Hey guys. I've tried searching and haven't found it online anywhere. I looked in the EEPROM dump thread above and it's not there. Does anyone know where I can get the files to flash on an EEPROM for this board? No one sells the eeprom already flashed but I can flash it myself if I can get the files. I've picked up 4 of these tv's in the last 6 months that had a bad eeprom that I've had to just strip the parts and I'd like to start fixing them if I could. Thanks

dick_barton - I haven't tried on this set but I did try a previous set because I have done that very thing with sony's. I'll dig up my flash drive and try on this one.
diif - Is the EEPROM pre-programmed? I have tried searching for a pre-programmed eeprom and have not found anything. Do you have a link for a pre-programmed eeprom?Comment

I don't have a link at present, i'm not near my pc. It wasn't hard to find though. The Nand was described as being the fix for a freeze with the LG logo and was about $30 and the eeprom was under $3Last edited by diif; 03-12-2017, 01:50 AM.Comment

Yes, I found them for other models at 30 but nothing for this model. There was also a guy selling them for a similar model on ebay but he is out of stock. Correct me if i am mistaken, I have to use one orogrammed for this tv, I can't just use any because of the different panels being used,Comment

Hi all,
I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
🔥 The Problem Started After Suspected ESD/PD Fault
I experienced a power issue or ESD event through a USB-C charger
After that, the NX20P5090 power switch was visibly burned and was replaced
Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
🧠 What I’ve Done So Far

Hello, I'm stuck in troubleshooting…
The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.
In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
When I press the flash button, it's detected by the system, flash icon appear on LDC display.... -
Hello,
I am trying to repair a Dahua NVR4216-4KS2 that is not booting.
The main BIOS/firmware is stored in an SPI flash EEPROM (Winbond 25Q128, labeled as U130 on the PCB).
I have a CH341A programmer and I already attempted the following steps:- Identified the correct chip (W25Q128, 3.3V SPI flash).
- Tried to read the contents with CH341A Programmer software. The dump seems corrupted and I often get the error: “Chip with the contents are in disagreement.”
- Compared several chip type selections (24Cxx and 25Qxx families) to confirm it is indeed a 25 series SPI

Hello I've had somebody bring in one of these charming little cameras to attempt retrieving data from the internal 32GB flash.
Something is damaged inside the cameras lens assembly I can hear it clunking around and it has probably dislodged the sensor, powering up the camera gives a blank screen and the focus motor sounds like it's having a fit.
The camera will not connect to a computer via USB in this state, I have no options no navigation, just power up and focus/zoom motor noises.
I think my best shot is to figure out a way to read the internal flash memory outside... -
HI guys
I got here a Sony 65X950G - I tried to find any repairs guides for this model but not many online
here is the issue
I have Sony and android logo. but then 4 led red flash lights front of the tv
I have 3.3v ref. 12v reg then T con 12v when I press the power on button
but then I get black screen and 4 red flash light at the front LED
but I get 3 led flash on the LED driver board.
I check that few X900F or C YouTube repairs, seems that if you have 4 led red flash it could be due of LED black light error
so I tried...
