Westinghouse ld-4255vx no picture	Can't Post

As i stated above. the tv has power going to it but there is no picture. and its a LED tv so i highly doubt its a backlight problem. Any ideas on whats wrong?

Use it as a radio?

(As you say it has "No Picture," one assumes it HAS sound.) Crazy

Funny. but im asking what would most likey cause a LCD tv with a LED backlight to have no picture. Would it be somthing on the main board? or the main board itself?

There are two types of "LED" TVs.
One type uses LEDs to "backlight" an LCD screen (cheaper and considering the brand name is Westinghouse, this is what your set uses).
http://reviews.cnet.com/...6482_7-34553113.html
Technology: TFT active matrix
LCD backlight technology: LED Backlight technology
LED backlight type: Edge-lit
The other type uses LEDs directly to produce the picture.

So IF you DO have sound on the various inputs, (as opposed to NO Sound), I'd still highly suspect backlights or control over same (No enable).
