I have a philips tv 19PFL5422D/27 and when I turn it on the screen shows a speaker symbol in the top left corner, tries to show the picture and goes to a black screen.the blue indicator light comes on and can only be turned off by unplugging it. After I do that several times the picture and sound comes on and after I unplug it and turn it on several times, it will stay on longer and longer when it squeals makes a lot of lines and goes black and will come back on by itself and eventually stays on after doing that 8 or 10 times. Can anyone help me fix it? Is it the resistor I believe it was 3340? My tv was made in 2007.
