None.
⚠ Safety & Operating Precautions
Firmware binaries are compiled specifically for the processor and pinout on the mainboard, not the exterior plastic branding.
Understanding the difference between the TV model number and the mainboard part number is essential for successful firmware recovery and board replacement.
- TV Model Number: Found on the external back sticker (e.g.,
Onida 43UIB1,TCL 55C645). This designation represents the brand's commercial packaging, chassis design, and marketing tier. - Mainboard Number: Screen-printed directly on the circuit board (e.g.,
TP_HV553_PB801,MSD6A628-T4C1). Multiple TV brands regularly license the identical mainboard design from ODM manufacturers like CVTE or Skyworth.
When troubleshooting bootloop and stuck-on-logo issues, technician-grade firmware matching is always grounded in the motherboard architecture.
