hello
It happens that in my house there is a SONY HCD DX20 equipment, when I made it work in the cassette mode (tape A / B) it worked when I wanted, that is, it cost a lot for the cassettes to work, I opened it to see what was inside, I blew (it was a lot of dust) and I rearmed it, then I switched it on and when I turned it on it said something like "EJECT" on the screen, I turned it on again and automatically TAPE was selected and turned off, but sometimes pressing Tune the radio worked, I changed it to TAPE and it turned off, what can it be?
I need help (it's from my grandfather and they will give me a good challenge hehe)
