TKDMR TV-160 Generation of LVDS Turn VGA Converter With The Display LCD/LED TV Motherboard Tester Mainboard Tool
Manual of Sixth-Generation LVDS-VGA Converter (Attached with device)
Thanks for choosing Sixth-Generation LVDS-VGA Converter (Display screen version)
developed by TD Please read this manual carefully before using. During LCTV
maintenance and production, the mainboard is required to be connected to a screen for testing;
however, due to miscellaneous mainboard specifications, various screens are required for
maintenance or production. In this case, this converted is developed to reduce the pressure of
manually installed screen and prevent the screen damage caused by the output signal of mainboard
fault which leads to tremendous loss. Taking this into consideration, this converter is able to
display LVDS from the mainboard directly or convert it into VGA for output. Besides, it is able to
be connected to a displayscreen for maintenance and commissioning.
To test the motherboard than 32 LVDS signals, comes with display. After the host first powered on, and then use the original machine screen line, then the corresponding adapter plate, in the case of a short circuit board did not give the board power adapter plate lights, and then inserted into the adapter plate converter on the host, this time will be able to host the display shows the image output board.
I. Characteristics of this conversion board
1. Furnished with 4.3″ display screen, it is able to display LVDS image directly from the
mainboard, supporting external VGA.
2. It supports LVDS signal with various resolution ratios (60Hz, 120Hz and 240Hz) of single or
dual shielded wire.
3. It outputs uniform VGA signal (1280*720/60HZ) which is able to be connected to various
display, supporting CRT, liquid crystal and TV display (favorable compatibility).
4. The input interface features anti-static design with better anti-static capacity.
5. Convenient conversion among various LVDS formats.
6. Wide power input design, with 5V-12V adapter.
II. Packing list and standard accessories
Note standard accessories only include two normal shielded wire conversion boards, one
for two-interface with high definition and other for four-interface with standard definition. These
two conversion boards are compatible with most shielded wires on the market. Additional FFC,
special sanxing interface and another three mainboards are optional as shown below:
III. Select a conversion board (Please log in http://www.aliexpress.com/store/1937268 to inquire and purchase)
Note these three shielded wire conversion boards are not standard accessories, but they can be
purchased. The difference is that sanxing standard-definition conversion board with two
interfaces is thicker than the interface of configured standard-definition conversion board. The
other two FFC interfaces aim at conversion board with partial screen body being customized with
FFC interface. They have the same sequences with two standard conversion boards, but the
interface is FFC. The usage is shown at the back of manual.

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.

1. 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
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.

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.
