Mini USB Bluetooth FM Radio Receiver Repaired
Problem Reported: Songs Playing through SAREGAMA mode (playing songs through Internal Storage) is not proper. Songs are intermittent skipping and through pressing volume up & down it changes the Modes instead of controlling volume.
So for inspection I have to open the unit.
After opening the Unit I removed the PCB from the BOX. On visual inspection no physical damage found.
There are too many micro switches. Cleaned All the switches using WD40 Spray.
Now removed Charging port PCB for Inspection.
On PCB I found One USB Pen drive is connected for internal song storage. I removed USB pen drive and connected to my PC and while checking File structure I found it showing some vague characters with file name which indicates abnormal condition.
And while playing files it does not opening these songs are in MP3 format. That means all the files were corrupted. I reformatted the USB pen drive and copy some songs from my collections. After all process now it is time to check the Unit for performance.
I have inserted the USB drive and placed the PCB on its location and turned on the unit and the unit is working perfect. Reassembled the unit after 15 Minutes of playing songs. Checked everything is perfect there is no skipping the songs and volume control also working fine.
Conclusion: USB Pen drive is got corrupted may be because of jerk / Loose connection as you see in picture there is no locking is provided. Note: Just forgot to apply hot glue to the edge of the USB Pen drive which keeps the pen drive on its place.
