I have had a Philips 32 inch lvd tv 32pf7321/79 for about four years and it has always worked fine with one exception. when you turn it on you only get the sound (no video). To get the video you have to turn it of and on again. So to effectively watch it you have to turn it of and on twice initially. I cannot find anything in the trouble shooting pages or elsewhere in the manual that can help me rectify this
