TV Player Controller
TV Player is the controller for TV LED display. It connects the video processor with the LED display and
transfers HDMI signal to LVD. It has a RS232 and standard RJ45 port, 5V power supply input (LVDS signal
cable can supply power to display without extra 5V power supply, 2 HDMI input ports and LVDS output
port. HDMI input ports are digital interfaces based on 1.3 protocol, supporting HDCP decryption. HDMI I
has higher priority than HDMI II. Signal will input per HDMI I when there are inputs on both ports and
input will shift to HDMI II once HDMI I is damaged. TV player can support 2D and 3D video source. Max
input resolution is 1920*1200@60p; output resolution is different from input resolution after TV player
transfer. Below is input/output resolution datasheet:

Installation Features and Demands
The Leyard TVH Series screen is a sophisticated display device. Consideration should be given to the
site’s environmental conditions including load bearing of indoor installation location, spatial
distribution and so on. The method of installing the frame in this program has the following features:
•
Low weight, high strength: structure frame should apply aluminum alloy profiles splicing
together; punched aluminum plate should apply to install connection elements to lower the
installation structure’s weight and make sure the safety and reliability.
•
Modular design: structure frame apply to single component splicing together, but the weight
of each component shouldn’t more than 50 kg, which is convenient to transport and carry.
•
Convenient installation method: joint of frame all apply screws and bolts, which can install fast
and no need wield on site and then have little effect to engineering and decoration of site.
•
Demands of installation accuracy:
A. General demands: flatness of each linear meter is no more than 0.1, display unit gap is
no more than 4% of pixel pitch, and error of each linear meter is no more than 0.1 mm.
B. Light the first line cabinet after completion the installation to display the factory color
(30% of blue),standing on the cabinet joint away from screen surface R(800 mm* pixel
pitch ) observe whether there are bright line, black line in cabinet joint, if there is,
adjustment should be done to achieve the demands and then do the next work.
C. Standing on the location away from screen surface R to observe the screen vertically
and after the cabinet joint conforming to demands, observe the vertical joint with the
same distance along the direction that parallel to the screen and check the flatness of
cabinet. If there are some dark lines, which means the flatness need to be adjusted to
required value.
-----------------------------------------------------------------------------------------------------------------------------------Leyard TVH Series LED Video Wall User Manual 7/19/2016
15
D. After doing above correctly, touch cabinet inside with hand wearing antistatic gloves
to make sure the flatness, if there is uneven place, then adjustment should be done to
make it even.
E. If there is are no problems, you can continue to install the next line cabinet and light
them to check the joint of these two lines of cabinet using the same method with C
and D; if it is perfect ,you can keep continuing and lighting to check until the
completion of the whole screen.

Instruction of Indicator Lights on the Back of Leyard TVH Series Products
Each Leyard TVH Series product has five LED indicator lights in all. Seen from the rear view of the
cabinet from left to right, they are FPGA2, FPGA1, MCU, POWER1 and POWER2
1. Status lamp of FPGA is the combination of FPGA2 and FPGA1
a. When both of the two lights are flickering slowly at the same time; LVDS input of FPGA
in the cabinet is not working.
b. When the two lights are flickering slowly alternately; LVDS is working but no signal is
input.
c. If FPGA2 is flickering quickly but FPGA1 slowly; LVDSIN1 has input signals at present.
d. If FPGA1 is flickering quickly but FPGA2 slowly; LVDSIN2 has input signals at present.

2. MCU light status
a. If it flickers quickly when it’s powered on; the cabinet is loading the correct data.
b. If it flickers slowly when it’s powered on; cabinet is reading the corrected data back
from the lamp panel.
c. It flickers when parameters are set up or the corrected data are sent.
d. When the lamp is powered on successfully, the MCU light will work normally. If no
command is received, the MCU light will not illuminate.
3. Power light status
a. If POWER1 lights; the direct-current power supply of J15 works.

Toubleshooting
Fault Description
Troubleshooting
Screen doesn’t show images
1. Check 220VAC power supply of display is
working. Check power distribution box is
working.
2. Check video signal of display is good. Check
signal output of processor is not black
mode. Check signal input of DVI, VIDEO and
RGB are not black. Check if there is image on
Synchronous video monitor.
3. Check if TV player receives signal. Restart TV
player to check if signal indicator works well.
Part of screen doesn’t show images
1. Check power supply of faulty parts. Check if
power distribution box works well. Check if
PSU of cabinet works well.
2. If power supply is working well. Turn off
screen, wait for 1 min then turn on screen to
initialize faulty parts.
3. Signal connection problem between
cabinets. If the above 2 solution can’t fix the
problem, turn off power of the faulty
cabinets then change signal connection
cable or driver board. If image after replaced
driver board doesn’t match the surrounding
image, set software location, brightness and
color value.
4. Check if TV player receives signal. Restart TV
player to check if signal indicator works well.
5. Check video signal of display is good. Check
signal output of processor is not black
mode. Check signal input of DVI, VIDEO and
RGB are not black. Check if there is image on
Synchronous video monitor.
-----------------------------------------------------------------------------------------------------------------------------------Leyard TVH Series LED Video Wall User Manual 7/19/2016
52
Images on part of LED are flickering
1. Signal connection problem between
cabinets. Turn off power of the faulty
cabinets’ then change signal connection
cable or driver board. If image after replaced
driver board doesn’t match the surrounding
image, set software location, brightness and
color value.
2. Check if input image has problem. Check if
the image is different from that on
synchronous video monitor.
Module works abnormal. Whole or part of
module is lack of color, long bright, or not in
control.
1. Initialization of display unit is abnormal.
Restart power supply in this area with
interval of not less than 1min and
sometimes, this fault can be removed by
restarting it 2-3 times.
2. If the fault remains unsolved after Step 1 is
conducted, it preliminarily indicates that the
fault may be caused by poor contact
between LED module and adapter plate,
which can be solved by re- plugging and
inserting them again.
3. .If the fault remains unsolved after the
aforementioned two steps, the LED module
or driver board may be faulty, which can be
solved by replacing LED module or driver
board. If LED module is replaced, the
coordinate, color and brightness shall be
adjusted to be consistent with color of
image.
Remarks: When replacing LED module of cabinet, the factory calibration data must be saved in the new
module; after LED module is replaced, the cabinet will read the calibration data of the new lamp panel
during first start-up and therefore, the startup period is longer than usual; please be patient.
