If you are not comfortable with hardware flashing or in-circuit programming, consider taking your device to a professional TV/display repair shop. A simple firmware corruption that requires a 50-cent EEPROM programmer can quickly turn into a $50 mistake if you flash the wrong bootloader. Tp.v56.pb826 Software Download
