Is there display drivers available for my NEX Plasma TV model PXT-42SX1B. I have a Computer that has a HDMI output which I can connect to my TV, but have not been able to correctly setup the display resolution, and therefore I'm loosing some of the display output. Any help would be appreciated. Thanks, John.

Best way to connect a computer to a TV is with an HDMI cable. If your computer doesn't have an HDMI output, you can get a USB dongle with an HDMI connector.

For example, if you have your notebook computer connected to an LCD TV and/or surround sound speakers with a high-definition multimedia interface (HDMI) cable as part of a home theater system, you may encounter some common HDMI display and/or sound issues such as the following: If you are experiencing one of the following issues, click the link to go directly to a section of this document for a resolution.

Your tv is a 2008 model, legacy 3d tv and requires a lot more than a current 3d HDTV does to view 3d. Today with a current 3d HDTV, Normally you only need a 3d source like a 3d Bluray movie and 3d glasses from Samsung and a HDMI cable connection from bluray player to HDTV. See below for your TV. You need a PC and IR emitter and Samsung 3d glasses plus user selected options on the tv.
Samsung 3-D Ready HDTV How do Samsung 3-D Ready HDTVs work?
Samsung 3-D Ready HDTVs are enabled by Digital Light Processing (DLP(R)) or Plasma Display Panel (PDP) engines that are capable of very fast refresh rates (120Hz). The inherent speed of these display technologies enables high quality stereoscopic 3-D by alternatively displaying left and right eye images. The display is synchronised with 3-D shutter glasses to provide the observer with a vivid perception of depth.
How do I connect my PC to a Samsung 3-D Ready HDTV?
The DVI output from the PC's graphics card must be connected to the TV's 3-D compatible HDMI port using a DVI-to-HDMI cable (or a HDMI cable plus a DVI to HDMI adaptor).
Alternatively, some newer graphics cards have a HDMI port instead of a DVI port. In this case, simply use a HDMI cable to connect the PC directly to the TV.
On all models, the 3-D compatible HDMI port is identified by the letters "DVI". (eg, "HDMI 3/DVI IN" or "HDMI 1/DVI IN")
What other equipment do I need to enjoy 3-D on my 3-D Ready HDTV?

• Windows PC with DVI output
• Compatible 3-D Shutter glasses and IR emitter with VESA compatible sync connector

How do I connect the IR emitter to the 3-D TV to support wireless 3-D shutter glasses?
The IR emitter should be connected to the "3D SYNC OUT" socket. The emitter should be placed on top of the TV with the LEDs facing towards the room. How do I turn the TV into 3-D mode?
Ensure that the TV source is set to "HDMI 3/DVI" (or "HDMI 1/DVI" for 720p models).
Plasma HDTVs Press the Tools button and select 3D Effect. Update from Off to Mode1.

The audio from the hdmi out on your computer is turned off. Try connecting another device such as a dvd player to the hdmi input on your tv . If audio works on tv then you know no audio is not available from the hdmi output on you computer.

It sounds like ze power supply blew when it was being turned off. This seems to be typical of plasmas. Bad power supplys wont let the tv come on and will result in no lights coming on. Since there R no lights coming on, I would suspect the power supply first, followed by the power control board,. and circuit board. It may cost anywhere from $250 to $500 to fix.

Try all of your HDMI inputs, one may be rated at the correct voltage to be able to display the video. The offical part that Panasonic was giving for this was PDPHDMIKIT, its basically a HDMI extender that regulates the voltage. The part is still available online, try partstore.com or andrews-electronics.

Step 1
Shutdown your computer and look at the rear of the case to determine the type of video connections that your machine has. Nearly all computers will have the standard 15-pin VGA output port. In addition, you may also find that your computer has an S-video port, an RCA composite video port, a set of three component RCA video outputs or perhaps even an HDMI output port.
Step 2Determine the types of video inputs that are available on your plasma TV. There should be a standard RCA composite input, a three-jack RCA component input and an S-video input. In addition, you may also find a 15-pin VGA input, a DVI input or an HDMI input. Step 3 Select which type of connection you will use. HDMI and DVI represent the highest-quality connections, followed by VGA, Component, S-video, and composite. If your computer has only a VGA output and you will not using it solely to drive the plasma TV, you may want to invest in a video card upgrade. Most new video cards will offer dual monitor connections and possibly a separate TV connection. The first monitor connection is intended for the main computer monitor, and the second monitor connection, or the TV output, can be used for either a second monitor or a TV. Depending on the card, the TV output may be DVI, HDMI, component, S-video or composite. Step 4Purchase a video cable long enough to reach from your PC’s video output to your plasma TV. If the distance is over ten feet, you may want to invest in high-quality cables to ensure that the plasma TV receives a clean signal for the best possible picture. Cables over thirty feet in length, depending on the connection type, may result in poor video performance. Step 5Set your computer’s screen resolution to something that your plasma TV can accept, using the “Display” settings in the “Control Panel” in Windows. Refer to the owner’s manual of your plasma TV for the supported resolution and refresh rate. If you are using the S-video, composite or component outputs on your computer, this step may not be necessary. Step 6Connect your PC to your plasma TV using the appropriate cable. Start the computer up and it should recognize the attached display. In the “Display” settings, you will need to configure how the plasma TV is used if it is attached a second display. Most video cards support “Clone” or “Mirror” mode, which displays the same content on both displays. In addition, there is the “Extended” mode, where the second display will operate independently, and windows can be dragged from one screen to the other. If your plasma TV is the only monitor for the computer, you will not to configure the multiple display modes. Step 7Connect a cable from the sound output of your PC to your plasma TV using the appropriate audio adapters. Then relax on the couch and enjoy your videos on the big screen.
