Hi frodrigue328,
If you have necessary tools and test instruments, know safety precaution in basic troubleshooting try the steps below to solve your problem.
Assuming that the disc is good.
1.Clean the lens. - Sometimes because of dust the lens can't read any disc. Try clean the lens by soft cotton buds. Be careful while doing this.
2.Check the ribbon - Check the ribbon connected to the lens from the main board for scratch, damage. Once it has an open line then of course the lens can't read the disc. Also try to erase the contact by pencil eraser. If you've done the steps above and the symptoms still there then the next step requires you a little knowledge in soldering technique and reading the ohmmeter.
3.Check the motor - Check the motor that spin the disc with an ohmmeter. You can test it using the ohmmeter (x1) even it is connected on the lens assembly.Good motor - reading should be fairly high and it will spin. Bad motor- reading will drop to low resistance and will not spin.
Hint : 50% of my repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor then replace it with a new one. Before replacing the new motor you have to check the clearance of the disc holder with the old one. The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.
If the above steps didn't cure the problem, high chance that your optical lens was faulty.

If you can't do the job yourself, I would advice you to look for a professional to troubleshoot the symptom.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

hi,
You have to check the laser pickup unit of you dvd player. In your dvd palyer the laser pickup unit is faulty. There are two lasers in DVD players laser unit. One for reading the DVD and the other for reading the CD. In your player the DVD laser is faulty. As it is one module you have to replace the laser pickup unit as a whole. You will get it from any electronic spare part shope near to you. As a whole i mean Normally laser pickup units come with its mechanism like in the picture . May have slight difference with your one. picture is only for reference. Its part number will be written on the bottom side of the laser unit. you have to take the laser unit as sample when you are going to buy the same. If it is reading cds it is sure that the laser pickup is faulty. Its a regular complaint to dvd palyers. To replace the laser pickup you have to remove the cd loader and have to remove connections to it.

1. When an optical drive doesn't read or recognize CD/DVD the unit is in need of replacement. Units can be straight out of the box and fail.
check the connection to the device ( cable) and the power to the unit

I have a philips hts6510 home theatre system and when i put a dvd in to play it says no disc


hi,
Normally a dvd player shows the message NO DISC when,
1. The disc inserted is bad.
2 The lase pickup unit inside the dvd lost its reading intensity, dirty lens or the spindle motor damaged .

In your case the second one happened. the intensity of the laser pickup unit has lost or the spindle motor faulty or there is some dust on its lens. just insert a cleaning cd in it for two or three times. then check again is the DVD is reading or not

if the problem remains then you have to check the motor and the laser pickup unit. the lase pickup unit have two laser emitter and receiver in its inside . one for reading and playing DVDs and the other for CD and MP3. also the spindle motor runs in different speed when u insert dvd and cd.

Open the cover of your dvd player and power it on insert an audio cd and watch is it reading or not also notice the speed of the spindling of the cd. if the audio cd reads and play. then the possible problem is the spindle motor

To conform it remove the audio cd and insert a dvd. watch the rotation of the dvd. if it feel very hard to rotate it then, the spindle motor is damaged. if so replace the spindle motor if it runs more the the speed of than audio cd then the laser pickup unit is faulty. Then u have to replace the laser pickup unit.
if you need any further assistance from me , feel free to contact me through fixya.
ok

Can't read CD but can read DVD


This is not uncommon. I have seen it often. It is a sign that the unit is about to fail, and needs to be replaced.

I don't know where you are, but around where I live, these dual layer DVD RW drives retail for less than 30 dollars. They usually come with software and are not difficult to install.

Beware of ESD, however, whenever you are working on the inside of a pc. ESD (electo static discharge) can destroy the insides of your machine without you knowing it until it's too late.

good luck

I just doesn't load/read CD's.


I had the same problems with my four year Denon DVD-3910 and the only solution to it was to replace the laser unit with a new one.

There are some repair service on EBay that offer new laser units for only about 50 € and are also willing to change the laser unit for an extra charge of just 30 €.

After this replacement your Denon DVD-3910 will work fine again.

DVD Unit not reading


Sounds like the optical eye in the drive is shot, unfortunately replacement is your only option. The machine will still recognize it's there even though it's not working properly.

CD/DVD DRIVE DOES NOT READ PROPERLY


Really the ONLY thing one can do.. is replace the unit with another know good working one.. IE:New. Usually a GOOD CD/DVD will instantly & always work... it will be picked up by windows and then the appropriate "Drivers" installed. As an IDE CD/DVD is "Generic" it generally doesn't require a "Special" Driver, so windows uses it's "Own" driver. Therefore generally if it's showing as OK in Windows, but is NOT going... then, usually, as I said, it is kaput.. for some reason... usually the laser Diode or Quadrant detector...
