how to fix philips cd player no radio

This set was brought to me with the complaint that CD and USB were working, but no Radio. I opened the set and after cleaning up the inside, dismantled the whole set to check the PCB.

After touching up a few dry solder joints checked the power supply and components in the section and found these to be normal.

No ESR problems on caps too! (Very disappointing for me! LOL) Here is an extract of the schematic that I could download:

Found that the voltages to the Radio IC was also normal and audio signals injected at pins 23 and 24 (L-out and R-out) reached the speakers. Then chanced to look at the crystal from the top side of the PCB and the legs of it seemed to be corroded. Used a lens and confirmed it was indeed corroded and cut.

So replaced the 32.768 Crystal from my stock. The Radio started working very well! Reassembled the set after lubricating all switches and connectors and retouching the connector pins. The set worked perfectly well in all modes! Mission accomplished and satisfaction got added to its collection bag!

    Please find a way to post higher resolution pictures and schematics.
    Usually they are not readable and that is a big downside.

    Yes true. Maybe when anyone posts the links to the schematics that would help. The small resolution photos however is also something that is Windows 10 related. Because Microsoft even downgraded many tools like removing the old great photoviewer. That even if we re-installed the good old photoviewer it apparently was removed later on again! And many obligated MS Windows upgrades are a pain in the B..T causing problems that were added instead of solved!

    again my friend a well done repair job and I like the fact that in every article you always clean the device before proceeding with the repair. I usually do the dusting and cleaning after the repair is done and not before unless the dust is really bad in the device and components can not be recognized. thanks for sharing and have a blessed day

      That's because I am using my front bedroom converted as service centre! Moreover, I dislike handling boards with dirt and dust! Many thanks for your comments!
