Everytime we turn out telly on we have to press AV2 on the remote control and when we try to watch DVD no picture comes out. We wanted to Configure it but there's no Configuration on the menu list and we tried to reset it but still nothing happened. Can you help us please? Thanks.

Re: Hitachi 42PD8700 U

Switch on the dvd player so it's playing, then do a new master tune. press the dtt/tv button so you are watching the internal freeview system, then press menu, then go to installation, and re-install all channels. the tv will then detect your dvd player in the intial set up/tune mode.

hope this helps..

Hi Anonymous,

Please press SOURCE key on the remote, source menu will appear on the screen. Select the source like AV1 or AV2 to which you have connected the DVD player through AV cords.

Happy viewing.

Trouble trying to connect my dvd player and set it up to my new 42 " L cd lost instructions!

Hi there,
You will need to determine if your DVD player is HDMI or Scart. If you connect it via a scart lead, then it should automatically turn on when you power it up, if not it will be located on your tv under the appropriate source/input label, ie AV1/AV2, or SCART.
If you are using a HDMI lead, then you will have to turn it over yourself, as HDMI does not support switching control. To do this, locate the input button on your remote (sometimes labled source) and press it until you can select the correct HDMI input using either the directional buttons, or by repeatedly pressing the input button.
Hope this helps

I turn on tv. There is sound but no video.

hi, if you have a device plugged into the telly that gives you the picture such as sky or cable then the best thing to do is disconnect this device from the back of your telly then switch the telly and this device off at the mains, then re-fit all the cables making sure they are connected properly then switch it all on.

now check if you have sound also make sure the tells is on the correct input for that decice and also make sure the mute button has not been pressed on the telly remote or on the remote of the device you use to watch telly, if after doing all that it still dont work then the chances are something has blown on the amp in the telly.

make sure you double check all the leads going into the telly to rule out a faulty lead causing you the problems

When i turn the tv on i get sound but just a black screen

Try pressing the menu button on the remote to see if the menu comes up.

If it does it's possible the light and colour have been turned right down, find the option on the menu and turn it up.

Also check no cables are unplugged at the back of the tv, picture is usually yellow make sure it's in tight. Check other end as well so sky box or DVD player.

If you're using an AV port on your tv try using a different one, so switch form AV1 to AV2.

Sound but no picture on TV

Try hooking your components up to the "AV1" and "AV2" jacks on the TV. I experienced this when hooking up my DVD and VCR (movies of my kids so kept it around). I hooked one to AV1 jacks and one to COMPONENT jacks and had the same result you're describing. Hope this helps.

hi, what you need to do is find the source button or av button on your remote control as it sounds like its changed source this causing your problem. As you probably know your telly has many inputs for dvd vcr cable or sky but these plug into one of the inputs in the back of telly. Usually the problem is just that your on the wrong input channel like av1 instead of av2 or rgb their are many inputs so you might need to press this button 2 or 3 times till you get the right channel, i dont mean 1 to 9 channels i mean input channel like rf input or av input. This depends on what your getting the signal from if its cable and its plugged in via scart lead then it will be an av input but you might have av1 av2 av3 av4 this depends on your telly.
If your still having problems then give me a shout back ok best to check all the leads are in the telly correct as this will cause the problem your having ok.
Let me know how you get on ok or if you need further help
