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?

Cable box is plugged into denon's hdm1, but I can't get a picture. Hdm1 out monitor (arc) is plugged to TV hdm1 in (arc).


Power up all components. Select the HDMI 1 input on the Denon amp, and the HDMI 1 input on the TV. Additionally, run the old analog cables between the cable box and the TV. If no picture, select the input on the TV that is associated with the analog input from the cable box. You should have a picture at this point - but it will be a standard definition type. Check the settings on the cable box to change the output from "A / V" to Digital on the HDMI jack - if present. You may have better luck unplugging power / replugging in the cable box first - or calling the cable company if you can't find settings for this. Once you have the output of the cable box to HDMI, select HDMI on the TV. If you still don't have it working - try bypassing the Denon and go directly into the TV from the cable box. Try it with BOTH HDMI cables. Also - try different inputs and out puts (HDMI 2, HDMI 3, etc.). Discard any HDMI cable that fails to show video and play audio.

Connecting a passive subwoofer to a denon 2113


you need another reciever/amp to power that sub, because that denon reciever is designed for a powered sub,. if you have another old reciever/amp laying around, you can connect the sub out from the denon into an auxillary input of any old reciever/amp, (switched to that input) with speaker wires from old reciever/amp to the passive sub

My player seems not able to upscale the signal from my antennea and DVDs


Upscaling will only occur when playing DVDs. You have to use an HDMI connection from the DVD player to the tv. For upscaling of DVD's you will also have to setup the upscaling resolution in the DVD player's setup menu. Be sure to set the resolution to one that your tv will support.

If your tv does not have a HDMI input, then you will not be able to use the upscaling feature.

Upscaling will not occur on antenna signals. This is not possible because the hardware (inside DVD player) is only meant to upscale DVD video.

Again, to upscale DVDs ONLY, you will have to have an HDMI cable going from DVD player to TV, set up your upscaling options on your DVD setup menu and have a TV that has a HDMI input and is capable of recieving the upscaled resolution you have set your DVD player to.

If you have any further question regarding this, let me know!

Connect denon 1709 to my tv


I will assume that your TV is an HDTV capable unit. Since I also would assume that the Denon AV1709 is properly setup in your listening room/Home Theater. You will need to purchase one HDMI cable from the Denon to the TV input. This cable must be long enough to go from the Denon to the TV with length to spare. The more money spent on a better quality HDMI cable will pay dividends on how much better the screen will appear. On the back of the Denon is an HDMI output labeled "Monitor Out" that the new cable will go into, and the other end of the cable will go into the TV input labeled HDMI. On the remote I would search for a button labeled "Input" or "Source" and on the screen I would look for the input that would reflect the same input you put the HDMI cable into in the TV. If your TV doesn't have HDMI inputs see if it does have "Component input" on the back The information will be similar but will reflect the different Input and Outputs you may need to use. The cables will be more complicated but they are color coded just for you. Red goes to Red, Blue goes to Blue, Green Goes to Green. Enjoy Re-Post if you need further information.

We have a Denon AVR Surround Sound receiver, a Samsung HDTV, an XBox 360, an ASD-3W Denon Ipod Dock and Klipswitch speakers with a subwoofer, center channel and too bookshelf speakers. We need help...


HDMI input connect as follows:

1. Connect an HDMI cable from the Cable box to the TV/CBL HDMI input on the Denon.
2. Connect an HDMI cable from the Xbox to the DVD/HDP input on the Denon.
3. Connect an HDMI cable from the HDMI out-put on the Denon to an input on the Samsung.
You don’t have to use the optical output from these to devices since the HDMI cable allows for the transfer of both audio and video, if you have them extra use them in addition to the HDMI cable and last,

4. On front of denon after you setup and assign your optical connections, if you use them, once you select TV/CBL or DVD/HDP as a source, press the input mode button to select auto

No component output on AVR-4306


This does not work... You can only upscale the video signal with 4306; meaning you can covert s-video, component video to HDMI but can not down-convert HDMI input (coming from your HD DVD player) to Component video output. Sorry that I could not give you a solution as this is the 4306's limitation (written on the 4306 manual.).

On screen display


Try connecting to the yellow RCA monitor output on the amp and corresponding input on the TV. This works for me. You could also try the composite outputs on the amp. This is one flaw the amp has that the setup screen will not display through the HDMI connection.

Display resolution through dvi input HELP!


For the record I have a playstation 3 running to tx100 through hdmi to dvi adapter. It does all resolution no probs, including 720p,1080i and 1080p (which tx100 does do smoothly through dvi). My denon upscaling dvd player works fine too. In fact the tx100 looks totally awsome with PS3 games and Blu-ray.

Maybe your dvi lead is the wrong type (i think there are 2 types) or perhaps you could test with a differrent piece of DVI kit in case it's your pioneer causing probs? Hope this helps.

No video


I am not sure if you have gone into the Receivers Menu or not? If you have NOT! Then please try this: Go into the Receivers Menu (If you do not see the MENU on the TV you can hook up a Composite (Yellow) Cable from the Receivers Monitor Out (Yellow) and select the Input on the TV that you plug into) Look in the Menu for Inputs or In/Out Config. or Video Setup. Look for the Input that you are using for that Device. Change the Video setting to HDMI. I also recommend doing this for you Audio as well. Find the Audio Inputs and MATCH each Input to there DEVICE and CABLE (Connection) Being used. Also check in the Receiver Menu for UPSCALE or UPSCALER. Turn this on or off to see if your TV is Compatible! Hope This Helps! P.S. Check the Manual for Upscaling Capabilities NOT all Receivers upscale and route the SAME!
