Repair notes

 

Full repair description and observations

 

1

 Since the problem is only when the stations are viewed, but not when viewing, I believed that the tuner needs to be replaces, while the sound output fault was due something in the sound IC and circuitry

 

 

2

 When I went to HE Electronics to ask for the tuner, and explained the symptom, he assured me that the tuner was OK, but the IC TDA4502a was the fault.

 

 

3

 I replaced the IC (using also a base to make the work more neet) and the fault was cured

 

 

Repair summary
