Hi again to all of you.
First ,with your help,I want to see IF the audio IC YD 1517p is good.
So,I will attach the datasheet of the IC .
Turning the TV on, I have checked the voltage using the multimeter,the values are:
Vcc=12 to pin#7
1/2Vcc=0 to pin#3
Rest of the pins voltage=0.
Turning the TV off, In diode mode by multimeter with the black probe to GRD and red probe to the pin
#1 value is 796
#2 it beeps
#3 value is 796
#4 it beeps (why?)
#5 it beeps
#6 value is 792
#7 value is 1755
#8 starts from 1800 and goes to OverLimit
#9 value is 797
#10 to #18(the last pin that the IC has) it beeps cause is the GRD.
Turning the TV off, I have checked the resistance Ω(ohm mode) by multimeter with the black probe to GRD and red probe to the pin
#1 value is OL(over limit)
#2 value is 0
#3 value is OL
#4 value is 10 Ω ohms
#5 value 0
#6 value is OL
#7 value is OL
#8 value is OL
#9 value is OL
#10 to #18 value is 0
Based on this measurements please give me a hint about what is your idea if the IC is good,or guide me to do other measurements,or technics using the multimeter,beacause I only have this kind of measurement tool.
Are the above values correct?
