I bought a program called "inDisc Recovery" that locates lost files and then saves them to your computer.

There is only one thing that you can do as the end-user to try and fix this. Try cleaning the lens on the laser pick-up. Most retail outlets that sell CD or DVD players sell a cleaning disc for about $10 to $15. You put it in the machine and let it run for about 20 to 30 seconds. If the reason your DVD player won't play is because the lens is in need of a cleaning, this will fix it. If the reason is anything else it will not help at all. The most common reason for this failure is a faulty laser pick-up that need to be replaced. This is the most common and usually the most expensive repair because of the cost of the pick-up. It can cost anywhere from $130 all the way up to $200 depending on the labor rates of the shop and how much they mark-up the cost of the pick-up. All shops mark-up the cost of the parts. It is not advisable to do this yourself unless you have some experience with electronics and can do some troubleshooting to verify that the pick-up is indeed bad. It is easy to cause more problems than you started with if not done properly. As I stated above, it is the most common, but it is not the only reason. Other causes of this failure can be as simple as a bad voltage regulator or as difficult as replacing a servo IC. It can also be a memory IC (if it plays CD's but not DVD's), a spindle motor, a bad gear or switch, or one of many other causes. That is why it requires some experience troubleshooting them to nail down the exact cause.

I hope that this information was helpful for you to make a desicion on what to do with it, and if so, a rating of "FixYa!" would be appropriate and very much appreciated. After all, it is the only reward we get for offering people like yourself this free help and information.

Let me know if you have any more questions, I will be happy to offer you whatever help I can. I have over 18 years experience repairing these type of products. I have been repairing DVD players since they came out on the market for sale.

I have a Sony CD/tape player model # HCD-NE3. When trying to read a CD - it says NO DISC. What should I do?


Typically a no disc display indicated dust on the optical unit ( lens ) or failure due to low laser beam emission. For the first case you have to remove the top cover and clean the lens very gently with a ear bud. The the cleaning does not solve your problem you have to replace the optical unit itself. Unless you have experience doing the above i won't recommend it. Replacement will cost you about 15$ plus labor.

My husband had a Sony cd player that he used alot. He passed away 3 yrs. ago and I have not used it till now. I put a cd in and it will play for short while, then stops and the red light in front comes on....


Hello
Long duration of unused condition will make its laser head assembly to be infected by fungus. You haven't used this device since 3 years, and so the possibility is of 90%. If you have a lens cleaning disc, put it into it and play for three or four times. Sometimes this may help you. If not replace its Laser Pickup Unit, with same type and number. OK.

Sony HCD-GNZ77D dvd deck receiver DEST ERROR


if your sound system gives you Desk Error or Desk Read Error, try cleaning it with a lens cleaner, they can be found in many forms in the market. If the problem still insists then your system's lens ( the part which read the optical discs like DVD's CDs etc.) need to be checked by a professional technician, probably would install a new lens on your system. You can comment if you need more clarifications. Best of luck

GETTING MESSAGE NO DISC WHEN THERE ARE 3 DISCS


Plain and simple. The device is broken. I can only say the laser might be dirty.  Perhaps get a laser lens disc cleaner. and check to see if that works. If not you should send it off to an authorized specialist. Or if you are feeling brave take it apart yourself.

Do you know where the solder point on a new laser lens is located that has to be removed?


It's opposite the ridge where the type of lens is scribed (PVR-802W, KHM-430)
It's a silver blob, you'll find it easily enough!

Sony DVD player has a new laser assembly, but won't play discs.


Forbes,
I think you have taken on a great task. There are many steps to setting up the lasers before auto align can work. There are manual settings which need to be done. The manual will be helpful, however there is a knowledge of how to do the initial settings needed in order to get the unit just to recognize there is a disk waiting to be played. That happens in what is the initializing stage. If the settings are incorrect the unit won't even see a disc. I used to own a service center that was authorized by over 70 manufacturers. Laser replacement was never a swap and play thing. Alignment was always critical. And one more thing you should know. If the laser is too hot after you get it playing it will go bad quickly. You need a meter to check that as well. God luck Rob
