Totally inoperative | Fuse f1 open and resistor r54 toast (open) | I replaced the fuse and connected it with a series bulb. the fountain began to crackle. I turned off the device and after checking the power supply capacitors, I found only the r54 was toast. In this region, the manμFacturer added glue to secure the power supply's electrolytics. Even though the glue is dry, tsound was probably a current leak. I replaced the resistor and everything went back to normal. As a precaution, I also replaced the following electrolytics that tend to replace over time: e1, e3, e5, e9, e10 and e11. | Técnico Rodrigues |
