Good day to all! I have a Yamana DX21. Black squares on the screen when turned on. After replacing all the polar capacitors, all the buttons, quartz resonators and setting the voltage according to the parameters on the power supply, inscriptions began to appear after the squares, understandable and not understandable for me. The buttons seem to respond, there is sound, then no sound. And as a result, everything goes wrong, and everything disappears. Firmware version v1.6 10-oct-85. I think you need to roll back to factory settings, but I don't know how to do this step by step.
