I had a similar problem with my 42 Inch Philips 42PLF5432D/37 LCD HD TV. It would turn on but then shut back off after about 10 seconds. Then it wouldn't turn on at all. The problem was a bad capacitor. Several bad capacitors. They are inexpensive and fairly easy to replace if you don't mind digging around in the back of your set and soldering some new ones on your Power Supply Board. Or take the less inexpensive route and look for a whole new Power Supply Board. Good luck. Hope this helps.

for Bravia's.. To turn off the demo mode, press and hold the MENU button on the TV for more than 10 seconds. The message Demo mode: Off will appear on the screen. Let me know if this helps.

Sometimes the TV will lock out other inputs when a cable is connected. Try the antenna by itself and put the TV in Channel scan mode. If this works reconnect the cable TV cable. If that doesn't work you may need an A/B switch

Serious! If the TV is new, you may check your homeowners insurance for a replacement. The Power company can Verify the power fluctuation for you. When an appliance receives a Power Surge like that, the sensitive electronics are damaged or weakened. For PROTECTION: Get a 1000Watt UPS and use it between the house power and the TV. http://www.tigerdirect.com/applications/SearchTools/search.asp?lowprice=50&highprice=99.99&keywords=1000W%20UPS&cat=&mnf= Try This.
