A Touch-Panel Contact Can Fail Before the Frame Is Installed

What the evidence preview establishes

The spot-silver contact on the failed panel showed poor registration, oxidation, and weak adhesion to the underlying silver thick-film pad. These conditions provide a plausible contact-level explanation for the reported position errors; the report did not isolate one as the sole cause.

Why this case matters

For an intermittent or position-dependent touch-panel response, inspect contact registration, silver condition, and interface adhesion together. A mechanical frame change cannot by itself repair a defective deposited contact.
