i have a westing house lcd tv i have sound but no picture?

when i turn on the tv the picture comes on than goes right off and the sound stays on is there a part i can buy help me please

This is a common problem with Westinghouse LCD TVs!

To help narrow down the problem, you need to know if the TV 'glows' when the picture is lost. Best way to tell is to turn off the TV in a darkened room. Then turn it on. If it is glowing, you will see it. If not, the screen will remain dark!

If it does glow, the problem is the TCON board. Also known as the LCD controller board. It's what controls the pixels of a LCD TV and is located on the back of the TV on the top. It usually is covered by a heat shield.

If it doesn't glow, the problem is the back light inverter boards. These control the back lights of the TV. And depending on the size of the TV, there should be two boards...one on each side of the TV in back. These usually have heat shields too!

None of these boards are difficult to replace. It just takes some patience and a little technical know-how to remove a few wire connectors and screws! If you run your TV's model number on sites like Ebay, you should be able to find these boards. Note that it's best to have the numbers from the boards themselves when doing searches! Sometimes there are similar boards that are meant for different TVs!

Example: Westinghouse 40" LCD(LTV-40w1)...
