Due to the glare, it's difficult to make anything out in the photos, but what I can make out in the soldering doesn't appear to be anything out of the ordinary.auron wrote: ↑Wed Mar 31, 2021 3:07 amOh no, i did a photo of the opened up device , that soldering is not too bad maybe? see the attached pics....planetearth wrote: ↑Wed Mar 31, 2021 12:13 amIf something basically exploded inside your 1820m and got it hot enough to melt the solder, you can't fix the 1820m. The only way to "solve" this issue is to replace the interface.auron wrote: ↑Tue Mar 30, 2021 7:41 pmOh my, yesterday my old EMU1820m did a loud noise like you would hear a radio turned on and no channel selected. Then i openend the breakout box and saw that all the soldering is completely messed up, like a little river going here and there. Some of you guys have any idea, how to solve this mess?
I'm sure that's not what you wanted to hear, but if "all the soldering is completely messed up, like a little river going here and there", then you really can't fix it. And if the solder really did melt, you can be sure some of the components burned up, too.
Considering you said that the interface "did a loud noise like you would hear a radio turned on and no channel selected", I don't think what's on the soldering joints is the issue. It appears that's been there for some time. You can clean the PCB, but my guess is a capacitor finally died. The ones near the power supply usually fail first. Look for bulging and/or scorch marks on the tops, sides, bottoms, or even underneath.
