tension en fonction de l'appareil. TVR37… 101,5V
à point 2. C.I. Tube
Effectuer les réglages sur l'appareil à sa température norma­le de fonctionnement (env. 15'après sa mise en marche):
Contraste "84% = Echelle OSD maximum moins 4 graduations" – Luminosité "50%" – Réglage de tension de grille (SCREEN) "En butée à gauche" – R3919 et R3921 "Position moyenne" – Injecter une mire de noir à l'embase AV – En fonction de l'appareil régler les valeurs suivantes à
l'aide de chacun des réglages de Cut-off R3920, R3918
et R3917 aux entrées R.V.B. du tube:
TVR 37… 115V TVR 51… / TVR 55…: 140V
TVR51… 120,3V TVR55… 84,0V
Préparation
Alteration Adjustment Procedures
to point 1. Power Chassis (GSPD)
Alignment Procedure
With R3358 (Ubat) set the following voltage according to the different models. TVR37…101,5V
to point 2. Tube PCB
Allow the set to warm up (for approx. 15 minutes after switching on) and carry out the following adjustments: – Contrast "84% = maximum minus 4 divisions on OSD scale" – Brightness "50%" – Screen grid adjustment control (SCREEN) "left stop" – R3919, R3921 "center position"
Feed a black test pattern into the AV socket
– With the cutoff controls R3920, R3918 and R3917, set the
following levels at the R, G, and B inputs of the picture tube dependent on the TVR model:
TVR 37… 115V TVR 51… / TVR 55…: 140V
TVR51…120,3V TVR55… 84,0V
