hi thanks for your answer!
I have cleaned the head with a swab and alcohol. I have tried multiple discs, I have tried different batteries and plugged on AC adaptor. The discs are ARTAC, I'm not sure what a CD disc is in this context.
I have tried to it with and without headphones.
The display screen works well, I can access the whole menu except the the EDIT section (BUSY appears when I try to enter ).
There is constantly rotating disc as you mentioned.
I'm attaching a video that might give you a better idea of noise .
thanks again!
