Hello, here is a UE50MU7000 with BN41-02568B (after an electricity jump):
- no stand by led light
- power supply has 9v outputs which go to mainboard
- without mainboard connected backlight works fine
- without backlight connected still no stand by led light
- dumped 24C512, 25Q40, 25Q80 (through CH341A programmer before finding this site), and flashed backup data from a UE40MU6102KXXH (which has same main board), this did not fix anything
After reading this thread, found out there is a specific way of flashing 25Q40, so I've placed all original backups back to their chips (also tried to restore header data in 25Q40, but it did not work)
and while doing what is in guide in 4th post, found out that QE is impossible to check. (edit: in NeoProgrammer V2.2.0.10 it's possible)
Is there also a special way of flashing 24C512 and 25Q80 like 25Q40 requires?
Can you please take a look at these files and see if there is anything wrong?
Can send a thanks thru PayPal if it will fix this issue.Comment

Anything could be wrong, for example, the firmware in the NAND or in the eeprom, is your backlight OK?Comment

yes, the samsung logo shows off for several seconds with backlight on then the logo goes off and backlight stays on for some seconds then the tv reboots. i cant find the eeprom ic. photo of the board attached.
thanks for your help.Comment

It's hard to tell from this photo, but the eeprom should be 24c256.Comment

by YanlebHi 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. -
by ogabugaHello, 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 NTC6686D

by daniel0799Hi 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...-

by alro7779Hello, 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,... -

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... - Loading...
