The picture will not come on. Only gets sound. What is the problem? The picture would take about a minute to come on and then it would take a little longer and then nothing at all.

Hi jsevcik897, 
I am happy to help, we need to check the backlight inverter.

  1. Turn tv on and get to a point that you have audio.
  2. Take a flashlight and shine it on the screen.
  3. Look very closely at the screen for a very dark video image.
If you see an image you have a bad inverter, you should be able to replace it yourself. I can walk you through in chat. Let me know your findings. Lone99star

47in Phillips-tv picture goes black still has


Could be the signal board has a bad cap, in this case it sounds like you are getting intermitten power to the inverters....when the tv goes down and of course you have audio....Shine a flashlight on to screen and see if you have a picture...look carefully. If this is the case..you have the above problem!

Buzzing and poor recption


I wish I had a solution--My DVD picture and sound is fine, but it takes about 30-40 minutes to get any kind of picture but it is broken--not clear at all - and the sound is all garbled, totally stops for seconds to minutes a a time. It is only a little over a yr old. I finally isconnectexd today and am going back to my cheap-o but dependable tv.
