Question about Westinghouse Televison & Video
I would also say its the inverter board if you have a very dark picture that is barley visible.
inverter board - Dark picture barely visible
power supply - if lcd will not turn on at all
lcd controller - if lcd will turn on but picture fails after a few minutes after being heated up or have scrolling lines threw picture. (try heat sync and thermal paste on lcd processor chip)
Main board - System will not book (less likly but if your components are bent or tweaked it could be a possibility)

You need to replace the inverter board. The lamp failing is very uncommon, moreover LCD Tvs have more than one lamp, and they do not fail all at once.
The connection cable from inverter to main board must be tested, the inverter must be tested, then the inverter must be replaced.
If you DIY remember that the inverter is an high voltage board.
