"Q5481" appears to refer to a specific chassis series or a service code for a range of Philips TVs (often from the 6xxx or 7xxx series, e.g., 65PUS7354, 55PUS7304, etc.), rather than a single model number. The upgrade process is identical across this chassis family.

The platform was a cornerstone for high-end Philips TVs launched around 2009 and 2010. These televisions, which included series like the PFL7664, PFL8404, PFL9664, and others, were highly advanced for their time, featuring LED lighting, Net TV (Philips' early smart platform), and exceptional picture processing.
