Hi, I have a sony genezis MHC-GT55 model audio equipment .. the problem I have is that it turns on well but after a few seconds I appear in the diapley a word .. EJECT and it goes off stays in Istanbul .. I disassemble it and take out the tray of cd and continue with the same .. desolde the protection pin and do the same .. I would like to know if you can help me with this fault

measure all volts of the source

These SONY models sense the mechanical system of the TAPE, if you have wide leagues or the mechanism locked the equipment already turns on the Eject and turns off, I do not know how to obviate that, it is a digital sensing directly from the micro that senses the opticians that detect the movements of the engine of the cassettes, in fact I have had to repair the TAPE to be able to use those models of equipment, Check the cassettes that is there the issue. I hope you solve. Salu2
