This similar three-in-one Philips set belonged to my neighbor living opposite to my house. He brought it to me with the complaint that the Radio was not working and the CD was also intermittent. I had attended to this set a few months back, when the problem was found due to dust collection in the function switch.

 

I had then opened the set, cleaned it thoroughly and just lubricated the switch and found everything working just fine. So, this time, I dismantled the set like in the two cases referred to above.

I did a thorough dry solder patch up of the boards (the picture above is after doing that work) and replaced all the electrolytic capacitors as most of these were out of the permissible ESR readings.

Then checked the functions one by one; Radio, USB and CD and found these to be working.

So, refit the boards back to its case and checked the set thoroughly for several hours before giving delivery to the customer.

Here is a picture of the defective components:

Mission accomplished with satisfaction getting added to its collection!

   As always, well Parasuraman.
   Seems to be a popular model and you are the right man for the job.
   Also, good lesson regarding the uController from the other article.
   These are things that may come to mind in the future if I get similar errors.

   This is why these articles are so invaluable.

   That is a lot of capacitors to be replaced, I hope it was worth the time and money spent on this repair. Thanks for sharing and have a blessed day my friend.

   As usual, caps changing is your pleasure .I'm trying to emulate you,as changing of caps goes a long way in refurbishing these appliances.Changing about 49 caps neatly is commendable.Thanks for sharing sir.
