4. Analysis
During fixing my 7th screen, I made some analysis for diagnosis purpose. It should be quite helpful so I'm sharing them here.
I created these when trying to understand the circuit. Major traces were mapped out and might be helpful for repairs.
I'm sorry that I can't append the original PSD file since it's over 100MB.
These two files are lined up so you can overlay them over each other and toggle the layer for continuity.
