display light problem solution

Display light solution

check output voltage condenser
number 1
zero to 4 voltage but no light
number 2
7 to 10 voltage but no light
number 3
14 to 20 voltage but no light

Display light solution

zero to 4 voltage

1 check output track with cool testing

2 check v batt to all 3 points then bypass
3 check switching system

A check v flash voltage on transistor or bypass

B check switch voltage on transistor enable point
C switching transistor resold or change
D check light UEM to transistor

4 light IC punch or change
5 amply coile change

7 voltage to 10 voltage solution

1 output tips track washer disconnect
2 amply coile makes or change
3 light IC punch or change

14 voltage to 20 voltage solution
1 check LED plus track condenser to LED connector
2 check LED ground track with keypad LED jumper
3 LED check or change
4 LED connector resold or change

check LED
A check direct track battery plus or ground with connectivity
B check power IC track with cool testing or connectivity
ager power IC se LED track kharab hoti hai aro keypad LED on hai too
Keypad LED power IC track transfer to display LED power IC track
