Raw firmware image for the CV59SH-E32 universal LCD TV board, labelled for a Sony set or panel with a 20 tag, and the file name marks it as tested. The 4.00 MB size matches a 32 Mbit SPI flash chip, the usual capacity on these boards. Strip the extra extension so the programmer software reads it as a BIN file. Write it with a programmer such as a CH341A after saving the current chip contents, and check that the panel resolution suits this configuration.
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.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
