Question about DVD & Blu-Ray Players
I posted this awhile ago, but I think it may help you:
You can try a cleaning disk, however it has been my experience that the cleaning disk will not help, but it is a good place to start from. More then likely it is a problem with the laser pickup photo-transistor, these often malfunction causing this problem. I would suggest if you are going to try to repair this yourself, you will need a multimeter, a laser meter, and a schematic. The first step is to measure the laser energy leaving the laser diode and see if it matches the specifications in the schematic, if it does not, check the bias voltage with the multimeter, this is to determine if the problem is the bias voltage or the diode itself. If the diode is bad replace it. if the diode is good then the pickup becomes suspect. Using the multimeter measure the bias voltage on the photo-transistor with and without the presence of the laser light from the diode. This will tell you if the photo-transistor is good or bad, if the transistor is bad replace it , if it is good check the components that make up the biasing circuitry.
Now This test will produce a test of go or no-go on the laser diode and the photo-transistor. One of these components or their related biasing circuitry is either bad or about to go bad, by testing the voltages and laser light levels you should be able to determine which one or if both have a problem.
Remember, at least try the cleaning disk first.
I hope this helps,

The microprocessor or memory componets on the player isnt functioning asits supposed too. This is rather troubling and there isnt any easy fixes possible.. My suggestion is seeing as its new return it and get a replacement. Chances are it will fail very soon.

dvd players are finiky things they do not like burnt dvd's at all and some will just lock up computers on the other hand can handel those because burnt dvd's are in a coding format that computers can read much easier than a dvd player your best bet is to just buy the dvd non burned and see if that fixes it. good luck and
If you ever need anymore help with electronics questions pleases dont hesitate to ask me at firstname.lastname@example.org
thanks and good luck
