Why Twinking And Shaking Displaying On LED Screen?

Publish Time : Jan 17 2020

We continue to introduce how to solve common failure of LED screen.

Question: Why my LED screen is twinking and shaking?

Failure Cause:
a) Ground wire break down
Solution: Check the connection between whole screen and the ground wire

b) Controlling System breaks off (Sending/Receiving Card)
Solution: Check if the sending card and receiving card is working normal (green indicator twinkling, red indicator keep lighting). If the green indicator is off or keeps lighting, it means there is no signal if the indicator is off, it maybe also because its power is off). Sending card will very seldom break down. If it truly breaks off, please change the sending card.

c) Wrong voltage for Controlling system
Solution: Controlling system input voltage DC 5V

d) Loss of signal in Signal cable (internet cable)
Solution: Check the signal cable (internet cable), reconnect the cable

e) LED studio Setting has problems
Solution: Reset the LED studio software setting according to the LED software Manual

f) DVI card setting mistake
Solution: Reset the DVI setting according to the Controlling System Operate Manual
