Question about Televison & Video

Open Question

Panasonic TH-42PX25 Plasma. Suddenly lost all the AV inputs. Video 1, 2 & 3. Have Audio & video through HDMI & Component outputs, but not having an HD DVD player or satellite receiver I can no longer see anything. Can use an Xbox through component or HDMI. Sound is perfect through those 3 outputs, but it is simply a black screen. I've seen other posts with this issue as well, but have never seen a solid response. Is it simply the AV input board TNPH07163A? I took that board out & saw no burns or evidence of failure, but I don't see what else it could be.

Usually when you have a red tint when using the component input i'ts because the wires are switched on one end or one of the 3 video wires is bad. See if blue and green are switched.I see this all the time. Is your picture grainy on all input?

SOURCE: Panasonic PT-AX100E projector 'seeing' no

You need to do a simple test: find another dvd player that you know it works thru the Composite (video/yellow) connector and connect it to your projector. If even this one doesn't works then it's a defect in the AV module on the mainboard - when you changed the bulb a static or a surge was generated and it fried the AV processor.
Sorry, this projector is effectively dead: the only way to fix that is to replace the mainboard and a new replacement one plus the labor to install it would cost you almost as much as a new projector. But, if you're lucky, you might find a second one at a repair shop or online so you should do a thorough search before selling it for parts.

    I wanted to connect hp dv 4 1275 laptop with sanyo tv with hdmi and 3 rca .but its not working .tried everything din work.

    You MUST install HDM IDrivers for your Video Card & MotherBoard. You can only use HDMI, OR Component, but NOT BOTH. Sometimes HDMI, requires an AUDIO OUT Cable, this is the Red & White, AV Stereo input.
    OR you use COMPOSITE which is YELLOW, Video, now AUDIO, is Red & White.
    COMPONENT, you use, Red, Blue, Green, (ALL VIDEO) PLUS you need the Stereo AV AUDIO too, Red & White.
    HDMI, should supply BOTH, but as related sometimes you need the Audio red & White AV, inputs & Outputs.
    ALL Cables go color to color.

    1080P video via HDMI generates awful interference

    Your Plasma's native resolution is 720P. Go into the Blu Ray's output setup. you can choose 480p 480i 720p 1080i and 1080p. Set it for 720p that should clear up the issue.You may have to run Component directly to the TV since you only have 1 HDMI input and you can run Digital coax or optical to your AV receiver for audio. On a 50" TV the difference between 720p and 1080p using "GOOD" cables cannot be seen by the human eye. Above 50, yes it is noticeable.
    Hope this helps.

    Sound but no picture

    Your player has several outputs and you might want to start with the basic Video Audo Left Right output first.

    Set your with your plazma to see if you can change the input types to accept the video and audio input which will probably be labeled AV 1, AV 2 and so on.

    My guess is that you have it set for Component Red Blue Green which his a high def (just before HTMI) and requires a separate audio cable. Your player, depending on the age of the unit, probably will not have Red Blue Green picture output.

    Next if you have an HTMI output from your player hook that to your Plazma in the HDMI 1 position and select it on the TV's setting. Audio and Video are both carried in the HDMI cable.

    Good luck, my name is Eric Kirkhuff

    How to conect a pc to a panasonic plasma th50px75u?

    Panasonic didn't make it a simple matter to connect a computer to this TV since they didn't include a VGA input connector. You can still do it, but it will require some adapters or changes to your PC.

    If you're using a laptop, you have two options. If the laptop offers an s-video output, you can use a suitable cable from there to one of the set's s-video inputs. If there's no s-video output, the other option is to purchase a VGA-to-component breakout cable, available at a number of online vendors (search with Google). This cable has the VGA connector to the computer on one end, and 3 RCA plugs at the other end. You would use this cable into one of the set's component video inputs.

    With a desktop PC, you can still use one of those two options. In addition, there may be a DVI video output connector available as well. This is not common on computers with integrated video, but is frequently found on many newer expansion video cards. If your computer has this connector (or you install a new video card with one), you can use a DVI-to-HDMI adapter and connect an HDMI cable to one of the set's HDMI inputs. Many video cards with DVI outputs include one of these adapters already.

    So while it's not going to be simple, it's certainly possible to connect your PC to this TV.

    Some where on the back, bottom or sides of your plasma tv you will find input jacks for the audio and video. You must know what type of inputs you want to use.
    Most have have 4 types

    HDMI (audio and video signal combined)
    Component (red, blue, green RCA jacks for video only)
    Composite (yellow RCA jack for video only)
    S-video ( larger round black jack with video only)

    The Panasonic should have all of those also. I am certain it has HDMI and Component.

    Connect the HDMI cable into the output HDMI jack from the Panasonic into the HDMI input jack on the TV.

    Then using your remote for the TV make sure you select the HDMI input for viewing.

    If you use any of the other video outputs on the Panasonic just connect it to the same type of input jack on the TV. Once again check the owners manual for more detailed instruction if you need them.

    You must always be sure to have the proper input selected on the TV to be able to view it.

    You can also respond back with more questions if you have any.
    I am happy to help.

    TV ranking

    Hi. You could look up reviews. I personally usually never offer advice on choices, because what I like, may not be what you like..its a matter of personal preference. But in this particular case, I'd go for Panasonic. Why? Better features, better service, easier availability of parts, and better resolution.Plus some nice features. If this answers your question, PLEASE don't forget to rate as fixed. I'd really appreciate it. Enjoy your new tube!!!
