ZIP archive of 2.27 MB for the Philips 40PFL4650 LCD television. Only the model code is given, so board revision, flash type and firmware version remain unknown until the archive is unpacked. Such files usually provide memory dumps for restoring a set that will not leave standby or keeps restarting. Identify the memory chip and its capacity, read and save its current contents with an SPI or I2C programmer, then write the image and compare the read-back against the file before reassembling the TV.
