Replacement of HV transformer.
Two types of high voltage transformer are used (removable or fixed focus cable). When replacing a line
transformer, replace using the original type.
Type Focus cable Part no.
A Removable 1-453-169-12
B Fixed 1-453-220-11
DEFLECT
Lines tearing when hot.
[32in models only]. Replace line driver transformer T804.
No sync in TXT mode.
Replace IC1001.
PICTURE
Horizontal interference in picture during first half hour.
IC606 is defective. Therefor unstable +9V (pin 3 of IC606). Replace 9V regulator IC606.
Ref. Description Location Part no.
IC606 LM2940T-90 D-board PSU 8-759-267-25
Visible arcing interference on screen when appliance does function. Intermittently switches off when switched
on.
Replace line output transformer T803.
Partially blanked horizontally.
Check zener diode D817 (RD5.6ESB2) in blanking circuit, for leaks.
Overbright, nearly negative picture.
Access service mode and enter TT07 to clear.
AUDIO
Hum and/or buzz of the headphones and/or speaker when vol. is low.
Deflection unit generates interference. On board A, solder side, add a thick wire AWG18 200mm long between
pins 6,7 and 8 of IC203 and pins 29 and 30 of CN1. Given its critical position, the wire must be kept away from
board A.
Part no. Ref.
190090227 Wire AWG18
No sound. Headphones OK.
Fau;t 1: [PS6001 O/C]. Replace audio output chip IC1200 (TDA7264).
Distorted or loud crackling from audio.
Check audio demodulator/processor chip IC202 (MSP3410).
