Facing TV Problems? Ask a TV Technician.
Hello and sorry you're having problems. Can you please elaborate on what's happening here?
In other words, you said you "checked backlight with flashlight"- so, is there a shadowy image behind the screen with a flashlight? Do the backlights come on? Does the set have sound?
What exactly happens when you press the power button- does the power light change?
Or is there no power light at all?
