Service archive for the Sony Bravia KDL-46HX925 television, about 67 MB in RAR format. The name gives only the model, so the exact contents are not stated. Such packs usually hold schematics, service manual pages or firmware. Unpack it and check each file against the chassis and board labels on your set. TV repair work with this kind of material includes tracing power supply and backlight faults, checking mainboard signals, and restoring firmware on a memory chip. Back up any chip before you rewrite it.
