I have a dcd 1650 and it won't read discs, but sometimes it does, I have checked and cleaned lens


A Laser Lens malfunction will cause this to happen and is a common problem. This can be fixed at home if a new Laser Lens or Laser Lens w/ transport can be found for your unit. I used ebay to purchase a new Laser Lens for my Denon DVD 5900. The part is also sometimes available from parts stores like Parts Express for a premium, $100+ Parts Express vs $17 ebay in my case. I would recommend purchasing a FACTORY SERVICE MANUAL from an online vendor. The manual will cost between $10 - $20 and is downloadable. The installation is very straight forward. The part that might not be clear would be the grounding shorts on the new Laser Lens. THE NEW LENS COMES SHORTED AND AFTER THE PART IS INSTALLED IN THE PLAYER THE GROUND SHORTS MUST BE UNSOLDERD FOR IT TO WORK CORECTLY. The part comes this way to protect the Laser from static shock damage.
The repair on a Denon DVD 5900 cost $30 and took about an hour to complete.

I am unable to play DVD's and receive error message HD7. How can I fix this? I own Panasonic DVD-RV32 player.


I think you mean H07 - this means the traverse unit (which contains the spindle motor and the laser in one assembly) has failed. The spindle motor is the most likely problem; unfortunately this is not repairable at consumer level, it would need to go to an authorised service workshop where the whole unit would be replaced in the player, which would include a brand new laser. The other snag is the cost - a new traverse unit can cost around $200 + labour (including alignment and firmware upgrades)!

Save yourself the agony, and simply replace the whole player - cheaper than repairs. The RV32 was not Panasonic's best DVD player model.

Please help me to solve the problem with error H03 of DVD-LX8. Thanks a lot.


These H errors may refer to either the laser pickup or spindle motor or both. In this case, H03 and H07 are both spindle motor related. The only trouble is that this part is not serviceable, you cannot dissect it to clean it etc., so it must be replaced (most models I have dealt with have the laser/spindle motor as one part - known as a traverse unit) along with the laser which is also part of this device.

If you cannot hear any discs spinning when you load them, and you should be able to, then the motor within the traverse unit has given out. This can be expensive to replace unfortunately. I advise that you probably take the player to a repair shop - preferably an authorised Panasonic agent, get a free quote and make a decision afterwards as to what you wish to do.

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.

Player does not recognize or play CDs


Thats how some manufacturers sell there replacement parts as they come into the country assembled. it cost let to import but more for us. i once needed a spindle motor for a unit, no replacement except the manufacturer part. Had to buy entire laser assy and thats what they bare selling you too. If you already tryed to manualy clean the lens, look on the side of the laser pick-up. it might be made by sony or a popular manufacturer go by the number printed on the label on the side or bottom of the laser assy unit itself. Good Luck
