When i turn on the TV all that comes up is...NO SIGNAL VGA INNPUT, cant get it to do anything else

reset your laptop display connections or get a new HDMI cable

Unfortunately. the HDMI port on the M190VA does not interpret the signal from a computer. The HDMI signal from a set-top box is different than that of a computer. You need to use the VGA port and the PC audio in on the TV; if your computer doesn't have a VGA port, use a DVI to VGA adapter or other appropriate adapter. You will need a 3.5 mm audio patch cable to use the TV's speakers. See page 25 of the M190VA manual here: http://store.vizio.com/documents/downloads/hdtv/M190VA/364User%20Manual.pdf .

I wish that I had better news for you.

Most TVs will have HDMI and RCA component and composite jacks. Some TVs will also have a VGA port. Your laptop will have a VGA port. (If the laptop is fairly new, it may also have an HDMI port.)

Not all TVs will support an HDMI signal from a computer, so the VGA signal is often better. However, that limits you to SD (anything with HDCP will fail.)

Very few TVs ship with the HDMI or component cables. However, there are some vendors who do package the HDMI cable with their TV. Without knowing which exact model of TV and laptop, I can only make a few suggestions. I know that the TCP42ST30 (Plasma 42") doesn't have a VGA port.

Look at your laptop for any external monitor port. VGA ports are generally blue female ports with 15 holes (D-Sub). If your TV has a matching VGA port, get a standard VGA monitor cable.

If you have the VGA port on the laptop but not on the TV, you can try a converting from VGA to HDMI. (You may need a DVI to VGA adapter and either a DVI to HDMI cable or a DVI to HDMI adapter.) Note: this gives an analog signal (RGB format) to the TV. You'll also need to make sure that your VGA port is active (in the BIOS for some computers) and then set your computer to send the signal to the external monitor. It is best to turn off both the computer and the TV before connecting the two. Then turn on the TV and set it to the correct input before turning on the computer. (In Windows 7, I set the video signal for the external monitor by right clicking on the desktop and selecting Graphics Properties. Set the signal to the external monitor and click Apply. Then click OK (in the external monitor's screen).)

If this doesn't work, you need a VGA to component video converter. (Not a VGA to component video cable - those are for projectors that read the RGB signal.) See http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215-p1.html .

Some laptops come with an HDMI, mini-HDMI or a DisplayPort option. For the latter two, you will need the appropriate cable with that end and the HDMI connector on the other. Then connect the TV and the computer as described above. (Note: my TVs accept a computer signal at the HDMI port labeled HDMI/DVI. However, you need to make sure that your TV understands this signal. It isn't the same format as that from a set-top box. My laptop has VGA and HDMI out; the desktops have VGA, DVI and HDMI (on one).)

If you add a comment with the model of your TV and laptop, I'll be glad to give you more specific options to connect the TV and the computer.

I hope this helps.

(A DVI port is a digital video out option with ~21 pins and is usually white.)

No, a DVI to VGA adapter will not work. (The TV is looking for the digital signal from a set top box. This is different from the analog signal on the VGA cable.) You need a converter. Your best bet would be a VGA to component video converter. (I am assuming that the Sharp TV has a component video input.) This page has some examples: http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215.html?sorter=productname-en-asc . Note a VGA to component video cable will not work. The VGA to component cables are for projectors that read the RGB signal. The component video signal is YPbPr.

Connect the VGA cable to the converter and the component video cable to the TV and the converter with the computer and TV off. Turn on the TV first and set it to the component video input and then turn on the computer. Then (assuming the VGA port is enabled - adjust in the BIOS if needed) set the computer's video output to the VGA port. (On my Windows 7 laptop, this can be done by right-clicking on the desktop. Choose Graphics Properties and set the display to the external monitor or both. Click Apply and then confirm the change (on the external monitor if using the single monitor). (VGA to Composite video converters also exist if you do not have an available component video input on your TV.)

If your computer is fairly new, you may have an HDMI port. Your TV may be able to read the signal with a DVI to HDMI cable. (It depends on the TV. Not all of them will read the computer's signal on the DVI port. Check the documentation for your model. TVs without a VGA port are less likely to support this feature.)

I hope this helps.

Try changing to the right Innput on the tv:
VGA is called PC on the tv (blue computer screen cable)
make sure the Output from the tv is working and the right number is displayed
Change the size of the screen on your computer and or enable dual screen
(Right click on the desktop and klick screen resolution)
and last but not least try using an other cable

Usually when VGA or PC input selected TV come on, says NO SIGNAL, and turn itself off. After turnin on you have few seconds to change tv input.

Get a vga cable and connect it to the side of the laptop, or where you can see the vga connection then send signal to either a monitor/ tv (if they have a vga connection).

by doing this you will be able to find out if its the screen that is faulty or the graphics card.

if you cant see anything else on external screen then its either the graphics card or the laptop motherboard.

if you can view pic, then its the screen, then you can decide if its worth replacing?

If the tv powers on correctly, then recheck all wire connections (including ac cord) are in proper placement and fit. Make sure the DVD is working properly and is connected properly to the tv. Visit the tv menu and check all settings for input signal. Be sure to have the correct "input source" set on your tv.

1. Press FUNCTION repetedly until "DVD" appears in the front panel display.
2. While holding down rewind botton, press FUNCTION.
The output signal is changed to interlace format.

I think the problem is the screen resolution and size of your pc is not matching the resolution size of your tv or is not compatable at the size you have it on or you may have to change to 4:3 ratio from widescreen. In your manual it will tell you the resolution sizes that you tv uses. You would probably be better also using the VGA to DVI lead, thats if it came with the tv (it does in the UK) as it supports higher wide screen resolution, whereas VGA will only support 1024 x 768 or there abouts.
