What to do if my Yamaha CDR-D651 does not switch on?
If your Yamaha Recording Equipment does not switch on when you press the POWER button, the AC power cord may not be connected or not completely connected. Make sure to securely connect the power cord.
Why does the remote control not work with my Yamaha CDR-D651 Recording Equipment?
If the remote control for your Yamaha Recording Equipment does not work, the batteries may be too weak, so replace them with new ones. Also, make sure you are using the remote within 6 meters and a 60 degree radius. Direct sunlight or lighting (of an inverter type of fluorescent lamp, etc.) may be striking the remote control sensor of the unit, so try changing the position of the unit.
What to do if play does not begin on my Yamaha CDR-D651 Recording Equipment?
If play does not begin on your Yamaha Recording Equipment, the disc may be damaged, so check it carefully and replace it if necessary. There may be moisture on the laser pick-up, so wait 20 to 30 minutes after switching the unit on before trying to play a disc. The disc may have been loaded upside down, so reload it with the label side facing up. The disc might also be dirty, so try cleaning it.
Why can't I play a recorded CD-R or CD-RW disc from my Yamaha CDR-D651 on other players?
If you cannot play back a recorded CD-R or CD-RW disc from your Yamaha Recording Equipment on other CD or DVD players, the CD or DVD players may not be compatible with CD-R or CD-RW discs, so use a CD or DVD player compatible with those disc types. The disc may also not be finalized, so try finalizing the disc.
Why does the sound 'skip' on my Yamaha Recording Equipment?
If the sound from your Yamaha Recording Equipment “skips,” the unit and/or the component being recorded may be subjected to vibration or impact. Relocate the unit(s). Note that this is not possible if the skipping sound is already on the recording due to vibrations or impact that occurred during recording. Also, the disc may be dirty, so try cleaning it.
Why is my TV malfunctioning when I use the Yamaha CDR-D651 Recording Equipment remote?
If the TV functions strangely when using the remote control for your Yamaha Recording Equipment, it may be because the remote control is being used near a TV set with a remote control sensor. Try relocating the unit away from the TV or cover the TV’s remote control sensor.
Why does my Yamaha CDR-D651 Recording Equipment sound 'hum'?
If the sound from your Yamaha Recording Equipment “hums,” there may be improper cable connections. Securely connect the audio cables. If the problem persists, the cables may be defective.
What causes play to be delayed on Yamaha CDR-D651?
If play is delayed or begins at the wrong place on your Yamaha Recording Equipment, the disc may be scratched or damaged. Check the disc carefully and replace it if necessary.
Why is there noise coming from inside my Yamaha Recording Equipment?
If you notice noise from inside of the Yamaha Recording Equipment unit, the disc may be warped. Replace the disc.
Why is recording not possible on my Yamaha CDR-D651?
If recording is not possible on your Yamaha Recording Equipment, there are several potential causes. The disc may be finalized, in which case you should load a recordable CD that has not been finalized yet. For a CD-RW disc, TOC Erase or Disc Erase may be needed. Alternatively, a pre-mastered CD may be loaded, so try loading a recordable CD. Check that the input setting is correct by setting INPUT to the position that reflects the source of the input signal. Also, ensure the output level of the source is set to MAX. There may not be enough blank space left or 99 tracks have already been recorded on the disc, so load a recordable CD. If the power cord was unplugged or there was a power outage during recording, the recorded material may be lost; if the recording of a CD-RW disc is interrupte...
