3 Alignments and Adjustments
3-1 Ser vice Instr uction
1. Usually, a color TV-VCR needs only slight touch-up adjustment upon installation.
Check the basic characteristics such as height, horizontal and vertical sync.
2. Use the specified test equipment or its equivalent.
3. Correct impedance matching is essential.
4. Avoid overload. Excessive signal from a sweep generator might overload the front-end
of the TV. When inserting signal markers, do not allow the marker generator to distort
test result.
5. Connect the TV only to an AC power source with voltage and frequency as specified on
the backcover nameplate.
6. Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure
that the power cord is disconnected before replacing any parts.
7. To protect aganist shock hazard, use an isolation transform.

In almost all cases, the X226B is backward compatible in software and functionality with the X226A. In addition,
the X226B has the following significant feature enhancements over X226A:
Support for Simultaneous DVI (YCbCr601/YCbCr709/RGB) Out and DAC (YPbPr) Output on the Primary Display
with Constraint Image
- Support embedded CGMS-A (EIA/CEA-805, EIA-J-1204-2) information in the primary DAC HD YPbPr Output.
- Support 50Hz capture and display (but no frame rate convention from 50Hz to 60Hz, or vice versa), complaint with the
EIA/CEA-861-B standard for DAC Out and DVI Out, and the ANSI/SMPTE 295M-1997 standard for primary display
DAC Out only
- Support 12-bit or 15-bit DDR DVI Output up to 80MHz pixel clock with separate HSYNC, VSYNC, DE polarity control,
dither 10 bit to 8 bit for 12-bit DDR DVI Output, and flexible On-Screen Display (OSD) indicators.
- Support 8-bit ITU-656 Out HREF and VREF (DVSHREFC and DVSVREFC) on DVSYDATC(8) and DVSYDATC(9).
- Support Video / Video Alpha Blending using Global Alpha on PIP Windows at Video Scalar Output on Primary Display path.
- Support non-linear horizontal anamorphic scaling on secondary and third video scalars (besides primary video scalar).
Support programmable 10-bit lookup table for gamma correction on the primary display
Support "Serrated Edge Removal Algorithm" (SERATM) that performs motion adaptive jagged edge correction by removing
objectionable artifacts on moving diagonals of Standard Definition (SD) interlaced content
Support 24-bit SDR and 12-bit DDR PC Graphics RGB Input for DVI IN up to 108MHz pixel clock.
Wavegen to improve PLL pulling/stepping for HDTV mode - Use the fourth primary DAC (DAC3) to digitally synthesize a
pullable clock, route through external filters and input to PLL (through new LPBK_PCLK pin or IDE_DMARQ pin).
Bi-directional I/O 2nd IR Port for HDMI CEC signaling.
Additional Pin Multiplexing:
- DVI Input 12-bit DDR or 24-bit SDR input DVICLK from GPIOB(7) instead of GPIOA(13), and DVIHSYNC from GPIOB(6)
instead of GPIOB(7).
- Smart Card B SMVCCB multiplex through GPIOA(13) instead of GPIOB(6) to avoid conflict with DVIHSYNC above,
and swap SMDETECTB from GPIOB(18) to GPIOB(19), and swap SMDATAB from GPIOB(19) to GPIOB(18).
- DVI Input 24-bit SDR upper 12 bits data multiplex through IDE pins.
- DVI Output 12-bit or 15-bit DDR multiplex through one bit Graphics Alpha on FlexBus, Smart Card A and Shopping,
and 1st IR pins to avoid conflict with DVI Input on GPIOB bus, and avoid conflict with FlexBus FAD[15:8], FCEb(1) and
FALE(1) for NOR flash and POD host. For 12-bit DVI Output, optionally, NRSSCLKA can be used as a GPIO pin
(e.g. HDMI Output CEC function implement in GPIO instead of new IRBIDB pin) instead of being used as DVI Output Monitor
Sense (DVOMSEN).
- Either graphics alpha bit 2 to 0, or DVI Out DDC I2C multiplex through VCXO & PWM ports.
- Added GPIO capability on FCEb(1) pin (e.g. HDMI Input CEC function implemented through GPIO instead of through the
new IRBIDB pin).
- 3rd Serial Port/UART Port C multiplex through new RDC/TDC pins to avoid conflict with DVI Input on GPIOB(3:2).
- FlexBus Interrupt FINTR(6:4) multiplex through GPIOA(4:3,12) pins to avoid conflict with DVI Out on Smart Card Shopping pins.
- FRDYb multiplex through FCEb(1) pin to avoid conflict with VCXO_INB pin or DVOVSYNC on FRDYb pin.
- Display loopback PLL clock LPBK_PCLK input on either new LPBK_PCLK pin or IDE_DMARQ pin from DAC3 output
through external filters.
- 2nd IR multiplex on new RDC/TDC pin to avoid conflict with DVI Input on GPIOB(3:2).
- Bi-directional I/O 2nd IR port on new IRBIDB pin.
