I recently bough a used 40in sony trinitron xbr. i have the DVI to HDMI cable but wether its my laptop or xbox the sound wont come through the tv at all. any suggestions?

HDMI-1, according to the manaul, supports a DVI input only. DVI does not carry an audio signal. You need to use the DVI audio in if you are using HDMI-1

Since the TV accepts HD signals only via DVI and component inputs, the only logical way is to use the "Xbox 360 Component HD AV Cable" as show in the link below:

How to hook up your Xbox 360 or Xbox 360 to TV

The TV will not accept a VGA input. A cable converting HDMI to DVI would also require that you break out the L + R audio channels, too. The one I mentioned above does this all for you with no degradation in video signals.

Refer its user manual for details. If you do not have the user manual. try the site linked here, and download it for free. www.retrevo.com/

Is the Xbox one not picking up the tv if not try an HDMI cable. They mostly cost $15

Use the laptop's VGA output to plug into your TV's DVI.

you need to reprogram channels. Itll only pick up 3 if you are still using coaxial cable from box, or change input to DVI/HDMI, aux, etc.

sounds like you have some cold solder or bad joints,power section, inspect it ,with the back off, but be carefull.........i had one that did that...bad connection in solder joint...had to resolder,if you have to resolder,make sure it is unpluged.hope this helped....

I've just recently connected my old 32" Sony KV-32HS510 to my HP G60 Laptop via an HDMI (laptop) to DVI HDTV port(TV) with a cable.

I'm running Windows Vista on my laptop with the nVidia software. Once I've plugged in the TV to the HDMI port, the software initializes (recognizes the TV) and then I can select it as my second 'monitor' in the nVidia control panel.

I found I had to tinker with the resolution settings in the nVidia program to find an optimal resolution where the sides of the screen weren't 'cut off' by the TV.. I finally ended up with the resolution 1152x768 (I believe). It might be different for everybody, as I'm told Vista might do things differently than XP... But you should be able to tinker with the resolution settings and adjust the screen size...

(hope this helps with the second post - above)

DVI = HDMI without the audio connectors. So basically you need to connect your audio in some different way, PS3s allow you to keep your video signal as HDMI and change the Audio signal to component, so that is one way or doing it, not sure if the blue ray players allow you to do this though.

Yes. As long as your PC has an HDMI port as well (or at least a DVI port and a DVI-to-HMDI converter dongle).
