⚠ Known Issues & Symptoms
This firmware dump resolves the following commonly reported issues on the Echosonic ESTV22A/D-HD6 with the TP.MS3663S.PA671 board:
- Stuck on Logo / Boot Loop — TV powers on but freezes on the Echosonic splash screen, then restarts continuously.
- No Boot / Black Screen with Backlight — Backlight turns on but no picture or OSD appears, indicating corrupted firmware in the SPI flash.
- Dead Set After Power Surge — Board does not respond after lightning or voltage fluctuation; standby LED may blink abnormally.
- OSD Menu Corruption / Garbled Display — On-screen display shows random characters, distorted menus, or missing language options.
- No Signal on All Inputs — HDMI, AV, and USB inputs report “No Signal” despite functional source devices connected.
- Audio Present but No Video — Sound plays normally but the screen remains black or shows vertical/horizontal lines.
- Automatic Shutdown / Random Restart — TV turns off after a few seconds or minutes of operation without user intervention.
- Channel Scan Failure — Tuner cannot find or store channels; digital tuner appears non-functional.
- Firmware Update Failure Recovery — TV bricked after an interrupted or failed USB firmware update attempt.
- Standby LED Blinking Pattern — Power LED blinks in a repeating sequence without the TV turning on fully.
Important: If the issue is hardware-related (e.g., failed capacitors, blown ICs), a firmware flash alone will not resolve the problem. Always perform a hardware inspection first.
🩺 Diagnostic & Repair Protocol
Follow this step-by-step protocol to diagnose the fault, prepare the hardware, and flash the firmware dump to the 25Q64 SPI memory on the TP.MS3663S.PA671 board.
Phase 1 — Pre-Diagnostic Inspection
- Visual Board Inspection: Disconnect the TV from AC power. Remove the back panel and visually inspect the TP.MS3663S.PA671 board for burnt components, swollen capacitors, cracked solder joints, or signs of liquid damage.
- Power Supply Verification: Using a multimeter, verify that the PSU outputs the correct voltages (typically 5V standby, 12V main) before connecting the mainboard. Replace the PSU if voltages are out of specification.
- SPI Flash IC Check: Locate the 25Q64 SPI flash IC on the board (refer to the image above). Ensure the IC is not physically damaged, and that all solder pins have continuity.
Phase 2 — SPI Flash Extraction & Backup
- Desolder the SPI IC: Using a hot-air rework station at 350°C with flux, carefully desolder the 25Q64 IC from the board. Clean residual solder from both the IC pads and board footprint.
- Mount on Programmer: Place the 25Q64 IC into the SOP8 adapter/clip connected to the RT809H programmer. Ensure correct pin-1 orientation.
- Backup Original Dump: Before writing new data, read the existing contents and save as a backup .bin file. This allows rollback if needed.
Phase 3 — Firmware Flashing
- Erase the IC: Perform a full erase of the 25Q64 chip using the RT809H software. Verify the erase operation completes without errors.
- Write the Firmware Dump: Load the downloaded TP.MS3663S.PA671 firmware .bin file (Echosonic ESTV22A/D-HD6) into the RT809H software. Click Write and wait for the process to finish.
- Verify the Write: After writing, use the Verify function to compare the IC contents against the source file. The verification must return 0 errors.
Phase 4 — Reassembly & Final Test
- Resolder the IC: Carefully solder the programmed 25Q64 back to the TP.MS3663S.PA671 board. Inspect all 8 pins for proper connection and no bridges.
- Reconnect & Power On: Reconnect all ribbon cables, LVDS cable, and speaker connectors. Connect the PSU and power on the TV.
- Functional Verification: Confirm the TV boots to the home screen, navigates menus, receives channels, and all inputs (HDMI, AV, USB) function correctly. Test audio output and remote control responsiveness.
Technician Note: If the TV does not boot after flashing, re-check the SPI IC orientation, solder joints, and ensure the correct panel resolution (FHD) is matched. An incorrect panel configuration will result in a white screen or no display.
