LG TV fades to black immediately after turning on
Hello, as of yesterday my LG 43uk6470plc TV has an issue. I read some similar posts but none that match the exact issue I have.
- After turning it on, there is a fade out to black from left to right in about one second, just long enough to show the channel number in the upper right corner
- The backlight is still on, no image can be seen with a flashlight
- Audio still works
- The red LED on the bottom blinks a few times on start-up
I've left the power off over night which didn't make a difference. Today I popped off the back and I'm not seeing much out of the ordinary (no blown capacitors) but there is some yellow substance which I assume is glue or something but I'm not sure
Does this description ring any bells for anyone? I'm not very experienced with hardware issues myself, any suggestions are appreciated!
Cette question est-elle utile ?

have you checked to see if its a firmware issue sometimes updates can fail. also have you checked to see if the hdmi cables are worn out or not connected fully bothe these can cause a black screen

Not even the WebOS menu of the TV appears, it's completely black - even without the HDMI cable plugged in. So I'm quite certain it's a hardware failure

Blinking LED generally point to the problem depending on the number of blinks. Count them and look it up based on your make and model. Usually it is the same for any model of a particular make.

@rvdl Can you let me know if the t-con board switch helped you? Because I'm having the exact same problem and I don't know if I should buy a t-con board or get it repaired.

Didn't work out at all in the end, I ordered the part and got help from a friend more proficient in this stuff but he couldn't replace it without some specialized tools. Just got a new TV instead. They don't make these to be repaired :(
