Hi can u hep? i connect my hdtv connector from my x box to a hitachi plasma 42 " tv which also acts as the pc port, but get no sound?

If your television is under warranty, have the manufacturer repair or replace it for you. If your TV has more than one HDMI port, you can use an HDMI splitter to connect multiple inputs to the one port. However, if you are confident in your soldering skills, you can repair broken HDMI port, so long as the damage is only to the connector and not to the printed circuit board to which the port is soldered.

Based on what you have tried if a buzz or loud static via the speakers you have something wrong in the audio output circuit of the set--problem here is that circuit may be part of the Main board that processes all signal---a look inside---following the speaker leads back would lead you to that board.

A simple thing to do to narrow it a little (you may have done this) is with sound all the way off put your ear to the internal speaker--hear anything at all like a deep hum?

Depending on age of set and cost of the board likely bad it may or may not be a do it yourself repair.

HI
Try restarting,check that every connection that should be connected is connected.
Especially the scart connection, they have a tendency to cut out the sound or colours.
goodluck

Check software version and see if there is an upgrade, website

Replace your buffer boards they are two unit located on the right of the plasma if you are looking the plasma from behind. Do you have any sound?

Thanks,

Are you running the sound directly from the DirecTV box to the Onkyo reciever? or is it routed through the TV first? Personally if you have it routed through the TV you are losing out on true 5.1 surround. To ge that you need to have the DirecTV box connected via optical or digital output (orange connector) to your Onkyo amplifier. If you need further assistance please email me at tvtek(at)msn.com

Yes

I believe there is a Suitable port on the TV for this. Typical VGA (D-SUB) Cable will suffice same as monitor.

Sounds like a bad component on the video board. These days, TV techs just swap out boards for whole new ones.

there is no cable slot. the monitor is not a receiver. it has no tuner in it. it will need a signal from a tuner box. and that must be fed to the tv with an hdmi cable or a dvid cable for hd to work. see your manual for further information on cables. see your cable supplier for information on hd boxes available in your area. if you do not buy hd service, you will not get an hd signal. so you will see little difference from a non hd device. your dvd player may have hd capabilities, but will also need the same cable to deliver true hd signal.
the good news is that its fixable by using the right equipment.
good luck
