Digital Audio Player Repaired

Received SAREGAMA CARVAN portable digital music player for repair, stating not working. This unit is used by customer’s old age parents.

On testing I found the unit is not powering on by pressing On/Off switch on the top.

I thought may be battery is drained totally hence when I went to connect the cable for charging internal battery, I found missing micro USB charger connector.

So I disassemble the player for repairing…

Checked battery voltage it is showing only 1v hence it is not power up.

On removing the back side PCB found Ripped USB connector.

Traces found intact even though connector is damaged because of extreme pressure for connecting the charger cable.

For replacing connector space is very tight because of plastic part of the connector, it will easily get damaged while using Hot air …….so I decided to put the external USB Connector.

    Although installing a new micro usb connector was successfully done, it probably was still easily possible to just replace the bad original usb port on the board with a new one. This way avoiding having to make another hole into the case. Since the usb copper tracks were all fine. And that also could be made mechanicle stronger by using some hot melt glue to make the micro usb connector firmly stick to the board if need be. And removing hot melt is always still possible by heating up the old glue.

      You are Right Albert,
      But as i said this unit is used by old age parents,They always not sure how to connect the Micro USB pin proper way & by putting pin wrong-way they applying more pressure & chances are high to damage the port again. I thought so too to put DC Jack by modifying Adapter but customer is in hurry because his parents are Traveling next day to the native and it used to take time to arrange parts i utilize the parts i have for fast repair.
