When I try to listen to the cd's, it won't play them. It tries to acknowledge them but the player won't play them


CD players commonly will not recognize some types of CD, eg MP3 recordings, or maybe CD-RW recordings.

However if this is happening with CDs that would previously play OK, then it could be

- scratched or dirty CD surface
- contaminated laser lens in the player
- laser lens has become misaligned

The last 2 need a service technician, but it may be cheaper to buy a new player.

My Philips soundbar will not play DVDs but will play CDs. I have upgraded with latest software


Hi,

I don't think this is a software upgrade issue, but rather a laser problem.

how long have you been using this player? I suspect the laser (lens) of the player. I think the laser (lens) is weak that's why it cannot read data/files on DVD discs.

To confirm if actually its a laser problem, insert an Audio CD into the player and see if will play. If it plays, then obviously, your laser (lens) is weak. But if it doesn't play Audio CD, then it might still be the laser (lens) or a mechanism problem.

Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.

If non of the above solves the problem, then know that you need to replace the laser to a brand new one.

To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.

Once this us done, your player will play all DVD discs again.

Good luck.

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

The cd player does not recognize when a cd is in it. I keeps on saying''no disc''


HELLO
I think the problem here lies with the laser/optical block. Let's try the obvious first. Has the lens ever been cleaned in the time you have had the machine? It may need cleaning and the best way is with a cotton bud and some isopropyl alcohol. You'll have to take the cover off the machine to do this and I ALWAYS say that if you are not confident to this yourself - get someone who is.
Wet the cotton bud (not too much) get rid of any excess. Gently clean the lens using a circular motion then by using the dry end of the cotton bud gently dry it off. Now, if this does not work you may have to consider the possibility the laser is defective and the only cure is to have the laser replaced. BUT BE ADVISED. A laser replacement will not be cheap and I would say if your player is 10 years old or more then it will be just as cost effective to buy a new CD player.
GOOD LUCK!

My one-year old Marantz CD5001 CD player


these models use the 12.1 philips laser mechanism and it is a very common problem for failing to read discs.
various technics / marantz / philips / cyrus cd players etc also use it and are plagued with the same fault.
it's a 90% chance the laser is dead!
philips realised the unreliability of this laser and uprated it to the identical looking VAM-12.
do not dismiss the spindle motor as these also fail quite alot on this mechanism.

hope this helps.

CDR is not working


have a look on ebay for a cheap working donor recorder as spares are very expensive and very hard to get hold of.
i'm guessing your recorder either doesn't read discs, or it won't eject? which is very common and means either the servo board is faulty or the laser.

The following recorders i know off hand for a donor mechanism are:

MARANTZ DR-6050
PHILIPS CDR-775
PHILIPS CDR-770

if it proves to be just a faulty laser, all 3 of the above have the same laser unit.
if it proves to be a faulty servo board, all 3 have the same servo boards except if you fit one out of a philips model it will show 'PHILIPS CD RECORDER' on the display at power up but will still work nontheless.
obviously if a marantz is found it will show 'MARANTZ CD RECORDER' as normal.

hope this helps.

Philips dvp 3020


This is usually caused by a faulty laser.

Most DVDs have two lasers. One for DVD & one for CD.

Sounds like the CD laser has failed.

Problems with playing discs


There are several causes for this problem.

1) Faulty DVD drive. Most drives have a dual laser, one for CD, and one for DVD. Check the player with both CD, and DVD. If it reads one and not the other, then it is most certainly a faulty laser. The laser assembly or whole mechanism will need changing.

2) Dirty or dusty lens. If the unit is kept in a dust environment, dust and dirt can be drawn into the machine by the fan. Try using a DVD lens cleaner. If this doesn't work try a CD lens cleaner. (Dual laser - see 1))

3) Condensation. Condensation can build up on the laser lens if the unit is kept in a humid environment. Also, this can be caused by a cold environment. In this case, condensation forms as the unit warms up. In either case, leave the unit in a warm dry environment for an hour.
