Abstract:
This report is about assembling of a color television. The parts are imported from China
and the assembling section of Shahnoor Electronics assemble those and if necessary color
television is taken under servicing department.
The television is made up of four principal sets of parts: the exterior part or housing, the
picture tube, the audio (sound) reception and stereo system, and the electronic components
(parts). These electronics parts include cable and antenna input and output devices, a builtin
antenna in most television sets, a remote control receiver, computer chips, and access
buttons.
The color television (CTV) assembly section was under the supervision of my mentor.
That is why I got the clear idea on assembling a CTV. I worked on attachment of felt sheet
to the front panel, setting main PCB (Printed Circuit Board) inside the cabinet, and
connecting the speakers. To ensure the better service for the customers, warranty sticker
on the back side of the CRT was placed. I placed the CRT very carefully by tapping four
screws at its four corners. Then I plugged on the wires of power cord, sensor, speakers etc.
sequentially on the main PCB. Few adjustments like color, brightness, contrast etc. were
performed by me. By using magnetic machine I also checked horizontal and vertical
adjustments. Sound quality, channel tuning, A/V input output ports were checked by me
before back cover docking. I performed ground test at the final stage of assembly. At
servicing station I did not have hands-on experience rather observed technicians doing
there jobs and for better understanding they provided me few flow charts so that I could
follow their works.
