Summary

RS-232C control spec for Sharp LC-60E77UN and LC-65E77UM LCD TVs (LCE77 series). PC connects to TV via cross-type RS-232C cable; TV accepts 8-ASCII command frames terminated by CR (0x0D) and replies with OK or ERR.

# UNRESOLVED: The RS-232C section documents no command interlocks or power-on sequencing requirements.

Notes

  • Frame format: C1 C2 C3 C4 P1 P2 P3 P4 = 8 ASCII codes + CR (0x0D). Parameter is 4 chars left-aligned, padded with spaces (underscores in the table are notation for ASCII spaces, never literal transmitted underscores).

  • Send commands one at a time; wait for OK response before next command.

  • Out-of-range parameter returns ERR.

  • The manual illustrates generic query parameters ? and ????, but says only that some commands accept them. It does not identify which opcodes support querying. No per-opcode query actions are asserted; query applicability and response formats remain UNRESOLVED.

  • Underscore _ in parameter column = enter a space. Asterisk * = enter value in range indicated in CONTROL CONTENTS.

  • Commands not in table not guaranteed to operate.

  • Evidence: Sharp LC-60E77UN / LC-65E77UM Operation Manual, printed page 41 (PDF page 43), RS-232C Port Specifications. Official source: https://files.sharpusa.com/Downloads/ForHome/HomeEntertainment/LCDTVs/Manuals/tel_man_LC60E77UN_65E77UM.pdf

  • Command strings above use the manufacturer's table notation: replace */x with the documented numeric parameter, left-align within the four-character field, pad the remainder with ASCII spaces, then append CR. The opcode is always four ASCII characters; the full transmitted frame is nine bytes including CR. Do not transmit the table placeholders literally.

  • No hardware validation has been performed. Compatibility is limited to the two model names printed in this manual.
