Procedure to check up color TV electrical parameters

2.1

Audio

2.1.1 Output power at 10% THD

C

onnection through external video and audio input

a)

TV setup in “PP” condition.

b)

Connect a color bar generator (PAL-M system) to video input.

c)

Connect an audio generator with 500mV

AC

 level and 400Hz sinusoidal

frequency to audio input.

d)

Connect to the power amplifier output a resistive load with equivalent Ohm
value of speaker used on the tested TV.

e)

Connect a AC Voltmeter/Distortion Meter to the resistive load and increase
volume control until Distortion Meter reading be 10%. Measure voltage on
the resistive load and calculate power through next equation:

P = (V²/R)

Where “V” is voltage in VOLTS, “R” is resistive load in OHMS and “P” is
power in WATTS.

2.1.2 Residual Audio

a)

TV setup in “PP” condition.

b)

Apply 60dB

µ

V signal (frequency and channel factory defined) to antenna

input modulated with white pattern at 87,5% and audio signal with 400Hz
frequency modulated in FM with 25kHz deviation.

c)

Connect an oscilloscope to  power amplifier output (connect for the
speaker).

d)

Adjust volume to minimum.

e)

Use the oscilloscope to measure peak-to-peak voltage, in Volt peak-to-peak
(Vpp).
