My vizio p65 c1 won’t display video
My 65 inch tv doesn’t show any picture. The power indicator comes on and off every 9 to 12 seconds. The screen is completely pitch black I did the flashlight test and there was nothing on the screen ( no light grey) except for a faint vizio logo in the middle of the screen and I had to get really close to notice it . I’m still able to SmartCast YouTube for example from my phone, however only the audio comes on . I left the tv plugged in, then one day I come home the screen was on and tv was working fine again. Then after turning it off that night it went back to doing the same thing the next day. Any idea what could that possibly be ?
ANSWERS:
"'''++cbernlool++''' disconnect everything from the back of your TV. Then disconnect the power. Hold the power button for about 1 minute. Then plug the TV back in. Connect only one input. Use something like coax input and see if it displays. If not check all the other inputs as well. If that does not show anything you’ll have to open the back of your TV. Take a look at all the boards for obviously damaged components. Check the connectors as well. Post some pictures of your boards with your question so that we can see what you see .Use this guide Adding images to an existing question for that.
“except for a faint vizio logo “ sounds like either a backlight or a main board issue. I would focus my attention on the power to the LED’s . Start with measuring that voltage to see what it is and if your backlight LED’s get power."
