Working
principle analysis
RF
signal from antenna is sent into TUNER301 to be processed by HF-amplified and
frequency mixing, then IF signal is outputted to SWF Z301 to be IF filtered to
get ideal IF characteristics, then the signal is sent to main chip N101(RTD2674S)-27#,28#
to be amplified by inline IF amplifier and synchronous demodulated to get CVBS.
Video and audio signal from AV and YPbPr are sent to main chip N101 directly; video
and audio signal from VGA and HDMI1, HDMI2 are also sent to main chip N101
directly.
Main chip N101(RTD2674S) is a special large scale IC with full functions, such as
HDMI interface process, video decoding, video switch selection, A/D and D/A
transformation, interleaved/successive scans, mode transformation, OSD and
low-voltage difference output process, etc.; furthermore, it also has functions
of audio selection and process, MCU, etc.; external video signal is processed
by main chip N101(RTD2674S), then 4 pairs of difference signals and one pair of
clock signals are outputted to LCD to display; external audio signal processed
by main chip N101(RTD2674S) is sent to sound amplifier N501（ TAS5711） to be amplified
and then to speakers.

White balance adjustment
Before adjustment
The unit should be working for above 30 minutes to be in stabler state; Use
apparatus CA210 to adjust white balance;
For model of which dimension is bigger than 26”, only 9300K color temperature
(that is “normal”) is needed adjustment, To guarantee BBY test requirements to
be met when color temperature are 12000K and 6500K, make sure that chromaticity
coordinates of bright scale are (X=285±5, Y=293±8) and chromaticity coordinates
of dark scale are (X=285±8, Y=293±12);
For model of which dimension is 26” or smaller than 26”, only 8000K color
temperature (that is “normal”) is needed adjustment, To guarantee test
requirements to be met when color temperature are 9300K and 6500K, make sure
that chromaticity coordinates of bright scale are X=295±5, Y=305±8) and
chromaticity coordinates of dark scale are (X=295±8, Y=305±12);
White balance adjustment of HDMI channel

temperature adjustment” of factory menu;
For model of which dimension is bigger than 26”, select “normal” color
temperature (that is 9300K), fix item “G Offset”, adjust items “R Offset, B
Offset” to set chromaticity coordinates of the 3rd scale as （ 285±8, 293±12） and guarantee luminance within the range of 3 nit
to 5 nit; fix item “G GAIN”, adjust items “R GAIN, B GAIN” to set chromaticity
coordinates of the reverse 3rd scale as （ 285±8, 293±12） ; adjust items “R Offset, B Offset” and “R
GAIN, B GAIN” repeatedly until chromaticity coordinates of both scales are all （ 285, 293） ;
For model of which dimension is 26” and small than 26”, select “normal” color
temperature (that is 8000K), fix item “G Offset”, adjust items “R Offset, B
Offset” to set chromaticity coordinates of the 3rd scale as （ 295±8, 305±12） and guarantee luminance within the range of 3
nit to 5 nit; fix item “G GAIN”, adjust items “R GAIN, B GAIN” to set
