Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

I am receiving a CABLE NOT CONNECTED error when I connect my vga monitor to my laptop using an VGA to HDMI cable


If you actually have a cable with HDMI on one end and VGA on the other, it will probably not work. HDMI uses a digital signal and VGA uses an Analog signal, there needs to be some circuitry somewhere that handles the conversion. You are probably getting Cable Not Connected because the monitor is scanning for an Analog signal and not recognising the digital signal coming in over the VGA port.

Can I connect my Asus Eee PC 1015PE to my HDMI tv (tv does NOT have VGA port)?


Maybe. You could try a USB to HDMI adapter, like this: http://sewelldirect.com/articles/USB-to-HDMI.aspx . These are fine for some uses but not generally for gaming. I'm not sure this works with Win7 Starter (due to driver issues).
Another option is a VGA to HDMI (analog to digital) converter. An example is http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10114&cs_id=1011404&p_id=6191&seq=1&format=2#description . Note: the VGA output is a 480 (SD) signal; some issues may occur. Also you need to make sure that the refresh rate for the computer is set to 60Hz. (On some ultrabooks, the VGA port is disabled for power-savings. In that case, you may need to enable it in the BIOS as well as setting the video output.) Then the TV will be the only monitor while it is connected to the Ultrabook.

The only issue you may have is with the TV. Not all TVs with HDMI ports read the signal from a computer. The converter gives the signal for TVs. I'm not sure about the output signal from the USB device. (If the port is labeled HDMI/DVI, it is more likely to support a computer's signal.) There are also VGA to component video or composite video converters that will do similar signal modifications. These don't have the HDMI issue. (Make sure you don't get a VGA to component cable; these are for projectors that can talk to computers.)

I hope this helps.

Computer has vga port and tv has hdmi port


Please know that VGA is an analog signal and HDMI is digital so it is impossible to go from one to the other without a converter. If you need to convert any VGA or component signal into a digital high definition HDMI signal up to 720p resolution, this conversion box will do the job perfectly. The only additional thing that you need to get besides this converter is an HDMI cable of the appropriate length.http://sewelldirect.com/Component-VGA-to-HDMI-Scaler-720p.asp Hope this Helps you!

What kind of wire do I need to connect my samsung laptop to panasonic viera hd 3d plasma tv?


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.

VGA has only analog video signal. It is not digital and does not have any audio either.
HDMI is a digital connection standard with both digital video and digital audio signals.
A cable with a VGA connector on one end and a HDMI connector on the other still needs a converter box to convert the analog signals into the digital signals required for the TV's HDMI. Click on the following link to go to web page titled VGA to HDMI Cable - An Unfortunate Myth

Hi hassy786,

Regarding your question if you will use a converter from VGA to HDMI will it provid High Defenition video?

I believe that it will provdie video converting the signal from VGA to an HDMI connection but I do not think that the video will be High Definition since the VGA is just being converted to HDMI signal and not an actual HDMI but just a converted signal, and it is possible that it may not work properly or the LCD TV may have difficulties recognizing the signal from VGA converted to HDMI.

Thanks for chosing Fixya,

LG W2361V 23 Vga to HDMI Cable Not Working


You have a cable problem as no such thing as a VGA to HDMI cable exists.

HDMI is a didital signal and is thus not compatable with an anolog VGA signal. HDMI to DVI cables however do exist as both are digital signals.

Hope this helps.

Can i connect a dvid cable from the monitor to my flat screen tv hdmi to watch videos from my computer? Thank you Martin


the Flat Screen TV if has, a HDMI input, also has VGA Input.

You must choose :HDMI or VGA, if HDMI The VGA board must Have HDMI Connector, and you connect a HDMI cable to the TV.

The HDMI is a digital signal input/output, VGA is Analog Signal. You must have Signal Converter if you Use the 2 signals

What do I need to hook it up to an hdtv...what type of cables..DVI-D to HDMI?


Your laptop will need a HDMI output or a DVI output for HD video. If your laptop only has a VGA out the your tv will need a VGA or DVI input. You could use a vga to dvi adapter if your tv does not have a vga connector. They do have a DVI to HDMI adapter but there are a couple of problems with that. One you will not get the sound and the TV will only obtain sound from HDMI cable when connected that way and Two the TV will have problems processing the signal from the computer due to the HDMI will only process the HD signals at certain formats and the computer video can send out many different signals. I tried and I could not get my tv to process the signal so I got a video card that has a HDMI out and my blu-ray player works great.

Is it possible to connect my computer with a VGA output to my HDTV with HDMI inputs?


hi there, sure it is.
either check if the video card has two output interfaces(VGA and HDMI) so use the white HDMI-otlet with a cable and your TV, else do get an VGA-to- HDMI adaptor and try connecting the VGA outlet and your TV-set.

Good luck
