SAFETY PRECAUTIONS
•
Do not change any module unless the set is switched off.
•
The mains supply side of the SMPS transformer is live. Use an isolating transformer
•
Servicing of the CTV set should only be carried out by qualified person.
•
Components marked with warning symbol on circuit diagram are critical for safety and
must only be replaced with an identical component
•
Power resistor and fusable resistors must be mounted in an identical manner to the
original component.
•
Discharge the capacitors like Main Filter when working on these.
•
Do not solder when the set is on.
•
Do not connect any external device like Speakers etc. when the set is on.
•
When any signals are to be connected/ disconnected switch off the set.
•
Wear
rubber
shoes/non-conducting so that your body does not become a passage for
electric current.
INTRODUCTION
:-
VE01 chassis is capable of driving 14”, 20”, 21”, 21”PF tubes at appropriate currents. This
chassis is capable of working in the PAL / SECAM / NTSC systems. The sound system is
capable of giving 1.5W r.m.s. output into a load 8E speaker. One page simple TELETEXT,
TOPTEXT and FASTEXT is provided. The chassis is equipped with 21 pin scart connector which
can accept via scart the SVHS format from VCRs.
The details of various sections with IC details and pin voltages are covered in this manual. The
alignment procedure in field and also at manufacturing line is also covered in detail. The block
diagram, circuit diagram and track side layout of VE01 chassis is also attached in this manual for
easy reference.
