Universal-TV-Service-Remote

📺 TV Master Service Remote

🌟 Overview

TV Master Service Remote is a powerful, open-source Android tool tailored for electronics repair technicians, TV engineers, and hobbyists.

Retail television remotes intentionally omit discrete factory and service keys. When a technician needs to configure panel settings, fix flipped/mirror displays, adjust LVDS mapping, or troubleshoot firmware on consumer or universal boards, dedicated physical service remotes are often expensive or unavailable.

This application transforms any Android smartphone equipped with an Infrared (IR) Blaster into an all-in-one universal service tool capable of transmitting discrete service codes, firing automated macro sequences, looking up universal Chinese chassis codes, and transmitting raw Pronto Hex strings.

⚡ Key Features

🔑 Discrete Service Mode Keys: Direct transmission of factory-level keys unavailable on consumer remotes:
- LG: IN-START (0x20DFDF20), EZ-ADJUST (0x20DFFF00), IN-STOP (0x20DF55AA), POWER-ONLY (0x20DFFE01).
- Samsung: FACTORY (Device 7.7, Func 59), 3SPEED (Device 7.7, Func 60) for unlocking region/LocalSet options.
- Sony: SERVICE discrete sequence & test mode toggles.
🤖 Automated Factory Menu Sequences (Macros): One-tap automated execution with microsecond-precise timings:
- Menu + 1 1 4 7 (Most common for Chinese boards)
- Input / Source + 2 5 8 0 (CVTE / Realtek / MStar)
- Input + 2 0 8 / 2 0 0 8
- Input + 8 1 5 / Menu + 8 1 5
- Menu + 8 2 0 2 / Menu + 0 0 0 0
- Samsung Standby Sequence: [MUTE] → [1] → [8] → [2] → [POWER]
- Sony Standby Sequence: [DISPLAY] → [5] → [VOL+] → [POWER]
🎛️ Universal Chassis & Motherboard Database: Built-in lookup library for universal boards:
- TP.MS338.PC821, T.VST59.031, T.V56.03, TP.HV320.PB801, SKR.03, T.R83.03
- CV338H-A42, CV182L, CV56BH, CVMV26L, TP.VST59.PB819, VS.TP53U61.2, and more.
📡 Bit-Accurate IR Modulation Engine:
- NEC Protocol: 32-bit standard & extended with carrier modulation at 38 kHz.
- Sony SIRC Protocol: 12-bit, 15-bit, and 20-bit with carrier modulation at 40 kHz.
- Pronto Hex Converter: Instant parsing and translation of raw 4-digit Pronto Hex arrays into alternating Mark/Space timings.
🎮 Tactile D-Pad & Service Controls: Modern dark-themed UI built with Jetpack Compose and Material 3, featuring haptic feedback for precise navigation inside factory menus.
🛠️ Custom Hex / Discrete Code Sender: Test and send custom IR codes on the fly.
🌐 Interactive Web Preview: Includes a standalone, offline-ready web version under /web_preview for rapid testing and demonstrations in any modern web browser.

📱 Hardware Requirements

To transmit physical IR signals, you will need:

An Android smartphone with a built-in Infrared Emitter (IR Blaster):
- Supported brands: Xiaomi, Redmi, Poco (e.g., Redmi Note series, Poco F/X series), select Huawei/Honor, and select older Samsung Galaxy / HTC devices.
Alternative for non-IR phones:
- Supports external 3.5mm headphone jack or USB-C IR transmitter dongles.

[!NOTE] Even on devices without an IR blaster, the app opens seamlessly, allowing technicians to look up motherboard combinations, read technician guides, and view code references.

⚠️ Technician Disclaimer

[!WARNING] Accessing television service menus enables low-level modification of EEPROM, panel timing parameters, LVDS bit depth, and backlight voltages. Incorrect adjustments can cause panel blanking or boot loops. Always record initial values before modifying any factory options. Use the IN-STOP function with extreme caution as it performs an irreversible NVRAM wipe.
