Files for the LG 32LB550A LED television in a 4.61 MB RAR archive. Apart from the model name, nothing about the contents is stated, so open it to see whether a flash dump, a service manual or both are included. Such packages are typically used to reprogram the main board memory when the set boots badly. They also help to trace the power and panel circuits when no picture is shown. Make sure the board numbers inside your unit match, and save the original flash data before programming.
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 @hashmielecom. Enginerys does not host this file.
