Why won't HDMI leads work on out hitachi1080 tv

have you tried connecting ur laptop via hdmi to tv? if it works you should probably check tv settings for hdmi, if not then it is possible that the hdmi controller from tv to have some problems, i had a similar problem with a philips tv and took it to service ending up in a total replacement of motherboard and led display

If your model does not have an HDMI out connector (the maual indicates not all models do have this, you can purchase an HDMI card for your PCI express slot and add the functionality to your laptop.
There are also plenty of USB to HDMI converters that can turn your USB port into an HDMI port.
Hope this helps

Does your TV work on VGA, it maybe worthwhile getting a HDMI---VGA lead and try that as it sounds like your TV isn't working, and you've tried the obvious. Do any other HDMI devices work on your TV, like DVD HD/SAT?

The TV has HDMI, component, and DVI inputs, you will need a VGA to DVI cable to connect your laptop to the TV.

If you want to connect your blu-ray player to your tv, use the HDMI cable.
If you want to connect your cable box to your tv, I'd use component cables or get another HDMI cable.
You're right, you don't have to use your cable box to use your blu-ray player.

yes you need to connect audio out from the tv to audio in on the dvd surround. you need the red/white phono to phono leads, simply connect together and select audio (av,au) on the input selection.

check the hdmi out with another device that takes hdmi, the hdmi system works on its own from the av board side of the av board. has its own settings. then main board will have a large chip on the board and this is the hdmi control chip. these can go on there own and not afect any other part of the tv

Well, I won't take the credit of others. Many people have the same problem as you do.
In the search box on the top of this page, put in " PS3 HDMI ". The one that has the 10 solutions so far has the best answers for you.
Good Luck

Try this

1. Turn ON TV
2. Connect PS3 to TV HDMI input
3. select TV HDMI input for PS3
4. turn OFF PS3 if it is ON
5. Press and hold the [I/O]Power button until the PS3 until you get the "HDMI Detected" message.

Also, this TV has a circuit that deactivates the HDMI if the rear cover is removed. It is possible the HDMI may have been turned OFF. This is reset in the service menu of the TV.

The HDMI lead only carries the video and audio from the HTS6510/05 to the TV.

The scart carries audio and video both ways.

Re-connect the scart lead and all will be ok.

N.B. When the HTS6510 is switched on, the TV will auto-switch to the scart input. You will then need to switch the TV to HDMI to get the benefit from the DVD upscaling.
