FAQ
TL;DR: MX25L1606E is 16 Mbit (2 MB) NOR flash [“MX25L1606E Datasheet”]; “Excellent eprom dump, works 100%” [Elektroda, mick1066, post #18851885] For Toshiba 32W3063DG/32W3963DG on 17MB211S with VES315WNDB-2D-N21, use a SPI dump when USB recovery isn’t available [Elektroda, Aquario_blue, #18700037; Namik79, #18656184].
Why it matters: This FAQ helps Vestel-based Toshiba TV owners and repairers fix boot/firmware faults fast with the right dump and method.
- Panel/mainboard: VES315WNDB-2D-N21 with 17MB211S confirmed by the requester [Elektroda, Namik79, post #18656184]
- Firmware medium: MX25L1606E SPI NOR flash on 17MB211S noted in-thread [Elektroda, mykola10848, post #20767919]
- Capacity/file size: 16 Mbit = 2,097,152 bytes (2 MB) typical dump size [“MX25L1606E Datasheet”].
- Voltage/interface: 3.0–3.6 V, SPI (3- or 4-wire) per datasheet [“MX25L1606E Datasheet”].
- USB recovery limits: Regional availability can block official packages [Elektroda, Aquario_blue, post #18700037]
Quick Facts
- Target set(s): Toshiba 32W3063DG/32W3963DG; panel VES315WNDB-2D-N21; mainboard 17MB211S [Elektroda, Namik79, post #18656184]
- Working method reported: direct SPI dump (not USB) succeeded for a user [Elektroda, mick1066, post #18851885]
- SPI flash device: MX25L1606E, 16 Mbit (2 MB) NOR, 3.0–3.6 V, 8‑pin package [“MX25L1606E Datasheet”].
- USB recovery caveat: Official recovery may be unavailable if model wasn’t sold in your country [Elektroda, Aquario_blue, post #18700037]
- Edge case: An early provided file failed; matching panel/board matters [Elektroda, Namik79, post #18708203]
Which firmware/dump fits Toshiba 32W3063DG/32W3963DG with 17MB211S and VES315WNDB-2D-N21?
Use a dump matching 17MB211S and panel code VES315WNDB-2D-N21. The request specified this combo, and a later shared EPROM dump solved the issue for another user [Elektroda, Namik79, #18656184; mick1066, #18851885].
Is the fix a USB recovery or a direct SPI dump?
Direct SPI dump. A user asked this and later confirmed the EPROM dump worked 100%. USB recovery was difficult to obtain for this regional model [Elektroda, mick1066, #18850790; mick1066, #18851885; Aquario_blue, #18700037].
What chip stores the firmware on 17MB211S?
The firmware resides on an SPI NOR flash, MX25L1606E (16 Mbit, 2 MB) per in-thread note and datasheet specs [Elektroda, mykola10848, #20767919; “MX25L1606E Datasheet”].
How do I program the MX25L1606E dump safely?
- Read and save a backup from the MX25L1606E (SOIC8) using a 3.3 V SPI programmer. 2. Erase and write the 2 MB dump, then verify. 3. Power-cycle the TV and perform a factory reset if the set boots [“MX25L1606E Datasheet”; Elektoda, mick1066, #18851885].
What file size should I expect for the dump?
Expect 2,097,152 bytes (2 MB), matching the MX25L1606E’s 16 Mbit capacity. Files larger or smaller indicate mismatch or corruption [“MX25L1606E Datasheet”].
Why didn’t one provided file work for the OP?
One early file failed for the requester (“Not work”). Mismatched panel configuration or board variant can prevent boot or cause display faults [Elektroda, Namik79, post #18708203]
Do I need the TV’s serial number to get software?
A contributor requested the serial to try obtaining official recovery. This implies model/region gating on vendor firmware distribution [Elektroda, Aquario_blue, #18674648; Namik79, #18675008].
Why is USB recovery sometimes unavailable?
Official recovery may not be provided when the equipment wasn’t sold in that country, blocking access to USB packages [Elektroda, Aquario_blue, post #18700037]
What voltage/interface do I need for in-circuit flashing?
Use a 3.0–3.6 V SPI interface (commonly 3.3 V). Over-voltage or 5 V adapters risk chip damage [“MX25L1606E Datasheet”].
Can I flash in-circuit with a SOIC-8 clip on 17MB211S?
Yes, if the board allows stable 3.3 V and the CPU isn’t powering the bus. Remove power, isolate VCC if needed, and verify read ID before writing [“MX25L1606E Datasheet”].
How do I verify a successful repair?
After programming, the TV should boot and operate normally. One user reported “works 100%” after using the EPROM dump. Run built-in reset if available [Elektroda, mick1066, post #18851885]
What if my panel code differs from VES315WNDB-2D-N21?
Use a dump aligned to your exact panel code. Wrong panel parameters can cause no image, wrong colors, or boot loops. The OP’s mismatch experience highlights the risk [Elektroda, Namik79, #18656184; Namik79, #18708203].
Which tools are commonly used for this repair?
Use a 3.3 V SPI programmer (e.g., CH341A or TL866), SOIC‑8 clip or hot‑air for chip removal, and verification software that checks write/verify on a 2 MB image [“MX25L1606E Datasheet”].
How can I help others after a successful flash?
Back up and share your verified dump and note the exact model, 17MB211S, and panel code. A contributor explicitly asked for sharing to aid future users [Elektroda, Aquario_blue, post #18700037]
