No

Remote reception is 

insensitive or fails. 

Check if the remote 

control works properly.

Check battery 

Check  R1 R2  on front board

Use an oscilloscope to check 

if there is output waveform 

from the first pin IR of the 

remote censor after pressing 

button on the remote control. 

IR1(PIN 3 - RCwaveform) 

Check if there is IR 

signal on pin 44 of 
U2

Check if the power 

supply voltage to the 
remote censor is normal
