Is there a Stack community that could help me with this?
While various people will redirect you towards Electrical Engineering (electronics.stackexchange.com), you'll note the following in their help page:
This site is for electronics and electrical engineering professionals, students, and enthusiasts. We ask and answer questions about electrical and electronics engineering topics, which include electronics, physical computing, and those working with microcontrollers, Arduinos and embedded systems. We feel the best Electronics Design questions have a schematic, links to pertinent datasheets or some source code in them, but if your question generally covers …
- a specific electronics design problem
- the theory and simulation of electromagnetic forces
- a communication scheme
- the writing of firmware for bare-metal or RTOS applications
You have neither.
and it is not about …
- a shopping or buying recommendation
- consumer electronics such as media players, cell phones or smart phones, except when designing these products or modifying their electronics for other uses
I see no valid reason for people to keep recommending Electronics for general consumer electronics repair questions.
Some repair questions are on-topic, but that applies to faulty circuits. When you're somewhat adept at electronics and have an understanding of what's going on, it's possible to phrase it as a perfectly valid question about the electronics involved. Parts identification, circuit board routing and possible causes when measuring voltages across the boards can be on-topic. However, that's much more specific than the example you ask about.
