FAQ
TL;DR: Fix Saba TVs stuck at startup by USB recovery; the standby LED doubles blink speed after about 1 minute—"update completed." [Elektroda, billobirillo, post #21089569]
Why it matters: This restores boot on Saba/Changhong-made sets without costly board swaps and answers common "how do I fix boot loop" searches. This FAQ is for DIY techs and repairers solving Saba logo-loop issues.
Quick Facts
- File to use: SISEU23X8M_66.bin on a blank FAT32 USB stick. [Elektroda, billobirillo, post #21089569]
- Visual cue: standby LED blinks slowly, then doubles speed after ~60 seconds; then power-cycle. [Elektroda, billobirillo, post #21089569]
- If USB fails: replace/program SPI FLASH U5 25Q64 with the same file. [Elektroda, billobirillo, post #21089569]
- S3214R variants: need board TP.SIS231.P83 and panel M320X13-E3-L(G3) for the provided software. [Elektroda, billobirillo, post #21731092]
- After recovery, TV starts in first-installation mode (initial setup). [Elektroda, billobirillo, post #21089569]
How do I fix a Saba LDE40TD1051E(T) stuck on the boot screen?
Use USB recovery. Copy SISEU23X8M_66.bin to an empty FAT32 USB. Unplug power, insert USB, reconnect power. Watch the standby LED; when it doubles blink speed after about 1 minute, the update is done. Unplug power, remove USB, then power up. The TV will enter first-install mode. [Elektroda, billobirillo, post #21089569]
What file do I need and where do I put it?
Place SISEU23X8M_66.bin in the USB root directory. Use a single partition, FAT32 format, and keep the drive empty except for this file. This naming and placement are required for the bootloader to detect the package automatically during power-on. [Elektroda, billobirillo, post #21089569]
How long does the USB recovery take and what should I see?
Expect about 1 minute. The standby LED flashes slowly at first, then switches to a faster blink rate to indicate completion. Power off, remove the USB, and power on to finish. "Update completed" marks success in the shared steps. [Elektroda, billobirillo, post #21089569]
It won’t start from the USB stick—what should I try next?
Handle the common failure path: replace the SPI FLASH U5 25Q64 and program it with SISEU23X8M_66.bin. Faulty flash can block USB recovery. After programming and refitting the chip, the set typically boots normally. [Elektroda, billobirillo, post #21089569]
What if the main board is a Changhong variant and USB still fails?
Read the original SPI FLASH, write its content into a new memory, and install the new chip. This approach restores boards that reject USB boot due to flash corruption or wear. It’s a known fix on Changhong-based cards. [Elektroda, Lolo81700, post #21363844]
What is the SPI FLASH U5 25Q64 in this TV?
It’s the 8‑pin serial flash (64 Mbit) storing the TV’s firmware. When corrupted, the TV can loop on the logo. Replacing and programming this chip restores the firmware so the TV can pass initialization. [Elektroda, billobirillo, post #21089569]
Will I lose channels and settings after recovery?
Yes. After a successful update, the TV boots into first installation mode. You’ll need to redo language, region, inputs, and channel scans as part of the setup wizard. [Elektroda, billobirillo, post #21089569]
How do I recover a SABA S4015R with the same symptom?
Obtain the correct software first. If unsure, share a photo of the rear sticker or provide the serial number that starts with G9. This ensures the right build for your hardware variant. [Elektroda, billobirillo, post #21463758]
How do I recover a SABA S3214R and what codes matter?
Match both mainboard and panel codes. For S3214R using TP.SIS231.P83 and panel M320X13‑E3‑L(G3), use the provided software for that combo. If codes differ, request the correct package. [Elektroda, billobirillo, post #21731092]
Step-by-step USB recovery (3 steps)?
- Copy SISEU23X8M_66.bin to an empty FAT32 USB.
- Unplug power, insert USB, reconnect power; wait until the LED blinks faster (~1 minute).
- Unplug power, remove USB, reconnect power; complete first-install setup. [Elektroda, billobirillo, post #21089569]
Do I need the serial number or sticker info before flashing?
Yes, when asking for software for models like S4015R, share a photo of the back sticker or the serial starting with G9. This verifies the exact variant and avoids panel/board mismatches. [Elektroda, billobirillo, post #21463758]
Can I leave the USB inserted after the update finishes?
No. Power off, remove the USB stick, then reconnect power. Leaving the drive inserted can retrigger the loader on the next boot. Follow removal before final power-up. [Elektroda, billobirillo, post #21089569]
Has anyone confirmed this fix works on the LDE40TD1051E(T)?
Yes. A user reported the TV exited the startup screen and updated as described, thanking the helper for the solution. That confirmation matches the shared steps. [Elektroda, viniciusmaiaeng, post #21089601]
Any proof of success on other Saba models?
Yes. A SABA S3214R owner confirmed the provided board/panel-specific software revived the TV, calling it a second life. That validates the model-matched package approach. [Elektroda, gerardor, post #21731515]
What’s an expert’s one-line advice for this fault?
"Copy the file SISEU23X8M_66.bin on an empty USB stick FAT32 formatted"—start clean to ensure detection. [Elektroda, billobirillo, post #21089569]
Edge case: USB ports dead—can I still recover the TV?
Yes. Program a new SPI FLASH U5 25Q64 externally with the firmware file and replace the chip. This bypasses non-functional USB hardware. [Elektroda, Lolo81700, post #21363844]
