Question about Philips Televison & Video

2 Answers

Hi. We have a Philips FlatTV. Occasionally while I have been watching TV lately, the video goes out (while I can continue to hear the audio just fine). I was able to simply power down the TV and audio receive with our universal remote and turn everything back on to "restore" the video just fine. Now, I can't get any video! I can change channels through the universal remote, play DVDs through the universal remote -- while always hearing the audio of what I am playing, but no video. When I manually turn off the TV using the TV's power button on the side of the TV and then turn it back on, we see a very quick "blue screen" briefly as if it's trying to display the video (as it usually did) and then the screen goes quickly to black again. HELP! Can anyone shed light on why "all of a sudden" we no longer see any video. The TV is just five years old.

    Hi.



    Unfortunately, the TV is hanging on the wall and therefore I can't get to the back of it to confirm the model number; however, the manual has two printed model numbers: 30PF9946I37 (or, is the capital "I" really a "1" -- it's hard to tell b/c the manual uses sans serif font), 37I42PF9936I37. Not sure if this helps or not?



    I should note that after I hastily posted my question, I was able to find other questions users asked describing the same problem. Solutions discussed "temperature sensors" and "power supply" issues (which prevents the TV from turning on as self-protection) as well as replacing various "boards" and such -- all way too technical for us to ever figure out or fix on our own. Plus, we can't easily get to the various connectors and such since the TV is attached to the wall.



    So, after many tries at turning the TV on/off repeatedly, we unplugged the cable box for a few minutes and then plugged it back in "for kicks". Lo and behold, when we turned the TV back on, the video was restored. Is there a correlation there? If so, can you explain why?



    While we got the video working once again, I am concerned about a larger issue, and whether we will need to think about replacing the TV in the near future.



    Any advice would be greatly appreciated.



    Thanks, Ana

    Hi ana


    just got your messages and will be right back with you

    Jacques Marin May 04, 2010

    O.k i`m back with you and did some research on your model, which is 30PF9946.


    With your first description of the problem , i was leaning towards the backlight inverter board which lights up the display.


    But now with the last info i`d say that the problem is with your cable box.


    One way to find out would be to try a dvd player or any other source of signal if the problem occurs again.

    Also ; i know sometimes it may be confusing to use this site, and usually i get the new comments added right away.


    But sometimes i may get them much later on or not at all, this is a bug in the email system that fixya is working on.


    So i will check this post regularly to see if you have new comments.

I have a Philips soundbar that I have hooked up to my flat screen tv using audio (red,white) cables directly from soundbar to tv and there is no sound coming out.


Be sure you are hooking up the Audio Output from the TV or satellite to the soundbar.

From the satellite box both Audio Output and Video Output go to the TV, and then Audio Output from the TV goes to the soundbar.
Or
From the satellite box Video Output goes to the TV and Audio Output goes to the soundbar.

No audio in dvd playback. Video works just fine. Cables connected properly. Vhs sound and audio work.


Hi,
Would you pls check the connection again that you have made between TV and DVD player..?
2xRCA (white+Red) will go to 'Audio IN 'sockets of TV in addition to '1xRCA Yellow video cable' goes to "Video IN socket 'of TV..since you have video ,probably Audio cable connected REVERSE..
if the connections are right than you must select the right source on TV ,as AV1 ,AV2 which corresponds to the cable input sockets of your TV.

When i turn my philips flattv on a message pops up.... (no video input) then turns off in 20 seconds. Unable to controll.


The TV may be turning off as a power saving precaution as it thinks it's not being used.

What are you plugging into it? No video input suggests the tv is waiting for sky or DVD player to be plugged in. Is it?
