ZIP archive of 4.44 MB for the Philips 32PFL4737 television, with only the model in the name. It shares its size with the 32PFL4537 package, suggesting a common chassis, but that must be checked against the board rather than assumed. The contents are probably a full main board flash image used to revive dead or looping sets. Read the board code on your PCB, compare chip capacity with the image size, and store an original backup with your programmer before you erase or write.
