    H4N , Zoom digital mic recorder , crackling ,advice please

    Hi All

    These seem to be quite popular , but first time i'm attempting to repair one .

    Customer mentioned a crackling coming through when using an external mic to record via XLR ports .

    What i have experienced is the unit being tap sensitive & crackling even without playback .

    Anyone have experience of working on these units ?

          Roland KR-3500/4500 Digital Piano. Crackling audio sound on all keys -Fixed
          by i_am_patch
          Hi All. I had a Roland KR-3500 Digital Piano (similar to the KR-4500) that exhibited a Crackling audio sound on all keys. After reading somewhere about someone with a similar issue who had replaced all the Electrolytic caps I decided to also go down that route. (Spoiler : It worked !) After some basic troubleshooting I determined that it could be noise feeding thru from the Keyboard scanning since the Demo tunes played back undistorted and the Audio amp / speakers were fine ( Inserted an Audio signal into the rear Audio input). After extracting the main board from the shield, I replaced 7 Capacitors...

          by sam_sam_sam
          When I originally started with my DVR recorder it had 4 individual switching switching power supply’s that were sh*t so I bought a 7 amp 12 volt switching power supply and modified the output plug and put a four output power supply cable to match the input power supply cable inputs

          Which worked for over 14 years until a few days ago when the cameras went dark no picture anymore well it turns out now the switching power supply has stopped working altogether now so I have to troubleshoot what has happened to this power supply more later on today what I found
