#177047 - see it carefully Responding to: ???'s previous message |
You must see damaged equipment carefully to understand where is problem.
For example i saw Ethernet cards , used for PC to WAN connection with cable 5..10 meters long ,which going OUT of home - from PC to nearest WAN optical converter. On these boards i noted small capacitors connected between RJ connector and PC-ground. These capacitors were damaged. And because cards are cheap - nobody tryed to understand - just replaced. regards |
