The power comes on and the sound stays on but screen remains black. No menu or changed sources which I can hear source changing because of Audio but screen remains black. TV only 18 Mo old and never have played video games on it.
Check to see if there is a back light glow to the screen of the tv when you plug it in with a power cord. Use a flashlight test and shine it against the screen to see if there is an image. If there is no image then your T-con board could be defective. The T-con board is the part of the tv that gives you image/video. Have a certified tech come out and check it and replace the tv if you still have warranty.
Bad inverter board change it
SOURCE: no picture
It sounds like the backlight is out. If you can see a faint image that changes then this is the case. You either need to send in for repair or replace. It can if you are lucky be a connection. You can try removing the video cable and try another source or cable.
