Hello,
I have a T+A 1220R that always displays "no disc."
It doesn't even try to spin.
I can see the lens 2-3 times, but I can't see any red light.
I replaced the laser unit with a "new" one, but the error remains the same.
I then measured the LDON signal on the SAA7372, but it stays permanently low. That can't be normal, can it?
Unfortunately, the manufacturer doesn't provide any documentation about the device.
But maybe someone here can help.
Regards
Mario

Hi. Some weeks ago I repaired a T+A DVD, I don't remember the model, with the same symptoms. The problem was the switched power supply capacitors, a typical chinese switched power supply with Teapo brand capacitors.
Solution: Replace all.
