This CD/USB Player was brought to me by a Lady with the complaint that the CD was not working. Checked my records and found that this had visited my workshop in June 2016 for the same complaint. That time, I did not find anything wrong except dry solder and loose contacts in connectors. The set had passed all tests being done as preventive, which included ESR checking of all electrolytic capacitors.




I opened the set, dismantled the whole unit including front panel and cleaned it thoroughly. Checked the board thoroughly and retouched wherever I suspected dry solder. ESR of 8 capacitors were nearing edge so replaced it. Cleaned the lens and lubricated all the contacts and also replaced the strip wire as it had shown strains. Tested it keeping it outside. It worked very well.

I had shorted the CD Lid open switch on the board, without which the CD won’t play. Noticed that if I stop and remove the CD and put another CD or DVD, it showed error. This is because, the details of the CD read and stored in the memory do not match with the one I put. Whereas, in normal case, if we open the lid, this memory is erased by the uController, when it gets signal of lid open. That was not happening here, as I had soldered the joints. This is something that I learnt or rather refreshed while servicing this CD player.




Checked with various CDs and DVDs, USB and Radio. All worked very well. So re-assembled the set, after removing the shorting of the lid open switch.

Tested the set both on CD and USB for several hours. It worked very well.

Another job completed to my utmost satisfaction. (I had forgotten to click the replaced components exclusively, but you can see it in the first picture above, in a small green visiting card box, at the top right side!)

    Another tedious job you've done by dismantling the internal drive for further tests out of the box Parasuraman. Seeing these portable sets I always wonder why these sets are so round and curved. Once only old cars were big, curved and round. As most modern equipment became small rectilinear and rectangular shaped. Making it possible to stack sets on top of each other. Which is also what makes these portable sets much harder to repair.
