HDMI port damage from cable strain
Why it happens here
Wall-mounted TVs in Klein and Champions homes put the HDMI port at a bad angle. When a cable gets pulled sideways, the port takes the full force and the pins bend or break. It is the single most common Spring repair we handle.
Our approach
We replace the port with a reballed unit on a BGA rework station and verify all 19 pins with a multimeter. We also recommend a right-angle adapter so the next cable pull does not repeat the damage.
