Error reader. The BE-3D chassis supports the use of the Error Reader. This jig, is available under part number S-188-900-10 (price code S). The displayed code shows the actual error of the TV set. Refer to the service manual or the table below for an explanation of those codes. ERROR CODES 02 - Protection circuit trip 03 - IIC SCL LOW 04 - IIC SDA LOW 05 - IIC SDA and SCL LOW 06 - Jungle/chroma controller no acknowledge 07 - Video switch no acknowledge 08 - Tuner no acknowledge 09 - MSP no acknowledge 10 - NVM no acknowledge 11 - M3L TXD LOW 12 - M3L RXD LOW 13 - M3L ENABLE LOW 14 - M3L TXD AND RXD LOW 15 - Compact Text test fail 16 - AV switch cannot power on reset 17 - Cannot initialise jungle 18 - NVM acknowledge fail after initialisation 19 - Multiple devices with no acknowledge 20 - Compact Text run-time failure 21 - AVSWITCH response failure after power up 22 - JUNGLE/CHROMA controller response failure after power up 23 - Compact Text does not respond 24 - Sound processor run time failure 25 - M3L bus clock low time-out after data sent (run time failure) 26 - M3L bus clock low time-out afetr data sent (power up) 27 - M3L bus clock low time-out afetr data sent (initialization) 28 - DSP run-time failure. 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).
POWER POWER
EHT comes up briefly then nothing. No error code. [Excess current protection system ope |
