Question about Philips CDR765 2-Disc CD Recorder

2 Answers

No audio The problem I seem to be having is that I plug in all the wires to the back of the unit and the unit does not seem to recognize the audio coming into it. It simply displays "no audio". What can I do. It also won't dub, it just displays "no audio" whenever I hit the record button.

Re: no audio

'no audio' comes up when you use a computer grade cdr disc. Buy some audio use CDrs and it'll be fine. Google for the manual - it explains 'no audio'

If you get no or a distorted, low sound output when playing,it's likelt a failure of the op-amp on the cdr PCB.

My kenwood head cd unit in my car keeps on flashing "protect" i checked all wires in the head unit and will stay ok for a while but it goes back to protect...

Check the speaker in you car which are connected to you head unit. if the speaker or the wire which runs to the speakers have some problem then the head unit will show protect.
Also one more possibility is, the faulty output amplifier IC in the head unit. if the audio out put IC is short or fail then also the unit will show the same. Audio output Ic means the audio amplifier. Check the speaker and wire first. Mainly the wire check is there is any insulation damage in it. if the insulation get damaged possibility to get contact with the metal part of the body of the car then also the protect will appear.

Player will not come back on after about 1 year of good service, only shows a speaker with an x across it, wont come on , take a cd or anything.

You have a shorted speaker wire and the unit is protecting itself from damage. Fastest way to confirm is to disconnect the speakers at the unit. If it powers back up, add 1 speaker at a time back on. it will cut back out when you find the bad wire or shorted speaker. If you still have an issue, post a comment and I can help you further.

Discs to use?

Yes. On Page 9 of the Manual:

"For recording use, special audio discs must be used (for music
only). These Discs bear the logos as shown below. The text
‘DIGITAL AUDIO’ is present!"


"Your CD recorder is able to play:
- All pre-recorded audio CDs.
- All Audio CDR and Audio CDRW."

There is no capacity qualifier mentioned.

Does the unit recognize 80 minute discs?

Any desk CD recorder will only recognize discs labeled "Audio Disc".
That means you cannot use CD-R or CD-RW discs, that are basically data discs. No matter duration, if your 80 minute disc is CD-R or CD-RW, your unit will not recognize it. Good Luck.

I have a 1998 Pioneer head unit to put in my car. the #is 1256237179. Is There anyway to get a diagram to see how to hook it up?

Hi there,

Well you can please follow the below steps -
1. Disconnect your car battery. It is vitally important to your safety that you never work on any type of electronic in your car with the battery still connected, as this puts you at risk for electrocution.
2. Remove the old stereo by taking off all the dashboard panels surrounding your stereo, sliding out your old stereo head unit, and unplugging all the wires that are connected to the head unit. Discard the old stereo.
3. Take your Pioneer car stereo head unit and plug each of the positive wires from your car speakers to the positive terminals on the head unit. Take all of the negative speaker wires and connect them to the negative terminals on the head unit.
4. Attach the stereo's black ground wire to a metal bolt or screw located near where the stereo is mounted in the dash.
5. Connect all of the ignition power wires to your Pioneer stereo.
6. Take the harness connector and plug it into your car stereo. Now plug the antenna into the back of your head unit.
7. Slide the stereo back into the dash, screw it in place, and replace the dashboard pieces you removed earlier.
8. Reconnect your car battery, turn the car on and test out your new Pioneer car stereo. Please post comments for more help or information..........

Good Luck!!

How do I hook my MP3 player to this system?

The MP3 on the front just means you can put a cd that has MP3 files in there and it will play.

RCA CD recorder/player CDRW120

You sure it's recognizing the CDR? And you are using 'consumer audio' cdr? Watch it at all times. If it 'opc fails' after you put a blank in it still shows as a CDR and 0:00 on the display but won't record. It's easy to miss.

Philips cdr 765

I just purchased one from Ebay. It plays fine on both sides. The recorder will recognize CDR's and the display will say recordable media. But, when I attempt to actually record, it won't work. I have another unit exactly like this one and the CD's I have work fine with that unit. I'm guessing this unit's recorder is bad? Any suggestions? Thanks.
