Question about Philips CDR770 CD Recorder

1 Answer

No disk error

My CD-R Phillips will not reconize any CD-R at the moment I get a no disk message right away . I will buy a cd lens cleaner from radio shack to see if this helps. Hopefully the lens is just dirty.

Cd keeps skeeping

You can try to clean it with a soft cloth. I would check the disk for scratches. If that doesn't work, you can try it in a different player. If it works in a different player, the other player needs cleaned or replaced. It is possible the disk is damaged beyond repair.

DIN UNLOCK on the display

The CD isn't reading the disk, so it reports "blank disk". It could be as simple as the CD laser lens having dust or lint on it, in which case you can use a CD cleaner disk (available at Walmart or Radio Shack, Best Buy, etc.). If that doesn't help, the second most common problem is that the laser lens is out of adjustment, and not focusing properly, thus not reading the CD. This can happen with slight wearing of mechanical parts, or any change in the detection circuity (aging of capacitors, etc.) This can be corrected, but it entails taking the unit apart and adjusting the CD lens on a trial and error basis (adjusting, then trying, until you get it right). Here's a web blog on the procedure, and it will clue you in on what you can try. If you don't feel like tackling it yourself, of course, you will have to have the unit serviced. Get an estimate first, since it's also possible that they will just replace parts, or possibly a circuit board, in the event that adjustment of the lens doesn't solve the problem. Here's the blog:
Good luck, and hope this helps!

When your CD does not read any disk, and returns error, that is usually because of a problem with the optical laser lens that is dirty, faulty or opaque, or a faulty spindle motor unit.

If it is a lens problem, then you will hear disk spinning, whirring and clicking, but the TOC (table of content track at start of CD/DVD will not be read, therefore the error.

Whe this problem is starting you may be able to read only few CD, DVD. After more prolonged usage , the unit will start losing the rest of functions, and ends up not reading anything at all, and returning error.

If instead there is no noise, and disk does not spin at all , then there is a faulty motor, or the motor micro-switch is bad. This situation is far less common than the lens problem.

Try first using a CD/DVD cleaner disk to clean the lens. If that does not work you will need to disassemble the player , and clean lens directly with q tips and isopropyl alcohol, or to replace the lens, or the whole drive unit.

New jazz cd not reconized by player . It says no disk present .

Your laser lens is probably dirty, try a laser lens cleaner if that doesn't work, unplug the unit and take the outer casing off and manually clean the laser with some alcohol and a dry cotton cloth, would also be a good time( see that you have it apart already) to lubricate the moving components with some Vaseline.
Hope this helps with your problem.

No disk

When you get no disk error, that is because of a problem with the optical laser lens that is dirty, faulty or opaque, and will start operating on certain disks better than others. Often the problem get worse in time.
