Your problem is in the streaming player. It is not keeping up and when an HDMI loses connection it will not auto find it again. To verify this take the Panasonic out of the loop and see if this fixes it. I love HDMI but it is touchy

There are generally three HDMI slots at the back panel of an HD TV. Make sure you have connected the PS3 and the Apple TV in two separate slots. Sound will work because you must have hooked it up in Audio IN at the back or if you have connected the red and white audio cables in the front panel , the audio will work only on the camera setting on your TV

I have run into this issue alot. I believe its because of a older version of HDMI 1.1. Quick solution is to hookup the cable box with component cables(yprpb) to utilize the HD picture still and then do some research to see if Mitsubishi has a firmware update on your particular model.

2My Mitsubishi WD52725 displays a blue screen suggesting to check my inputs and says signal is invalid..checked all the connections and all is good there..any suggestions? Thanks in advance, Nick


What is your input source and which input cable type? If the source is a PC using a VGA cable, what resolution is the computer sending? 480x640. 800x600, 1024x768, 720x1280 (EIA standard) all at 60Hz are known to work but other modes might not.

If you are using a PC to the HDMI port, it will not work. The only HDMI ports that can connect to a computer will be listed as HDMI/DVI and this TV doesn't have that type of HDMI port.

If you are using any other input source, check try another source or channel. (One of my TVs intermittently finds a digital channel 25-9 and gives that message. We have no clue what station is being found but all the other channels are fine.)

I hope this helps.

Please post the Brand/Model of you cable box and that of your TV so I can provide you with an answer that is more accurate than a guess.
The guess is, since we are talking about HD I will assume that your cable box has an HDMI connector and you have also an HDTV with HDMI connector somewhere in the back. In that case you will need an HDMI cable and that will connect both Audio and Video signal. Then you just set your input source selector on your HDTV to HDMI (if multiple select the number of the one where you connected the cable box), and you should be getting picture and sound.
Now, if your HDTV has no HDMI input then it will be very likely that you will have to use a Component cable that is ONLY for the "video" signal and looks like 3 RCA connectors color coded as Red, Blue, and Green. You will need to get and additional cable to feed the "audio" signal from the cable box to the HDTV using a stereo cable with RCA connectors which are usually color coded as RED and WHITE.
Note: This setup although better than nothing, is somewhat defying the purpose of having HD. The signal in Component connections are analog (although of better quality than Composite i.e. the old single video cable color coded as Yellow). The analog signal is limited by design and will get you only so far in your HD experience. The HD signal is digital and will yield the highest quality in both audio and video.
Assuming you are paying extra for channels that are HD then it would be worth it to do some more research or ask for help to one of your savviest friends so you can get the best gear and results with the least expense ;)
In all cases you should be able to see the programs and hear in stereo, your experience will vary as: - Your video signal may be a 480p instead of getting a higher 720p or 1080i. - your audio signal although some movies are available in 5.1 surround, not having a surround system will just give you the stereo sound from the TV.
Either way is your call how you want to experience your media... if you like to read more on the subject a quick start could be the TV glossary at crutchfield for instance:

Tv goes off, then comes on, and volume goes to max


OMG! Verizon Fios at it again with changing boxes! Well let me tell you if you do not loose signal on a DVD using these same inputs ITS NOT YOUR TV!

Whats going on is further into Verizon system you loosing the signal from the VDSL slam outside in the pill box. This thing will need to be replaced and they are going to blame your TV until you just give up and buy a new TV only to figure out its not your TV.

1. Call them back
2. tell them to check there network
3. if that dont work tell them to check it again
4. if you have HDMI use that instead of the scart connections.

I hope you have luck with Verizon Fios there internet rules but there TV service is sub par!

Thanks

When ever the picture freezes intermittendly the problem is usually poor connection on the signal line (antenna or connection on tv) or poor reception. Could be the tuner if the tv has one.To eliminate the tuner possibility try anther tv set if possible.
If you still cannot figure out the problem,let me know what kind of set up you have connected to your tv set.
Do you have a satellite or cable box and if you have splitters.

We are having the same problem. We have 2 DVD players with up-converter to 1080i and 1080p. Both DVD work fine (one Sony and one Samsung) with our Samsung LN-T4053H upstairs, never intermittent.

LN40A530 downstairs is having "Searching for Signal" problem. Took it back to Sears got a new one, problem followed. Something is wrong with this LN40A530. Perhaps firmware update is needed.

You need a audio cable for sound. HDMI cable is only for picture. I use the comp 1 plugs myself, better picture. I found with my TV that the HDMI cable is only good if you have a digital box for it. You can also use the plug to hook your computer to off your graphics card and watch downloaded movies on.
