What does “U70?” mean on my Panasonic SC-PTX50?
- EElaine RobinsonSep 9, 2025
If your Panasonic Home Theater System displays “U70?”, it indicates an unusual HDMI connection. This could be due to the connected equipment not being HDMI-compatible, using HDMI cables without the HDMI logo, an HDMI cable that is too long, or a damaged HDMI cable.
