FAQ
TL;DR: For Saba LD40CHD105 fixes, 1 device needs exact-spec firmware; "The software is for one device." This FAQ explains USB update steps and what to check if IR fails. [Elektroda, querij, post #20711314]
Why it matters: A mismatched build can boot yet disable the remote, so match specs before flashing.
Quick Facts
- Reported symptom: Saba LD40CHD105 stuck on “initialisation en cours.” [Elektroda, RoyalC, post #20709013]
- USB update method used: FAT32-formatted drive with the update file copied, then inserted and waited. [Elektroda, RoyalC, post #20716379]
- After update, the init loop cleared; the IR remote then stopped responding. [Elektroda, RoyalC, post #20711382]
- Local side buttons worked normally during the remote-control fault. [Elektroda, RoyalC, post #20713249]
- Full flash reprogramming needs suitable hardware tools, not just a USB pen. [Elektroda, querij, post #20717137]
What’s the quickest way to escape “initialisation en cours” on a Saba LD40CHD105?
A USB firmware update resolved the loop in this case. After flashing, the TV left “initialisation en cours” and booted. However, the IR remote stopped responding afterward. Test basic navigation with the TV’s side buttons to confirm boot status. [Elektroda, RoyalC, post #20711382]
Why did my remote stop working after flashing the firmware?
Because this software targets a single device configuration. "The software is for one device, with the same specifications." If your unit differs from the firmware’s target, features like IR control can stop functioning after the update. [Elektroda, querij, post #20711314]
Do the TV’s side buttons help diagnose the problem?
Yes. In this case, the side buttons worked normally while the IR remote did nothing. That shows the TV accepted local input despite the remote issue, guiding next steps toward firmware or IR handling. [Elektroda, RoyalC, post #20713249]
How do I update the Saba firmware via USB?
Use the tested USB method for this set: 1. Format a USB drive to FAT32 and copy the update file. 2. Insert the USB into the TV and power it on. 3. Wait for the flashing process to complete before removing the drive. "Format FAT32... insert the USB disk and wait for the flash." [Elektroda, RoyalC, post #20716379]
My TV’s LED blinks when I press the remote, but nothing happens. What does that tell me?
In this case, pressing a remote button made the TV LED blink, yet no command executed. That observation came after a firmware update, indicating the set saw input but did not perform actions. [Elektroda, RoyalC, post #20712720]
Can someone repair my original BIN and generate a USB update?
Yes. An expert offered, "Publish a defective bin! I will make your faulty usb bin!" Share your dump so they can rebuild a compatible USB package for your unit. [Elektroda, jeloi, post #20714919]
Was the posted USB file custom-made for this TV?
Yes. The contributor confirmed the file in the referenced post was “specially made... for your TV” and prepared for USB flashing. That targeted build addressed the request without needing hardware programmers. [Elektroda, jeloi, post #20723573]
Did that custom file restore remote control?
No. In one case, flashing the custom USB file did not restore IR control; the TV’s LED still blinked, but no actions occurred. This edge case shows a deeper mismatch beyond that package. [Elektroda, RoyalC, post #20726631]
Do I need special tools to reprogram the flash chip directly?
Yes. "You would have to have suitable tools, it is not done with a pen." Direct flash programming requires hardware-level tools and skills beyond a simple USB stick. [Elektroda, querij, post #20717137]
If I don’t have those tools, what’s a practical next step?
Stick with USB updates and collaborate with an experienced helper. Publish your defective BIN so they can craft a corrected USB image tailored to your unit’s configuration. [Elektroda, jeloi, post #20714919]
Is this firmware unique per device or per model variant?
Treat it as device-configuration specific. As one expert put it, "The software is for one device, with the same specifications." Verify exact hardware details before flashing any build. [Elektroda, querij, post #20711314]
What should I share to help identify the right firmware?
Post clear photos of the mainboard, modules, and labels. The OP opened the TV and shared images, helping others identify hardware and advise on compatible software paths. [Elektroda, RoyalC, post #20709013]
