Description of Input Mode Conversion:
This converter supports complete LVDS formats and supports conversion of various resolution ratio
input (6bit, 8bit, 10bit) into VGA signal (1280*720/60HZ), with favorable compatibility with various
displays. Conversion of LVDS signal formats is realized by pressing the mode button circularly.

It is prohibited to insert a shielded wire conversion board into a converter first. Instead, it should be
connected to a TV mainboard directly before switching on the TV mainboard. This operation easily leads
to shielded wire insertion fault and component damage. Please operate it based on the following steps:
1. Do not insert a shielded wire into a converter first. Instead, please insert the original shielded wire
of a TV mainboard into the converter. During insertion, LVDS signal wire sequence should be aligned.
After switching on the TV mainboard, the small board indicator light is on, indicating that the
termination of the shielded wire (wire sequence) is correct. Then insert the converter. It is
prohibited to insert the converter inside if the small indicator light is off; otherwise, the converter
might be damaged caused by the screen power supply entering LVDS input pin.
2. Generally, the single-route LVDS signal is able to be connected 0~3 (connection of group wire 4 is not
necessary) in Group A and clock input by selecting LVDS wire. It is possible to connect 5 pairs of
LVDS wire input. LVDS signal of Group A is able to support the resolution ratio up to 1366*768. LVDS
with two- or four-route is able to be connected to this group only.
3. The LVDS input rule of this converter follows PCB wiring rule of LCD TV produced by Skyworth, which
conforms to standard of LVDS format in the industry of color TV.
4. This converter adopts wide power supply at 5V-12V (1A) and supports portable power source at
5V/1A, so it’s convenient to carry for test.
5. Attention: LVDS input end of this converter should not have the screen power connected to any pin of
the LVDS input end; otherwise, it might damage the main chip of the converter. The main chip damage
incurred by this falls beyond the guarantee scope.

Converter:
During mainboard maintenance or commissioning, the original TV shielded wire might not match this
LVDS-VGA converter input interface. This issue is able to be solved by the shielded wire conversion
board. The high definition interface of the shielded conversion board adopts original imported interface,
featuring long service life. The conversion board is sold as an accessory of the LVDS-VGA converter.
Refer to the following drawing description for the shielded wire conversion board.
Diagram of usage of shielded wire conversion board:
Step 1: Do not insert the conversion board into the converter. Instead, insert the original shielded wire
of TV mainboard into the corresponding shielded wire interface in the conversion board.
Note: the corresponding interface is based on the twisted-pair position of the shielded wire and the
position of small board LVDS paired wire, i.e. insert it correspondingly. Different shielded wire should be
inserted into different interfaces.
Step 2: Use one hand to press LVDS flat socket tightly and use the other to clench both ends of the
shielded wire to insert it in. The figure above is the high definition shielded wire interface. The
standard definition shielded wire interface follow the such insertion method. (Note: operation of five
small boards are basically identical. During connection, attention should be paid to the wire sequence.
Align the power supply before aligning the twisted-pair LVDS wire of a shielded wire and the paired
signal wire of a small board.)
Step 3: Supply power to the TV mainboard. With a correct connection of a shielded wire, the indicator
on the small conversion board will be on; otherwise, it means connection of the shielded wire is incorrect

or the mainboard is not switched on. (Note: please inspect whether the mainboard screen power supply
(5 V/12 V) enters the right output pin; if it is, it will lead to a converter damage.
About an unfamiliar mainboard, a multi-meter should be used to inspect whether the contact pin enters
the screen power supply 5V/12V)
Step 4: It is able to be inserted (its front faces upwards) into the input base of LVDS –VGA only if the
indicator on the shielded wire converter is on.
Step 5: After connection, if the mainboard of TV is normal, the display or external display on converter
will display the image of mainboard of TV.
If there is no image, check if the shielded wire is connected well or if any damage of mainboard.
In case of a blurred image, press the mode conversion button repeatedly to convert to various modes till
the image is normal.
To facilitate the mainboard testing on site, a portable power source is able to be used to supply power to
the converter. It is actually measured that Mi 10400 power (portable power from other brand is able to
be selected) is able to supply power to this converter for 15 hours, fully conforming to testing
requirements

Precautions of Using Converter:
1. Please follow aforementioned operations strictly.
2. Firstly connect a mainboard with the shielded wire conversion board, with attention paid to the wire
sequence. Then switch on the TV mainboard, if the indicator on the shielded conversion board is on,
it means connection between the mainboard and the shielded wire board is correct; otherwise, it
should be re-inspected.
3. With correct connection between the shielded wire conversion board and the mainboard, insert the
shielded wire conversion board (front faces upwards) into the LVDS converter (refer to the figure
above) before putting the TV mainboard and the converter to switching on status.
4. In case of a blurred image, press the mode conversion button repeatedly to convert to various modes
till the image is normal.
5. This converter supports various LVDS formats (60Hz, 120Hz and 240Hz). About a mainboard with
two shielded wire, one wire alone is required to be connected to the high definition conversion board
instead of both wires. Besides, it is able to convert required image.
6. Please follow aforementioned operations strictly!
