powers on then 10 seconds later picture goes blank
I have a Sanyo clt2054 -04 it powers on then 10 seconds later picture goes blank and everything else works and sound
shanechitwood40 once the picture turns dark (in a darkened room) shine a flashlight at an angle against the screen. See if you can make out shapes etc. If so, it is your backlight that is failing. If it does not, you want to remove the back of your TV and take a look at the main board. Check for any obviously damaged components. Take some good pictures and post those with your question so that we can see what you see. Use this guide 在已经存在的问题里加入图片 for that.
Of course, you can also go ahead and measure the voltages as outlined here
That will allow you to figure out where on the mainboard the issue is.
