MODEL NUMBER
CHASSIS SERIES
CE28R2-C-00
28R2/CE28R2-C
The service Precaution:
The area enclosed by this line
(
) is directly connected with
AC mains voltage. When servicing the
area, connect an isolating transformer
between TV receiver and AC line to
eliminate hazard of electric shock.
NOTIZIE SULLA SICUREZZA DI FUN-
ZIONAMENTO
Ogni sotituzione di componenti va fatta
tenendo conto della sicurezza di funzion-
amento. I componenti indicati sollo
schema con il simbolo /!\ hanno partico-
lare importanza per il sicuro funziona-
mento del TV.
I suddetti componenti devono essere
sostituti esclusivamente con quelli indi-
cati nell'elenco.
PRECAUZIONE DI SERVIZIO
L'area inclusa in questa linea (
)
è collegata direttamente con la tensione
della rete CA quando si serve l'area col-
legare un trasformatore isolante tra il
ricevitore TV e la linea CA per eliminare
il pericolo di scossa elettrica.
Product safety notice:
Product safety should be considered
when a component replacement is
made in any area of a receiver.
Components indicated by a mark /!\ in
this circuit diagram show components
whose values have special signifi-
cance to product safety. It is particu-
larly recommended that only parts
specified on the part service manual
be used for components replacement
pointed out by the mark.
Note sul diagramma di circuito :
1. Tutte i valori di resistenza sono in ohm,
K=1,000, M=1,000,000.
2. Tutte le resistenze nominali watt sono di
1/6 a meno che sia specificato altrimenti.
3. Eccetto per i condensatori elettrolitici, tutti
i valori di capacitanza di meno di sono
espressi in µF, e di piu di 1 sono in pF. I
varoli di capacitanza elettrolitici sono in
µF.
4. Tutti volt di capacitanza nominali sono di
50V a meno cha sia indicato altrimenti.
5. Tutti valori di inductanza sono in µH.
6. I valori letti del voltaggio presi con un
"VTVM" proven gono dal punto indicato
sulla massa del chassis, i valori di voltag-
gio presi usando un segnale di barre col-
ore sono con tutti i controlli alle loro
posizioni normali ed il commutatore AFC in
posizione "OFF". Il voltaggio puo variare
con l'intensita del segnale.
7. Le forme di onda furono prese con il seg-
nale di barre colore e i controlli regolati
oppure le forme di onda di immagine nor-
male furono prese usando un oscillatore a
larga banda ed una sonda bassa capasità.
8. Rispetto a quando indicato su questo
schema possono essere state introdotte
delle modifiche.
9.s I diodo 1S1555 possono essere sostitutti
con 1S2473, 1S2076 oppure DS472 a
meno che sia specificato altrimenti.
s I transistori possono essere sostitutti con
2SC536(Q,R,S), 2SC1740(Q,R,S),
2SC945A(Q,R,P) oppure
2SC1815(G,O,Y) a meno che sia speci-
ficato altrimenti.
s Il transistore 2SA608(E,F) puo essere
sostituito con 2SA933(Q,R),
2SA564(QA,RA), oppure 2SA1015(O,Y)
a meno che sia specificato altrimenti.
Circuit diagram notes :
1. All resistance values are in ohms,
K=1,000, M=1,000,000.
2. All resistance rated wattages are 1/6W
unless otherwise noted.
3. Excepting electrolytic capacitors, all
capacitance values of less than 1 are
expressed in µF and more than 1 are pF.
4. All capacitance rated voltages are 50V
unless otherwise noted.
5. All inductance values are in µH.
6. Voltage readings taken a digital voltmeter
are from point indicated chassis ground.
Voltage readings taken by using a colour
bar signal are with all controls at normal
position. Some voltages may vary with
signal strength.
7. Waveforms were taken with colour bar
and controls adjusted for normal picture.
Waveforms were taken by using a wide
band oscilloscope and a low capacity
probe.

REGOLAZIONE DELL'ALIMENTATORE B1
1. Regolare VR641 in modo che sia centro meccanico, prima
di premere l'interruttore principale.
2. Sintonizzare il ricevitore sull'oscillogramma circolare PAL.
3. Regolare i comandi di luminosità e contrasto sui livelli
normali.
4. Collegare il misuratore V digitale su "TP-B".
5. Servendosi di VR641, regolare il voltaggio su 130 ± 0,5 V
(per 21 pollici).
Servendosi di VR641, regolare il voltaggio su 150 ± 0,5 V
(per 25 pollici).
REGOLAZIONE AFT
1. Sintonizzare il ricevitore sulla stazione più chiara.
2. Servendosi di T141, regolare AFT per ottenere l'immagine
migliore.
REGOLAZIONE AGC
NOTA: Non tentare questa regolazione con un segnale
debole.
1. Sintonizzare il ricevitore sulla stazione più chiara.
2. Regolare AGC VR(VR130) nella direzione in cui appaiono i
disturbi da neve, quindi regolare in direzione opposta nel
punto esatto in cui i disturbi da neve scompaiono.
REGOLAZIONE DELLA SCALA DEI GRIGI
[REGOLAZIONE VR DI SCHERMO]
1. Sintonizzare il ricevitore sull'oscillogramma bianco.
2. Regolare il comando della luminosità su centro display e
quello del contrasto su normale.
3. Regolare VR2601 e VR2611 in modo che sia centro
meccanico.
4. Ruotare fino in fondo, in senso antiorario VR602, VR612 o
VR622.
5. Quando si tiene premuto il pusante tasto "Funzione" (sul
telecommando) e contemporaneameante si preme il
pusante P v (sul televisore) apparivanno le seguenti
indicazioni sullo schermo.
6. Premere il tasto "Funzione" (sul televisore) per selezione la
funzione "SCREEN".
7. Per regolar il livelli, premere il tasto livello.
8. Regolare VR di schermo per un solo colore in modo che sia
ben visibile.
[REGOLAZIONE VR DEL BIAS (POLARIZZAZIONE)]
7. Servendosi di VR602, VR612 o VR622, regolare la linea in
modo che sia bianca.
9. Per tornare al modo di funzionament TV, premere il tasto
Richiamo.
[REGOLAZIONE VR DEL DRIVE (ECCITAZIONE)]
9. Servendosi di VR601 e VR611, regolare il bilanciamento del
bianco.
REGOLAZIONE DI ALTO VOLTAGGIO E DI
AMPIEZZA
[REGOLAZIONE DI ALTO VOLTAGGIO]
1. Sintonizzare il ricevitore sull'oscillogramma circolare PAL.
2. Regolare i comandi di luminosità e contrasto sui livelli
massimi.
3. Collegare il misuratore V digitale su entrambi i terminali di
R224 (lato sinistro) (+), e il misuratore di alto voltaggio
sull'anodo CRT.
4. Confermare che l'alto voltaggio sia 25,0 ± 1 KV alla corrente
di fascio di elettroni 1,0, e meno di 28,0 KV alla corrente di
fascio di elettroni 0 (per 21 pollici).
Confermare che l'alto voltaggio sia 26,0 ± 1 KV alla corrente
di fascio di elettroni 1,1, e meno di 29,0 KV alla corrente di
fascio di elettroni 0 (per 25/28 pollici).
[REGOLAZIONE DI AMPIEZZA-H]
5. Se l'ampiezza H è troppo larga o troppo stretta, collegare o
scollegare un filo in piombo J213 (per 21 pollici).
Regolare VR462 per ottenere l'ampiezza H appropriata (per
25/28 pollici).
6. Riconfermare l'alto voltaggio.
REGOLAZIONE DI CENTRO-H
1. Sintonizzare il ricevitore sull'oscillogramma circolare.
2. Regolare il centro-H servendosi di VR361.
REGOLAZIONE DI CENTRO-V
1. Sintonizzare il ricevitore sull'oscillogramma circolare.
2. Regolare il centro-V servendosi di SW501.
REGOLAZIONE DELLA DIMENSIONE-V
1. Sintonizzare il ricevitore sull'oscillogramma circolare.
2. Regolare la dimensione-V servendosi di VR501.
REGOLAZIONE DELLA MESSA A FUOCO
Servendosi di FOCUS VR, regolare il controllo della messa a
fuoco per una buona scansione delle linee.
