System dependent (Common variants: 75V / 560mA, 2055B 600mA)
Replacing only the motherboard is significantly more economical than purchasing a new 4K television.
This is caused by mismatched LVDS/V-by-One mapping parameters between the mainboard and the panel T-Con module. Open the Factory Menu , locate the Panel Config settings, and toggle the LVDS TI Mode , Bit Depth (8-bit vs 10-bit), or JEIDA/VESA standard options to correct the signal timing. Summary of Advantages
| Affected Component | Typical Failure Symptoms | | :--- | :--- | | | Boot loop or stuck at logo. The 3.3V regulator may become overloaded and overheat, indicating a short circuit within the chip. | | 3.3V Voltage Regulator (UD3) | Overheating and outputting an unstable voltage (~3.1V). Caused by a downstream short (often the main chip). | | eMMC Flash Memory | Software corruption, boot failure, or erratic behavior. The eMMC chip's lifespan is limited, and its failure is a common cause of software issues. |
If your screen displays inverted colors, upside-down images, or a "ghostly" double image after installation, you must calibrate the firmware settings via the factory service menu. Power the TV on using the bundled remote control. Press the or Source key on the remote.
