Hi Lotas, can you fix the file, please?
I tried some other files, but I managed only to have the stand-by led on.
Thank youComment

Hi Lotas,
I tried with the fix file but the TV set is dead. The standby LED turns on for 1 sec every 15 sec. The standby voltage from 8v goes to 13v. At first, the TV was totally dead. Now it looks like there is some life in it but there must be a hardware problem in the mainboard.
Anyway, I want to thank you for your effort and time. I wish you the best. Thank you.Comment

Hi Lotas, my TV model is UN50MU6100GCZB, Board Code: BN41-02568B from Argentina. I'm having the same issue as another user before. The standby LED turns on for 1 sec every 15 sec. When Flashing an incorrect bin, the board stays completely dead. So I guess it could be bios related. could you help me? Thanks in advanceComment

Where did you get the idea that the problem is in these firmwares, if there is no standby mode and the LED is not on, then a common problem in this chassis is IC204 (stabilizer from 5v to 3.3v) and micom Weltrend, check the resistance at 1.2 pin IC203 relative ground and is there 3.3v power on these pinsAttached Filesif you find these attachements useful please consider making a small donation to the site

Thanks for your your support. i found that sub eeprom (24c02) is connected to this ic1203 so i thought this may be the problem.
I measured the regulator and i/p 5.3 v & o/p 3.3 v so it is good, also the voltage at pin 1&2 3.3v and no short with ground. i tried to press the reset button but nothing happened
how can i check ic1203 (61P805) is healthy ??
does it need programing? if yes can it be done by CH341?

What initially happened to the TV? In service mode, at the point you clicked on “Micom Update” and after that the TV stopped turning on?
If yes, then the firmware has been erased in micom, you need to program it.
And also, you have some strange dump 24C512, or it is so badly damaged or poorly read, try this one.Last edited by lotas; 08-19-2024, 11:33 AM.Comment

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...
