Hi. I have a problem with my Philips 28pw6305/01. I was playing PS2 when it suddenly was a noise in the speakers and the screen went black, the "power light" was blinking rapidly in bright and faded red. So i turned the set off and unplugged it. When i later tried it it worked fine for about 30min then it just shut itself off. I have had some small problems before with it being "locked" when i can not change channels or turn it of with remote, back the i used the main power button to turn off and on again and it worked fine after that. Does anyone have any idea what caused this problem? The set is about 4-5 years old i think. Please help!!!
