FAQ
TL;DR: Expect to program 2 SPI dumps; "U10 and U12 bin files" are shared to repair this boot fault on Vestel-based 22-inch sets. [Elektroda, billobirillo, post #19518592]
Why it matters: This gives bench techs a fast, low-cost path to revive no-boot Kunft/Electronia 22-inch TVs without swapping the mainboard.
Quick Facts
- Startup symptom reported: standby LED flashes five times on the affected TV. [Elektroda, assistenciaelectro, post #17646900]
- Typical repair uses two SPI dumps (example: "U10 and U12 bin files"). [Elektroda, billobirillo, post #19518592]
- Confirmed success on 17MB55 with AUO T215HVN01.0: "It worked perfectly." [Elektroda, RicardoPT, post #19518940]
- SPI type discussed during diagnosis: 25C32 or 25C64—verify on-chip marking. [Elektroda, hassanelektro, post #19050119]
- USB firmware recovery was suggested as an alternative to chip programming. [Elektroda, querij, post #19523150]
How do I fix the boot/blink fault on Kunft 22LVM14 (Vestel 17MBxx)?
Reflash the SPI firmware. Use the shared "U10 and U12 bin files". These two dumps target the mainboard’s boot data. Back up both original chips first. Program and verify each with a reliable SPI tool. Refit, power up, and test controls and picture. [Elektroda, billobirillo, post #19518592]
Where can I get the U10/U12 firmware dumps for 17MB82S?
See the post titled "U10 and U12 bin files" by billobirillo. Download the attached binaries and program both chips. Match file-to-chip by board silkscreen. Keep your original dumps for safety. Report results back in the thread to help others. [Elektroda, billobirillo, post #19518592]
Is there a confirmed working firmware for 17MB55 with AUO T215HVN01.0?
Yes. A technician reported success on a 17MB55 with the AUO T215HVN01.0 panel. The feedback was, "It worked perfectly." This shows the shared files match that board–panel pair. Flash both relevant SPI devices for that board version. [Elektroda, RicardoPT, post #19518940]
Which chips do I flash on a 17MB55 board?
Use the two dumps provided for that board version. The contributor shared "U114 and U115 bin files" and asked for feedback: "let me know if them works correctly." Flash both and confirm operation after programming. [Elektroda, billobirillo, post #19518915]
Is the SPI flash 25C32 or 25C64 on these sets?
The thread highlights both 25C32 and 25C64 during diagnosis. Read the marking on your chip and match it. Program the correct capacity file to the correct device. When in doubt, post a clear photo for identification. [Elektroda, hassanelektro, post #19050119]
Can I recover the TV software via USB instead of using a programmer?
USB recovery was suggested as an alternative to chip programming. Prepare a USB stick with the correct model firmware. Then trigger the service recovery procedure for your set. Use this only if the board supports USB flashing. [Elektroda, querij, post #19523150]
What panel does the confirmed 17MB55 firmware support?
The reported success used an AUO T215HVN01.0 panel. Ensure your screen matches this panel code before flashing. This pairing was the tested configuration in that report. [Elektroda, RicardoPT, post #19518940]
My TV sticker is missing. How do I identify the right firmware?
Use the mainboard assembly number and the panel brand. One case noted board 23223532 and an AUO panel. Those identifiers help select matching dumps. Photograph the board and panel labels for reference before requesting files. [Elektroda, RicardoPT, post #19519020]
How do I flash the SPI ROMs safely? (3-step)
- Read and save backups from both SPI chips.
- Program the posted dumps to U10 and U12, then verify.
- Reassemble, power up, and test picture, audio, and keys. Two chips must be written for a complete fix. [Elektroda, billobirillo, post #19518592]
What if flashing succeeds but the TV still fails?
Check for a panel or board variant mismatch. One technician noted a similar model had a different panel and board. Reconfirm your exact panel code and board version. Then source dumps that match your exact hardware. [Elektroda, RicardoPT, post #19519132]
What model might an Electronia 22-inch with this board be?
A contributor suggested the identification as "most probably Electronia LD22FHD." Treat this as a lead, not a guarantee. Verify by hardware labels and board numbers before acting. Panel and board must match the shared firmware. [Elektroda, billobirillo, post #19519049]
Did anyone obtain the software requested earlier?
Yes. Firmware was later posted as "U10 and U12 bin files." Download and program both devices accordingly. [Elektroda, billobirillo, post #19518592]
