Hi,
I have 3 of these TVs for repair with same problem of going to standby after around 10minutes and start again continuously. I have tried a new SPI 25Q40 but fault remains. Am suspecting a CPU problem as it gets a bit hotter than I expect.
This seems to be a common problem in these models. I am 100% sure it is a mainboard issue as I have fitted a spare from a normal TV from a UE40K5607 and stays on (diplay inverted but I managed to rotate in SM using a different display).
Any help appreciated!... -
Hi all,
I got a controller where the left stick was moving left all the time (-1.00 at calibration tool). Even after changing to hall effect sticks it stayed the same and reset and all others things didn't help.
I removed the stick again and even without it calibration tool shows a movement to the left. Anybody knows where the fault can come from? Maybe any bridges or damaged SMD components? -
Dear all,
My issue is the following:
Tv suddenly started to make Strange things and went out. After disconnecting power and restarting, it tried to start but failed. After each attempt it got worse and worse. Now only the Stdb light is on and it is not booting.
I checked the power supply -> Backlight on when disconnected from mainboard, so I guess Power supply is ok.
Additionally the upper right part of the main-board makes some whistling noise -> probably issue there and therefore issues with booting
Question 1: Where should I start to... -
Got this tv and tracked down the problem to the mainboard. Tv standby light shows the tv turns On but no picture or backlights. Tested backlights with backlight tester and all is working well. Also I put in another mainboard to verify and backlights turn on fine.
Anyways I cannot find another mainboard for this TV. So I'm trying to fix the board. Any suggestions on where to start?
Could it be the eeprom possibly?
I don't work on many lg TVs and usually when I do it's the backlights.
Thanks I'm advance

Hi everyone,
I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.
🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.
I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.
⚠️ New Problem: One USB-C Port Only Works in One Orientation...
