Hx8872-f Datasheet Pdf !!hot!! -
This information, while not from a formal datasheet, is critical for troubleshooting a non-functional panel. If you suspect a failed TCON, measuring these points with a multimeter can help isolate the fault. In fact, one repair technician noted that a VCOM voltage reading of around (instead of the expected ~6V ) was a clear indicator of an issue on a board based on the HX8872-F.
The HX8872 series is highly versatile, finding its way into several critical sectors: Automotive
