Cant access input jacks

The 27" TV uses the same instructions as the 20", and I found the manual for you at the link below. Answering your question directly, here is the section of the instructions about changing input:
-----
Changing the TV's Input Normally, your TV displays the signal coming through the antenna terminal. However, if you've connected another component to your TV(such as a VCR & DVD) using the Video/Audio input,you will want to be able to view the signal from the component.To do this, you will need to switch from the ' TV ' input to the 'AV1-AV3, CVI' Input, as follows. 1 With the TV on, press the MENU button twice, then " Set-Up " menu will appear. 2 Use the WCHV buttons to select " Input ". 3 Press the CVOLB buttons to change the input source from ' TV ' to 'AV1, AV2, AV3, CVI'. 4 Wait 20 seconds, or press DISPLAY button or MENU button to return to normal TV viewing. * CVI means the Component Video Input (Y/ PB/ PR) from the DVD player etc.* Users can also select these input modes with the TV/AV button or the INPUT button on theremote controller. * On the AV1 mode , if you connect the S-VHS jack to your TV, "AV1" is changed to "S-VIDEO".

The link to the manual is below.

The Remote for the TV set itself should have either a input or source button on it (some call it tv/video) If you are hooked to a set with more than one set of the jacks they will be labeled video 1 or 2 etc.

simply with the remote for the tv change inputs until you either see the picture or the display matches the location you plugged into.

Your DVD audio is sent directly to your receiver - not to you TV. That's why you can hear the audio on your stereo. The TV audio is not being sent anywhere - it is "stuck" in the TV and is amplified and sent to the TV speakers. Since the TV speakers are off, you don't hear anything. In order to listen to the TV audio on the stereo system's speakers, you need to send it to the receiver.

You need to have a pair (left + right signals) of audio cables (assuming you wish to listen to stereo sound) from the TV's Audio Output jacks to a pair of Audio Input jacks on the receiver / amplifier. You can use any unused input - CD, Video, Tape, Sat, etc. If you use Tape or Sat audio inputs, when you wish to listen to the TV audio, you must select the Tape or Sat input on the receiver.

Do not send more than one signal to a set of inputs on the receiver. Typically, a CD, DVD and Sat inputs offer two or more of the following types 1) Analog audio. These are the older RCA jacks that have been around since the beginning and require separate cables for left and right channels. 2) Optical inputs. This is the newer digital interface that provides for Dolby Digital (and others) format sound over a single fiber optic cable. 3) Coaxial inputs. This jacks looks like an RCA jack, but usually has an Orange ring - instead of the Red & White rings that analog RCA jacks have. They use a single coaxial cable. 4) HDMI input. This jacks carries both digital video and digital audio signals. If you are using an Optical input for the DVD on the receiver, do not use any other unused analog or digital inputs associated with the DVD to "piggyback" another device like a CD , VHS tape, etc.

I hope this helps and good luck! Please rate my reply. Thank you.

Connect the composite video RCA (yellow) cable output of the DVD player to the TV's video input RCA (yellow jack). Connect the red and white RCA cable from the DVD players audio output to the TV's audio input (red and white jacks). Select the source input from the TV's control panel - if it has an input selector switch, set it to select the video source from the front panel input jacks if you connected the three cables - yellow, red and white on the front of the set. Or, change the channel to receive the video auxiliary input source instead of the broadcast station.

There are lots of inputs on the back behind the cover. Three inputs (1, 2, 3) have an S-video, composite video (A/V) and component video jacks. The cover will come off if you press the two top hook at the top of the cover. Then rotate the cover towards you. There are also a DVI-D port and 2 coax (antenna in) jack. The tuners included are for NTSC (analog OTA) and CATV (analog cable). The front of the PC (VGA) and a S-video or composite (A/V) video input (called Input 4).

Composite and component video jacks are all RCA jacks (as are the associated audio jacks for the input). Composite cables uses three RCA plugs on each end - yellow for video, red and white for Right and Left audio. Component video cables have three plugs on each end that just carry video (red, blue and green); the audio is wired separately with just 2 RCA red/white plugs. Match your colors from the device out to the TV input.

Changing inputs can be done with the remote or the input button on the top of the TV. The input button is to the left of the power and Main Power buttons.

Connecting your game system, cable system and all will depend on the units. For the best picture, use component video cables for mose set top box. Some cable boxes have a DVI port - use that if the box has that option. If they do not have component video out, then use composite or S-video cables.

The owner's manual is available from Sharp as a pdf: http://www.sharpusa.com/CustomerSupport/ProductDownloads.aspx?downloadtype=ownersmanual . Use the drop down menus as follows > LCD TV, Model not listed, LC-30HV4U then click Search. The picture of the inputs are on page 10.

I hope this helps.

Hello,

The only computer (or laptop) connection that carries both video and sound is HDMI. If you do not have a HDMI/DVI connector on the back of your computer, then you will have to use the VGA-composite or s-video connectors to display your PC's output on an external monitor like an LCD TV.

On both my HP and Dell laptops the display settings (Start/Control Panel/Personalize/Display Settings) allow two modes - single or dual monitor mode. Single monitor mode allows me to switch between any one of three possible video outputs - VGA-composite, S-Video or laptop screen, or a split-desktop (display spread over two separate monitors). Dual monitor mode allows the same display on any two of three possible video outputs.

Switching is performed using the fn keys on the keyboard (fn key plus the F2, F8, etc. function key with the display marking). You guys use single monitor mode until you figure out what your are doing. Select VGA-composite or S-Video.

Non-HDMI sound to your TV monitor or sound system must be obtained from your laptop's Headphone or S/PDIF jacks. Headphone is stereo and S/PDIF is 5.1 surround sound. Headphone is electrical, but S/PDIF may be electrical or optical (laser light). You must set the sound jack that you intend to use as the default on the PC control panel (Start/Control Panel/Sound).

None of these connectors is two-way in the context of an LCD monitor - your PC cannot record a TV picture or sound from the external monitor. To accomplish this you must purchase a video converter box that converts cable TV or video + sound inputs to USB format usable by your laptop. Do this and you can turn your laptop into a Tivo recorder/DVD burner using Beyond TV, Sage TV or a variety of other software packages.
Please let me know if you have any further questions or concerns.
Thanks.

If you have the converter connected to the recorder by composite or s-video(line inputs), you will need to specify which jacks from within the setup menu of the recorder. There are 2 sets of line inputs into the recorder, so you have to select the right ones. They are called L-1 and L-2. The L-1 jacks are in the rear and the L-2 jacks are in the front. The channel selection should also be on L-1 or L-2. If you are using the
RF input(fat cable) to the recorder, you should have the recorder on the channel number that matches the output of the converter (channel 3 or 4). The converter RF output is selected by a switch in back of the converter or by the setup menu of the converter.

Menu path for setting L-1 or L-2 inputs:
Setup > General Setting > Video > Video Input > L-1 or L-2 > Video In or S-Video In

firstly try that tv to a different tv
if this works
then check your tv av connections in side tv
also check cables continuity
if this fails buy a AV/ RF converter, have your AV be connected to a converter, and let your output be RF feed to a tv, RF input, so instead of using AV on your tv you will be using RFchannel mode

Make sure the S-video and the composite cable are not plugged in it the same time from the Denon of at the Plasma

Hello gerrydav, What might be happenening is the refresh rate for your blu-ray is offsync for your preferred display. You should be able to change it by plugging it into another TV and playing around with the settings. If you have further problems please feel free to post again.
Please post what you do and how you did it. I look forward to your posts.
