| Defective capacitors, resistors, diodes, I.C.s, cracked P.C. boards, way wrong supply voltage(s), foreign metallic objects & solder splashes causing a short are all I can think of unless you want to start talking Gremlins, etc. | |

|
| Hi
The TECHRON amplifier series 7700 shows OVERLOAD fault (LED is ON). I followed all the procedures given in the manual and tested the output transistors, dirver transistors and predirver transistors but I didn't find any faulty transistor. I am unable to find the reason for the error. Does anyone know what may cause this fault and what further check I can do to fix this fault. Thanks in advance |
