Hello Adeel_Ahmed, thank you for reaching out to the Samsung Community. Regarding your question about the One Connect Box for the QN55LS03TAFXZA model, this specific model number is not a US-region model; it is primarily associated with the Canadian and Caribbean support. Because our support tools are tailored to US-specific hardware, our information on this exact inquiry is limited. Unfortunately, I was not able to locate this specific TV in our system. However, I can help point you in the right direction to locate this information. If you open the user manual in the link and perform a word search, you should be able to locate the proper One Connect Box for your Frame TV.
