Diagnostic & Repair Protocol
- Visual Inspection
Examine the P50-3663STV5.1 main board for burnt components, bulged capacitors, cold solder joints, and physical damage. Check the 25Q64 SPI Flash IC for cracks or lifted pins. - Power Supply Verification
Measure standby voltage (3.3V / 5V) at the main board connector. Verify 12V and 24V rails are present on command. Confirm stable voltage before proceeding to firmware. - Backlight Test
Use a backlight tester to verify LED strip integrity. If backlight is faulty, repair or replace LED strips before flashing firmware — a common misdiagnosis pitfall. - SPI Flash Backup (Critical)
Using RT809H programmer, always read and save the original dump first. Select chip: 25Q64. Save as backup before any write operation. This is your recovery point. - Firmware Verification
Compare the downloaded dump file size with your backup. Both should match 8MB (25Q64 = 8MB). Verify checksum if available. Do NOT flash mismatched sizes. - Firmware Write (RT809H)
Load the new P50-3663STV5.1 dump file → Select 25Q64 → Auto-detect → Erase → Write → Verify. Ensure stable USB/power connection during the entire process. - Post-Flash Verification
Reconnect the main board. Power ON — TV should display the KONKA logo within 5–15 seconds. Check for correct panel resolution (HV320WHB-N86: 1366×768). Test all inputs. - Final Testing Checklist
✓ HDMI 1/2/3 signal detection ✓ USB media playback ✓ WiFi connection ✓ Audio output (speaker + headphone) ✓ Remote control response ✓ Panel uniformity ✓ Standby / wake cycle ×3
