Funai Computer Speaker Intermittent No Power Repaired
Customer brought his Funai Speakers for repair with the complaint of intermittent no power. First I have checked the power adapter and it was producing 19 VDC and working fine. I had to open up the speaker for further troubleshooting.
Once the cover was removed I found one of the variable resistors (potentiometer) was broken.
The customer confessed that he accidentally pressed on the variable resistor and causing it to loose and drop out.
After visual inspection on the loosen parts, I found there was nothing wrong with the variable resistor and I reassembled it.
After installing back the variable resistor I removed the “On / Off “switch and cleaned it with Contact Cleaner and resoldered the joints.
I then powered it up and no longer have intermittent power problem and the sound was good too after attaching it to the computer.
