Fourth PDF in the TH32A410H schematic series, 6.62 MB with a -4 suffix. All four files in the set share this exact size, so they may be copies of one manual rather than distinct chapters; compare a few pages before assuming different content. Use any PDF reader to follow power rails, standby circuits and the signal path to the panel. Before measuring or replacing parts, confirm the model label and the board numbers inside the set match the document.
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 @datasheets1. Enginerys does not host this file.
