You have to be very careful with the flat ribbon cables and be sure not to have an electro static discharge to the board while handling it but it is not that difficult of a repair. It is the board that is located at the top center of the back of the lcd panel. Depending on your problem, eg. line in picture, no picture with backlight.... it unfortunately only fixes about half of the units. The other half need lcd panels which are very expensive. hope this helps.

Just reset the TV found out how here: http://www.danielcoburn.com/uncategorized/westinghouse-1080p-42-lcd-tv-hdmi-stopped-working-fix/
Hold the power button for 10 seconds.

I know this is late, but this happens frequently. If anyone else has the same problem try unplugging the TV for 60 seconds. Plug it back in and then hold the power button down for 30 seconds.
That will reset the TV.
You should see the Westinghouse logo come up and the HDMI should work. This has happened twice with my TV in 1 year.
