Hello.
I have problem with several K8058. Red led working properly but remote dont switch K8056. Every part are solder in right place and i dont find any shortcuts. When i desolder C4 capacitor remote work ok ;/.
What is wrong?
This problem has not been reported before.
Make sure all caps have correct values and that they are at the correct location.
If it works fine with C4 removed, we see no reason to return the kit for inspection/repair
