1. Control program
1) The entire LED screen is not bright or perhaps grid
Control of your host open regardless of whether Communication line is blocked or not
Sending credit card has been plugged or not
The data line of multimedia minute card, capture card, transmitting card is attached well or not.
The particular switch position regarding JP1 or JP2 card is not ok?±,open the host
The connection line plugged nicely
To re-insert the sending card
Connect the particular lines well in the multi-media card, collection card, sending card.
Altering the JP1, JP2 switch location
The protection of a personal computer monitor is good you aren't or display screen will be black or glowing blue. (Synchronous Screen)
2) Each time when start LED manage system is not able to discover COM port to transmit data between the signal,the acquisition card line is not connected or perhaps the computer COM is defective. Connected to the info line or replace the computer
3) The entire screen shake as well as double image, Inch to check the data line between the computer as well as screen.
Check the DVI cable television between multimedia minute card and sending minute card
"Sending card is defective"please reinsert or perhaps replace the signal wire, to reinforce the port associated with DVI cable, or replace the sending card.
Only two. Drive part
One) Module can not gentle
Horizontal direction associated with few modules usually do not light, check the normal and abnormal element cable connection can be well or not.
As well as 245 chip is ok or not.
Vertical direction associated with few modules do not light, check the power way to obtain this line is alright or not.
+5V or GND is or not.
+5V or GND will be short-circuit or not
2) The particular horizontal direction associated with modules or the corresponding module is not vibrant or abnormal exhibit
To check the foot associated with corresponding module can be pin-line signal leakage or even welding, To check the signal at risk, the next is no welding or perhaps resistance welding leakage.
Several) Two lines of just one modules is vibrant at the same time(one of collections is normal, the other lines is bright continuously when display text.
Please check if related two lines is actually short-circuit or not.
4) The 1st half or the better half , red or green do not lighting or do not exhibit properly, it is insufficient color for each component, please check 245 R.H B output is alright or not.
Check the regular output of 595 feet and also abnormal 595 feet is actually passed or not
To view whether input toes is ok or GND, +5 Versus is short-circuit or not.
LED Display Screen FAQ and solution
1. Whole screen does not work (black display screen)
(1) Check power supply
(2) Check signal connection (cat5,DVI cable television) (synchronous screen)
(3) If synchronous display, check the green led associated with sending card as well as receiving card whether it is twinkling or not.
(Some) Check the monitor of Computer whether it is protected as black,or display screen area is black or pure orange. (synchronous screen)
2.Complete LED display module does not work(black unit)
(1) Successive modules throughout horizontal do not work, please check the ribbon cable tv between the normal unit module and unnormal unit unit whether it is connectted or not, as well as replace the first element from right side when facing your screen. (2) Successive moudels in vertical do not work,book the power supply of each of the modules.
3.One particular row lamps involving module does not work.
(One particular) Check this row no matter whether connecting to output pin of 4953. (A couple of) Check 138 encoder.
(3) Check 4953.
(4) Check Vcc and GND of 4953.
(5) Check output of 74HC138 and 4953's controlling pin whether connectted you aren't.
4.Unit module doesn't work.
(1) Check 595 typical or not.
(2) Checking the up and down moudle corresponded common flag connect or not.
(Three or more) Check 595 output pin for you to moudle pin connect or not.
5.One colour lacked in half or whole LED panel.
(1) Check 245 Third, G, B data output.
(2) Check regular 595 output pin along with unmoral 595 input pin whether it's connectted well or not.
LED Module Crash and Solution
1. Phenomenon: the whole display is flickering.
Issue: signal poor interconnection. Solution: re-fix or re-connect indication cable.
2. Trend: dusky LED
Problem: The voltage of switching power supply can be inconsistent with LED voltage draw. Solution: make sure the voltage of switching power supply is in step with LED. voltage tag.??
Several. Phenomenon: partial LEDs do not work.
Problem:
The. contact direction proper or not.
B. output wiring correct or otherwise. C. power insert anti-inserted or connected inversely.
Solution:
A. re-connect in a correct way.
B. ensure the red wire connect the beneficial pole,black wire connect the bad pole.
C. verify partial the wrong interconnection , re-connect.
4. Phenomenon: almost all LEDs do not work
Problem:
A. no production of the switching energy.
B. wrong energy connection.
solution: A new.connect the power change input and test.
B. check the bad and the good pole of the power whether it is right you aren't.
