Hi welcome to just answer
How long have you owned the system. When was the last time it worked?
Have you tried lens cleaner?
Lens cleaner will clean the system laser and can be fist trial here.
You can find laser cleaner at your local Walmart or radio shack
I will suggest going this route first,
Yes, please let me know the result
Thanks for the update. Based on your explanation, the system has a laser failure. It is not easy to perform the test as you will need a power meter to read the lens power.
I am not sure if you would like to get the system diagnosed on one of your local electronics repair shop as I am limited here online.
At this point, I would probably evaluate repair and replacement costs.
