Sony archive for the KLV-22BX320 LCD TV on the AZ2EK chassis, 1.49 MB in RAR form. KLV is the model prefix Sony uses in some Asian markets, so the contents likely match the KDL version closely. The name does not say if it holds a service manual, schematics or firmware, so check after extracting. Service data like this is used to follow power rails, check the main board and panel connections and locate parts. Confirm the chassis code and board numbers in the set before applying it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @gunvantrathore. Enginerys does not host this file.
