Hello. I also have a samsung ue65mu6172 with the bn41-02568b motherboard that doesn't turn on and doesn't have the standby LED. From what I saw in the hex of the W25Q40CL chip, it seems to be corrupted at first. Can you help me with its repair? Thank you very much!Leave a comment:

Hi, I have a Samsung TV model UN43MU6100GCZB (mainboard BN41-02568B BN41-02568). It first had random HDMI issues, then progressed to turning on with backlight but shutting off after a few seconds. All main power rails are present. Could you please check this dump? I suspect its the main problem. Thanks a lot!Leave a comment:

My dear lotas,
I ordered the Winbond W25Q40BVSNIG and W25Q40CLNIG chips to check if there will be any difference.Leave a comment:

Don't make me laugh, where did spi flash get the I²C Protocol from, it's not eeprom.

then start to laugh lotas, script written as befehl which SoC do it as I2C act via eMMC / NAND firmware , when position of script address at SPI or eEPROM different the SoC will take order but it cant deliver it to Main Firmware.. this called Step BY Step start..Leave a comment:

W25Q40BVSNIG have difrent clock signal at I2C will not take effect as the CLLeave a comment:

I desolder the SPI chip and clamp it with a clip. I haven't had issues with this before.
Will the Winbond W25Q40BVSNIG chip work?

Hi all,
My UN65MU6300FXZC is dead and the standby LED stays off. The power supply is good. The main board is BN94-12434A.
Disconnecting the main board from the power supply makes the backlight come ON.
I did disconnect the panel cables and the WIFI modules, the board is still dead.
I did read in many posts that IC1604 25Q40 becomes corrupted. It has proper 3.3 volt on VCC pin 8. I did read that if I post its dump here someone can fix it. Is that right?
Thanks. -
Hello, I need a dump of the BIOS_WHP1 /25Q40/, EC controller chip /NTC6686D/. The motherboard is coming for repair after a another service, what is in the dump that I downloaded is the beginning of the MAIN BIOS, according to the analysis that I did based on the documentation of the EC controller NTC6686D, the content should be different. BIOS_WHP1 /25Q40/ is connected directly to SCE1#, SO1, SI1, SCK1 pins 66, 68, 67, 69 of the NTC6686D01-28-2025, 04:48 AM -
Hi everyone,
I’m looking for the **full 512KB (25Q40) SPI dump** for **TP-LINK TL-SG1016D V7 (unmanaged)**, PCB code **KB616010558**, with SoC **RTL8382L + 2×RTL8218B**.
My current dump only initializes 8 ports and the LEDs are misaligned, so I believe I have a firmware from an 8-port model.
I need a complete dump (bootloader + firmware) from a working switch to restore full 16-port operation.
If anyone has this model or a similar V7 revision, please share the BIN file or point me to a resource.
I can provide photos of my board and the flash... -
Hello, everyone!
A co-worker gave me a 55-inch Samsung TV model UN55MU6103F so I can try to fix the following problem... As soon as I plug it in to the wall, the TV turns on, and the display shows a few stripes all over the screen. I took off the back cover and disconnected both ribbon cables that go to the display (one at a time) so by doing that I can narrow down the bad section of the problem, but in both cases the display turns black. I know there are some voltages that I have to check (VGH, VGL, etc.) but don't know what reading each has to show. If anyone could guide me on this,... -
Could you help me...
I have a Samsung UE55MU6102K with the following problem : I disconnect the motherboard from main power supply from and the backlight leds light up.
Then motherboard connected, standby led is on and current consuption is 18W.
Then trying to start the TV, the standby led is blinking once but TV don't start and standby led stay red.
Maybe the firmware in the IC SPI Flash W25Q40CL (IC1604) is corrupted.
The model of my TV is :
Power supply BN44-00807A
Main Board BN41-02568B / BN94-12765W
Panel CY-GM055HGLV3H...
