i have had a Philips LCD TV 42PFL3704D Full HD 1080p digital TV with Pixel Plus HD for about 2 years and have had no problems with it. Today when i turned it on, it stayed on the "Philips" screen for a about 10 minutes, when it finally went away i could select through my inputs with the the remote but no picture or sound from any. I have devices on HDMI 1 & 2, Video 2 & TV. The buttons on the TV were unresponsive. Any recommendations or fixes are appreciated.
