Screen is black, But sound still present.What to do?
Watching tv and the screen just went black have tried turning off and on and unplugging audio still works fine I can change channels and hear different audio but no pictures through cable component or hdmi.
ANSWERS:
I have a 65" LG, OLED, 4K Ultra HD, Smart TV. I have had this TV for 1 month. The screen just went blank / black but everything else was working on it.... sound, apps pages, etc. but I could not get a video or satellite image at all. I decided to try resetting the TV to it's original setting and it worked. I have a picture again. It is a complete pain as I now have to go back and set everything up again. But at least I can watch the TV again. Hope this helps some or all of you!!!
More than likely you have 1 or more LED's that are shorted out. When this happens the LED strip will draw too many amps and the board will shut down all LED lights as an over-amp precaution. This happened to my 50" LG and I was able to fix it at no cost by removing that particular LED strip from the circuit. It is not a difficult repair, but does require someone to pretty much completely disassemble the TV. If you want to attempt the repair, here is a Youtube video that provides some instructions,
Had a 42 “ LG and after about 18 months screen would go black but sound was still on , rang LG but wouldn’t do anything as it was out of warranty. After 5 years of messing around with it (turning it off and on ) decided to buy a 50” Panasonic which is brilliant ,in the meantime I thought I would take the back off the LG and give it a good clean and push all the connections on securely and tighten all screws ( some of which were quite loose ) we now have the LG on the kitchen wall and it has not gone off at all and that’s after 1 week , it worked for me maybe it could work for you ,good luck
Press volume down key and power button together simultaneously switch OFF main plug and then put it ON again
Well not sure of this will work for every one but my lg t.v just went black when my son turned it on to play x box. I looked online every one was saying buy some chip. I just unplugged the power cord from my t.v and plugged it back in and it turned right on.
