Westinghouse sk-32h570d sound no picture

After ignition of the back light, a control voltage will come from the main board, to control the intensity of the back light. This is true to all LCD TVs. You should check, whether this control voltage [a variable voltage according to picture displayed on the screen]. If it is not present, make sure that the main board is faulty, as this voltage is generated at the main board and send to the back light inverter board' to control the brightness. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy Pull up older posts. Surf the site with patience.

Westinghouse 26" HDTV LCD Monitor Power comes on, blue light on the button but no display at all the screen remains black can't even go to menu options

You may have power supply failure, the backlight inverter board may not be getting the 24vdc from the power supply, or the problem can be the inverter board itself like blown fuse. You need to open it up and post back what you see, pictures will help a lot. See my pictures here:
