Number: O/01/01; o_tv011e
E-BS-SA_3501 (Online)
Possible complaint:
The TV set switches at times to standby and then after several seconds back to normal
operation.
Cause:
This failure may be caused by an uncontrolled oscillation of the CVBS input and a faulty
software library of the processor.
Remedy:
To eliminate this failure it is generally necessary to update the unit‘s software. For this
consult the table 1 (software assignment).
- Update the operating software of the TV set. The software required can be down-
loaded from the Internet.
For this consult also the Service Informationen ”General 01/01“ and ”TV 04/01“
(external).
In addition it is necessary to check and change if necessary the circuit of the
Feature module of older TV sets. TV sets and chassis which
do not
require a change of
the circuit are listed in the tables 2 and 3. The positions of the serial numbers of the TV
sets and chassis are described on page 4.
For the positions of the components concerned on the Feature module please see the
circuit diagram excerpt and the PCB illustrations on page 2.
- Remove the chip capacitor CC80209 (coordinates x71/y78) if provided.
- Connect CIC80000, Pin 117 with ground (e.g. chip capacitor CC80205 (coordinates
x71/y81), replace with a chip jumper, or solder in a wire bridge from Pin 117 to
ground).
