Question about Sony RDR-GX300 DVD Recorder
Its power board had got damaged. It ony supplies 5VDC to the board, which in turn energises the system control and display. There is 4 more voltages out from it is missing. You have to findi out it, and reason for its failure. Actually the swithcing process in the power supply board is OK. But without the above said missed voltages, there will be no motor voltages and mainboard chroma and decoder voltages. The system is very complicated in circuit nature, so without any previous expeience, never attmpt to reapir it. If you are well aware in digital electronics, you can do this. A high quality digital multimeter and a concept of soldering are also needed. I've given you the fault advice according to your post. Determine what should do. OK.
