ICOM A2 lan problem
Hello,
Im trying to repair one of my A2 interfaces. It acts like theres no power. No led blinks or anything. I controled all the solderings and routes. After +12V input pin there is a diode and a coil. When I put +12 after the coil leds starts blinking so Im suspecting one of those two is damaged. I would like to change it but there is no info on the parts. Does anybody have any info about D1 and L2 coil? Also interesting that L3 is empty... Thank you |

RE: ICOM A2 lan problem
Fuse changed and icom starts working. Anyway I have another issue, system led starts blinking and when I connect lan cable also lan led starts blinking. But interface was not found in itool radar. So I disconnected lan and connected back and lan led now stays off. No matter what Ive tried only system led is blinking. Its strange because before the fuse blown up it worked all good and now I just changed the fuse
 Any suggestions what could be wrong? Thanks |
