FAQ
TL;DR: The 17MB130S mainboard in this F&U set uses a 16 Mbit (2 MB) SPI flash; "16 Mbit (2MB) flash memory". Firmware mismatches or oversized images cause boot loops or black screens. [Elektroda, cabrinha, post #21516864]
Why it matters: This FAQ helps owners recover a non‑booting FL2D4903UH and request the correct firmware.
Quick Facts
- Model/stack: F&U FL2D4903UH with 17MB130S mainboard, 17IPS72 PSU, panel VES490QNDS‑2D‑N12. [Elektroda, cabrinha, post #21516864]
- Symptom profile: standby LED blinks; set won’t start; remote makes LED blink faster. [Elektroda, cabrinha, post #21516864]
- Post‑update failures: several owners report black screen and nonstop LED blinking after an online update in Dec 2025. [Elektroda, panosptr, post #21770998]
- Edge case: no LED at all despite correct board voltages was reported. [Elektroda, abramkyr1995, post #21722736]
- Firmware help offered for similar combos (Digihome/Telefunken); contact was requested by the sharer. [Elektroda, fadili, post #21522134]
Which exact firmware do I need for FL2D4903UH with 17MB130S/17IPS72 and VES490QNDS-2D-N12?
Match firmware to all three: mainboard 17MB130S, PSU 17IPS72, and panel code VES490QNDS‑2D‑N12. A user tried a VES490QNDL‑2D‑N11 image and found it unsuitable due to size. Panel code mismatches often brick the TV. Request a dump matching your N12 panel. [Elektroda, cabrinha, post #21516864]
Why does my TV blink red and never start, even when the remote makes it blink faster?
This pattern indicates the mainboard attempts to boot but fails integrity checks or panel init. The report shows power and LED bars are OK, so logic firmware is suspect. Use a panel‑matched software package for 17MB130S to restore boot. [Elektroda, cabrinha, post #21516864]
I allowed an online update and now I get a black screen with nonstop LED blinking. What changed?
Owners who accepted the update report immediate black screen and continuous LED blinking afterwards. That points to a corrupted or mismatched software package. Reflashing a correct 17MB130S image for your panel usually resolves it. "Made the stupid decision to let it update." [Elektroda, panosptr, post #21770998]
Can I use firmware for VES490QNDL-2D-N11 on my VES490QNDS-2D-N12?
Avoid that. A user found a VES490QNDL‑2D‑N11 package where mb130_RomBoot_AMZ.bin exceeded the board’s flash capacity, signaling an incompatible build. Stick to images labeled for VES490QNDS‑2D‑N12 to prevent bricking. [Elektroda, cabrinha, post #21516864]
What size is the 17MB130S SPI flash, and why does file size matter?
This board uses a KHIC 25L1606E SPI flash rated 16 Mbit (2 MB). Images larger than 2 MB cannot fit a straight ROM dump, and forced writes risk boot failure. Always verify the image size against 2 MB before programming. [Elektroda, cabrinha, post #21516864]
My TV shows no LED at all, but voltages on the PCB are correct. What’s the next check?
That edge case suggests the standby MCU or bootloader did not start. With rails present, firmware or SPI corruption becomes likely. Try a known‑good dump for 17MB130S or service USB recovery for this model. [Elektroda, abramkyr1995, post #21722736]
Who offered firmware or dumps in this thread and how do I contact them?
User “fadili” stated, “for these combinations i have SW,” and later asked interested owners for an email contact. Reply in‑thread and provide contact details as requested. [Elektroda, fadili, post #21522134]
How do I request the right dump file from the sharer?
- Post your exact labels: model, 17MB130S, PSU 17IPS72, and panel code VES490QNDS‑2D‑N12.
- State your symptom (e.g., black screen after update).
- Share a contact email, as the sharer asked, and request the N12‑matched dump. [Elektroda, fadili, post #21522134]
What is a firmware “dump” on TVs like this?
A dump is a byte‑for‑byte copy of the SPI flash contents from a working board. Technicians write it back using a clip programmer or recovery USB, restoring boot code and settings for the exact panel. [Elektroda, cabrinha, post #21516864]
Is there evidence that power and backlight are fine but firmware blocks startup?
Yes. The origin post confirms PSU 17IPS72 works and LED bars are OK, yet the set only blinks. That isolates the failure to mainboard software or configuration. Firmware matched to VES490QNDS‑2D‑N12 is required. [Elektroda, cabrinha, post #21516864]
I bricked the TV after an update on December 4–6, 2025. Am I alone?
No. Multiple owners posted the same week reporting black screens and nonstop blinking after accepting an update. Join the thread and request the proper image for your panel. [Elektroda, amigogr, post #21771758]
Can Digihome or Telefunken software work on this hardware combo?
A contributor offers software for similar combinations labeled Digihome/Telefunken. Request it and specify your exact panel code to confirm fit for 17MB130S with VES490QNDS‑2D‑N12. [Elektroda, fadili, post #21521324]
What quick statistic helps me sanity‑check downloads before flashing?
Verify the image does not exceed 2 MB when targeting the KHIC 25L1606E SPI device. Oversized images indicate a wrong build or packaging and should not be flashed directly. [Elektroda, cabrinha, post #21516864]
What do local users report in Greek about this firmware issue?
A Greek‑language post asks anyone who solved the software issue to share, noting many people have the same problem. This underscores the need for a correct dump. [Elektroda, jimis411, post #21774100]
What if my panel code label is missing or unreadable?
Do not guess. The thread shows failures when using a similar but different panel code package. Wait for a confirmed dump or read the original SPI from a working twin unit. "Is there another firmware available?" [Elektroda, cabrinha, post #21516864]
