I have a tevion lcd4203 42inch that wont turn on the standby button just flashes

So what is your TV: LG 42LC2D or LCD4203?

I'd check the exact model on the back if I were you.

In LCD TVs this could be caused by either bad power board or bad main board.

In plasma TVs this can be caused by other boards as well.

If it's an LCD the first step is to verify the power board.

if it's a plasma it's usually to start eliminating other boards by disconnecting them from power to see whether and when will the auto-shutting (the blinking LED) disappear.

Probably the easiest thing to do is to send the power board to someone who knows how to test it independantly.

If you want to do that feel free to contact us or just find a local provider.

Yellow line down side of screen 42inch lg plasma

If the line is only a pixel in width, then I suspect the LCD panel is at fault. If out of warranty then in most cases the cost to repair it will exceed the cost of replacing the TV. Please take a moment to rate my response. Thank you.
