Mimosa c5c chain 1 undetectable issue

Hi anyone has issue the same with mine?
One of my mimosa c5c has fluctuating chain 1 sometimes undetectable sometimes low power…
and the Stream 2 RX Mcx has no value at all. please anyone can help…

please see attach picture

thank you in advance

Looks like a dead chain to me, I would check connectors and make sure nothing is damaged or water has gotten into them.

Hola, yo tengo el mismo problema pero en el canal 1
pienso que parece un problema del equipo, porque invertí los pigtail y sigue igual.
usted pudo hallar el problema?
