When last did you clean the pick up lens on the console?
Sounds like the pick up lens is not reading the disc, any hard collisions on the console recently? If you have the correct lens cleaner at hand I would advise a cleaning asap, see if this solves the issue.

The someone that told you to try cleaning the lens with a cotton swab (q-tip) was right.
if that doesn't work, check all the cables that go to or are in the pickup assembly.
If all that seems OK, then you very well may need to replace the assembly.

Cd drive doesn't respond, interchange & it says tray error

hello dr rashasala!

looks like you have a optical pick-up (or also called lens or laser) problem.

Use a cd/dvd lens cleaner kit or if that does not work, you will need to take apart the unit, access the lens pickup, and clean the lens directly, using isopropyl alcohol with cotton sticks.

anyway if these all dont help you need to replace pick up with a new one. i recommend original spare parts as those sold on ebay mostly chinese production with low quality and durability.

kind regards

The dvd recorder will not recognize any discs. It attempts to read then states "no disc" or "no read". Can this be repaired or is the laser dead?

Hi! there are many reasons why a dvd is note reading. 1. dirty pick up lens, 2. defective spindle motor, 3. defective ribbon wire, 4. defective pick-up lens and defective mpeg board. but first things first try cleaning your pick-up lens with a cd lens cleaner.

Lost link to my chat session

I am the person you had the chat session with. I have no idea why the chat ended. I can help you thru this posting if you wish to continue.

I had mentioned in the chat that you needed to take the top off the unit, and you said you did that but did not know what to do next.

You need to locate the CD mech, the part that picks up the disc and spins it, and then plays it. That part has a clamp on it, it should be in the back middle of the unit. It has a part inside of it that is called the laser pick up. That laser pick up has a lens on it. You need to clean that lens. The lens on it is small and round and looks like a piece of glass. Use a Q-tip and and put a small amount of windex or rubbing alcohol on the Q-tip, just enough to make it moist. Then just use that to clean the lens of the pick up by putting the Q-tip on the lens and moving in a circular motion until you see that the lens is clean. It should never take more than about 5 or 6 circular swipes on the small lens to clean it. Then after you have done that, wait just a couple of minutes and try to play a disc again. If the disc start to play you are done and cann put the top back on again. If it does not play, let me know what it does and I may be able to help you further. But in most cases, if cleaning the lens doesn't help, then you need it serviced by a technician. There are no other secret fixes that make them work besides cleaning the lens, that the user can do. Any further service it may need will require some electronic troubleshooting skills and the proper tools to do that.
