Hello, my amplifier Teac AG-V3020 has power problem, most of the time I’m not able to power it on, even if sometimes it goes ON. Any idea about the reason?

Yes, but is not easy to detect which elements are involved switching from stand-by status to power-on status

Problem solved. Transistor Q901 in front PCB (so hard to reach) was defective, its HFE value was one third of nominal.
Now everything is working good.
