Before desoldering, ensure you discharge all capacitors and disconnect the power supply. Refer to the image below for the exact chip location. [Click to zoom](https://tvtech.online/wp-content/uploads/2026/10/skr-03-SPI-25Q32.avif) ## Known Issues – Four-Star M22 (SKR.03) The following faults have been documented and confirmed to originate from **corrupted or failed SPI 25Q32 memory** on the SKR.03 mainboard. Reflashing with the verified dump below resolves these issues. - TV stuck in endless boot loop – logo appears then restarts continuously - No display output – backlight powers on but screen remains completely black - Frozen or stuck on the Four-Star logo during startup - HDMI and AV input ports not detected or not switching - Audio plays normally but no picture displayed on screen - Channel scan fails or saved channels lost after every power cycle - Remote control unresponsive – no IR signal processing - OSD menu corrupted, garbled text, or missing menu options - TV powers off automatically after 2-3 seconds of startup - Firmware update via USB fails or causes brick - Panel displays vertical or horizontal lines due to corrupted timing data ## Diagnostic and Repair Protocol ### Required Tools and Equipment Before beginning the repair, ensure you have the following tools ready: **SP8 programmer**, SOP8 test clip or socket adapter, soldering station (for chip removal if needed), thermal paste, antistatic wrist strap, and a computer with SP8 programming software installed. ### Step-by-Step Flashing Procedure 1. **Power down completely** – Disconnect the TV from mains power. Wait at least 30 seconds for capacitors to discharge fully before opening the casing. 2. **Access the mainboard** – Remove the back panel screws and carefully separate the rear casing. Identify the SKR.03 mainboard and locate the 25Q32 SPI chip. 3. **Connect the SP8 programmer** – Attach the SOP8 clip directly to the 25Q32 chip on-board, or desolder the chip and place it on the programmer socket. Ensure correct pin orientation (pin 1 indicator dot). 4. **Backup existing firmware** – Always read and save the current chip contents before writing. Store the backup file with the TV model name and date for future reference. 5. **Erase the SPI chip** – Perform a full chip erase using the SP8 software. Verify the erase was successful by confirming all bytes read as 0xFF. 6. **Write the firmware dump** – Load the downloaded BIN file into the SP8 software. Select chip model W25Q32 and execute the write operation. Do not interrupt the process. 7. **Verify the written data** – After writing, perform a verify operation to compare the chip contents against the source BIN file. Ensure 100% match with zero errors. 8. **Reinstall the chip** – If the chip was desoldered, carefully resolder it back to the PCB. Check for cold joints or solder bridges under magnification. 9. **Reassemble and test** – Reconnect all ribbon cables and connectors. Power on the TV and verify that it boots normally, displays picture, responds to remote, and all inputs function correctly. ## Video Repair Guide Watch the complete walkthrough for diagnosing and flashing the **SKR.03 mainboard SPI memory** on the Four-Star M22.
