Hello,
I have a NAD T-513 that always display DISC Err, no matter what kind of CD I use.
I change the optical laser pickup, it was only 20$, I had nothing to lose, but it did not solve the problem !
My question is:
On a good working CD player, is the RPM always constant, because on mine, it goes up then down, up then down repeatedly ???
I check the VCC pins of the Motor Drive IC (LA6560) and +8V is present. But one thing I notice, this IC gets hot really fast ???
Do you think LA6560 is bad or the spindle motor ??
Thank you !
