Cd/dvd player noise

When a CD or DVD is playing a grinding noise seems to come from the back of the unit. It does not affect the video or audio playing capability. However the 'noise' is worrisome. Any suggestions?

Re: cd/dvd player noise

Something could have been misalligne or not sitting properly in the DVD rom...if the grinding sound is mechanical. The only possible way to cure this is to open the DVD ROM and service its mechanism. Observe DISC that is played if there's any sign of scratches...sign tells that its touching or rubbing something.
Good Luck.

If you really like the unit (disregarding the DVD player issues), maybe you could buy a GOOD stand-alone DVD or BluRay player and be ready for an upgrade in the electronics when the bug bites.

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

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.

My home theater system plays cds but will not play dvds, what can I do to fix it, makes a scratching noise when i put dvds in it, but plays fine with a cd.

There is something wrong with the DVD drive assembly inside. If you're brave, take it apart and check on what is making the noise. Also, try using a q-tip to clean the laser head if it's accessible.

If that doesn't help, it's time for a new DVD player.

This is why I always recommend people buy a home theater system without a DVD player built in. The DVD player is the weakest link, and stand alone DVD players can be purchased for as little as $25 depending on if you want upconversion or not.

If you cannot get the DVD player working in your surround system, just replace it with a stand alone DVD player, if you can, check to make sure there are audio inputs on the back of the receiver. If there are no audio inputs on the receiver, you will have to get the entire surround system replaced. If so, purchase a separate DVD player and surround system.

No voice sound through speaker with DVD system, only music?

first check the settings on the audio menu of the dvd player. make sur it is set to 5.1 (if available) otherwise set it to stereo and your system should decode it.
assuming the second step is okay : as other dvd you play seem to work) it still may be that your unit is decoding stereo inputs just fine and 5.1 is not working properly....
so if adjusting audio settings in dvd play back menu dont work,
check that the cables to the satellite speakers are connected correctly and all plugged in soundly ( voice is high frequency,- coming from satellites - the garbled noises you hear are the base ( low freq) elements of voice which are coming from the bass box ( that the X.1 part of 5.1) and so that is obviously working. ,
