Question about Philips 30PF9946 30 in. HD-Ready Plasma Television

3 Answers

Black screen with sound. Problem on every channel.

The TV worked fine when we went to bed. In the morning it turned on with a black screen and had sound. We have checked all the cable connections (We have cable fine on our other TV). We have tried to pushing different buttons on our remote as suggested by the usuers manual (this did create our sound to go off since we could not see what results we were getting from pushing these buttons). We have been told that plasma TVs have a life of only so many viewing hours, and ours may have just died. Our TV is over two years old.

Re: Black screen with sound. Problem on every channel.

Sound no picture or shut down Power led starts green then a short amber then turns RED . If your power supply can be confirmed to be go you have a bad Inverter board. Per the manufacture this part comes only with the panel . Not cost effective . But if you go to you will locate an inverter for $ 169.99 . I had the same problem and the inverter repaired the set . Note there are similar error codes but from what I can see from all of your complaint I do be leave that your Inverter is bad . Good luk

Re: Black screen with sound. Problem on every channel.

Has not died = needs repair by qualified tech......
Did you try hard reset by unplugging ac cord for a while?
Next, voltages need to be checked inside TV.........
Let me know where this repair is going........T.

Had the LCD TV For 5 Years, no problems, then just before going to bed i was about to turn off the tv when the screen went black but sound was fine. I switched channels and you could hear the channels...

Your problem can be related to either LCD backlight inverter failure or T-con board failure. Please turn on your tv, darken the room and see if you notice a dull glow on the screen. If you see a dull glow then backlight is functional and the t-con is dead. Otherwise it can be a backlight inverter failure(in some cases the backlight itself). In that case I would try replacing the backlight inverter board and hope its not the backlight as the backlight is embedded into the the panel and the only way to replace it is to replace the panel.

Black out screen

I had the same problem once with my RCA television. It only happened on certain channels and didn't happen during commercial breaks. If I adjusted the volume on the tv the box went away, but came back shortly after. The problem ended up being some malfunction in the closed captioning. I turned it all off and changed the CC settings and never had the problem again.
