initialy the GH5 viewfinder (LVF) would not display anything when I looked through it, indicating a possible issue with the power supply or the internal connection to the viewfinder circuit. So i Opened the camera and inspected the flexible ribbon cable connected to the viewfinder PCB.
Identified a potential problem with the FPC connector, which appeared loose and damaged at the pin connection points.But i resolder it.
And i Tested the continuity of key components the power board,even the flex cable by cotinuity.
After that, testing, the device did not power on at all, even after check the ribbon cable and ensuring the battery was functional.i have 3 diffrents.
Currently i'm thinking on check if the power board (DC-in connector) has a short circuit or other internal faults that might have caused the system failure
Does someone can confirm which part i have to test and which component maybe ?
Can anyone confirm which specific components I should test further?
Thank you!
