Question about LG 42PX5D 42 in. Plasma HDTV

1 Answer

Unable to display HDMI Input

Have recently upgraded my amp to a Denon AVR1908 that is "upscaling" capable. Plugged HDMI cable into Amp HDMI out & into LG's HDMI input. DVD & cable are correctly plugged into the amp & must be to get picture & audio at Comp & AV. Can get display through Component & AV but when HDMI on the set is selected - no signal. Taken all the kit back to the HiFi shop who tested my Amp & HDMI cable and all checked out OK on their gear. Their techs said it must be my monitor though on reviewing the LG manual could not identify anything other than a faulty monitor. Plugged in to Amp HDMI out to LG 42PX5D. Is there a way of re-booting the TV or do I have a fault. The set is 18 months old and this is the first time the HDMI input has been used.

    No HDMI cables other than between the monitor and the receiver / amp. The amp is "upscaling capable" and the amp manual confirms that this the case. The dealer I purchased the amp from re-tested the amp and proved this to me on one of their monitors (a Pioneer) and worked fine. I have since had an LG tech look at the set up and he has said I definitely have an issue with the HDMI on the monitor. Interestingly, if I change the setting of HDMI in the amp to from RGB Normal to RGB Enhanced, the LG's display changes from "No signal" to "Invalid Signal". I await the removal & repair of the set. Unfortunately, the set is out of warranty and the problem has most likely existed since the set was new. Puts me off the thought of buying another LG. Thanks for your effort.

    Have new Sony 350 blu-ray player and can get no signal through the HDMI lead. Bought really expensive 1.3v leads but no joy. Will work on SKY HD though. Luckily I have a five year guarantee with John Lewis and they will get the call to fix it. Have E-Mailed LG assistance but yet to get a reply.

    I have an LG 32LX2R-ZE. It only has 1 HDMI input so I have been using an HDMI splitter. My Sky HD box and PC are both plugged into the splitter using HDMI cables then an HDMI cable into the TV. Everything was working ok but now when I switch to the PC the TV displays 'No signal'. The strange thing is the Sky HD still works. All cables are tested and are fine. I also checked the PC on a different TV and also working fine. My mate plugged his Laptop into my TV using HDMI cable but again no signal. It must be a fault with my HDMI input on the TV?

How do i connect my DVD to TV

You have a few options that depend on the types of OUTPUT jacks you have on your DVD player & the types of INPUT jacks that are on your TV. If both devices have HDMI capabilities, using that kind of cable is the easiest & best sounding/looking of all the options. If you have COMPONENT jacks (red,blue & green cords), just connect the appropriate color to each end. *Note: to get audio while using COMPONENT cables, you must also use the red & white connectors from the audio OUT jack on the DVD & connect them to the red & white audio IN jacks on the TV. The other connection method is by using the COMPOSITE cables (red & white for audio, yellow for video)

HDMI input says "mode not compatible"

If your Playstation is putting out the signal in 1080p then try changing it to 1080i and see if that works. Not all TVs are compatible with 1080p.

How do you enable the pioneer plasma pdp ro6fe HDMI settings? My HDMI input options do not currently allow selection & adustment

just plug in the HDMI cable from what ever equipment your using,then switch it on, put the other end into the back of the tv, take out any scart cables you have plugged in, just for now.
then find your AV source button on your remote, press it until it says HDMI.
the chances are,if it flickers or wont show, then you'll need to hook up the external equipment by scart cable & go into the picture settings & change it to a lower rez. (The tv wont be the problem)
i can't help you any more because you haven't said what it is your trying to do or hook up.....SKY BOX, DVD PLAYER, GAMES CONSOLE...e.t.c.
Or what make of TV it is.....

I plugged in the normal 3 Video inputs and it still doesn't work.

More info is needed, please. When you say 3 video inputs, what are you referring to? I believe the Sanyo has the HDMI, RGB/YPbPr component video, S-video component, RCA composite video and Coaxial connections, though I'm not sure how many of each. So lets start with the best quality to least.

HDMI: This is one cable that provides both audio & video and produces the best picture quality. It comes in different lengths and is a wide, flat connection. A must for 1080p resolution signals.

Component video, RGB or YPbPr analog component cables: 5 separate RCA cables, 3 of which are video that separate the video signal & 2 audio cables. The 3 video cables are generally red, green and blue (RGB) or marked individually with the letters Y, Pb/Cb & Pr/Cr . The audio cables are red & white. You may see these on the back of DVD players often. They will carry a signal up to 1080i but not 1080p.

S-video component: One cable for video, it is a round connection with several pins in it and will only plug in one way. You must use 2 RCA cables for audio with this cable, red & white again.

Composite video: 3 separate cables; Red, White & Yellow. Red & White are audio, left and right while yellow is video.

And finally there is coaxial which it the cable that is identical to the cable from the pole/ cable box or your dish. It is the poorest quality.

What can happen is you are using 3 standard RCA cables and have them plugged into the component input & they will not carry the signal, or one end in component input and the other end in the composite output or vice versa. Another is that you have the wrong input selected on the menu. Check all your cables and connections, plus the input you have selected on the TV itself.

you can use a scart lead and just select av1/av2 depending on which one you have plugged in or if your dvd supports hd upscaling you can use an hdmi cable and select hdmi 1 on your tv menu input.

My Philips 42PFL3603D/27 that does not connect to hdmi device.

At the rear or side of the PC there should be either or both of a 15 Pin DIN Plug, HDMI socket. or a Yellow RCA or 4 -7 pin DIN. Now IF these are present then YES you can connect to a TV. Now some TV's have a connector a DB15 MALE, so that the cable from the PC to the TV, is DB15. this plugs in directly, with appropriate DB15 cable. This, however, will ONLY take the VIDEO to the TV, Audio is delivered via the "Audio Out" Jack on PC, and Plugged into the AV Sockets on the TV, with a dual cored coaxial cable, they are Red & White. Some PC's also have a Yellow RCA Connector, OR a 4 -7 Pin DIN Socket, that requires a Special Adapter Cable (That generally came with the unit, and are colored and marked as to output) to use, for Video/Audio Out to TV. This signal is Composite or SVHS Video & Stereo Out. This connects up TO the TV's Composite/SVHS input Jacks and the Red & White Audio IN, RCA Jacks, &/or DIN SVHS socket.
First you need to know if your PC can output to a TV. Then you need to get the adapter & cables that connect the PC to the TV. Then you need the correct TV drivers installed for your video card. When they are all installed, you need to "Enable" that Monitors, the TV's, Desktop. You need to set either a "Cloned" display or "Spanned, Extended Desktop". Go to "Display Settings" Now ensure the TV/Monitor connected has the correct input/output display settings. Adjust the screens resolution via the resoloution "Slider", it is best to start with, 800x600 32 bit color. or even lower. and once working OK, THEN increase to max resolution, your TV can handle, find out from manual. Once it is all connected up. It should all just work great. Now, from then on, &, to get it to work every-time, the process is. Turn everything OFF. Connect the leads between PC & TV, Turn the TV, ON. Then, startup the PC up. It should "Detect" that it has TWO "Monitors" ie: One Monitor & One TV/Monitor, & you should see your desktop appear after a bit. Now you have screen 1 & screens 2. Now, if you are using "Cloned" mode, then whatever is displayed on the Master monitor, will be displayed on the TV. If you used Spanned, mode, in this mode, however, you will have to."Drag" the Video window, over to the TV, and it is though, you have one "Big Desktop". Now IF using Nvidia or ATI then BOTH of those have thier OWN, Control Panel, this, all then can make it all a lot easier to do it. So I would suggest that this method be used. But if you get stuck, or just want to do it by hand, then the the "By Hand" method is the only way.There is a great program called MultiMon, this allows great control over dual displays, and is well worth installing.

How to get a high definition Picture??

Hi, first of all you need a high definition source. I'm not sure if your cable box is HD but lets take it as an example. The component leads which you are using isn't 'true' HD video quality, what you need is a hdmi cable from your source to your TV.

Your cable box maybe HD with a HDMI output, if it is then you need the lead to come out of the cable box into your tv's HDMI input using a HDMI lead. Then you switch your TV's source to the HDMI input and it then should be producing a HD quality picture, but to truly get the full HD experience you may want to subscripe to a HD channel or purchase a blueray player becasue most cable TV channels are upscaled to HD and the definition is not as good as on a blue ray disc or a true HD channel.

So in conclusion the cable and input you are using is not designed for HD input. I believe your TV is HD, check for HDMI inputs or DVI inputs.

Hope this explains your problem
