Windows 7: HDMI to TV no longer working

HDMI to TV no longer working

I have been using my flat screen TV to view movies on. I haven't had a problem with until now. All i get is an error condition saying no signal present. I tried another working hdmi cable but still get the same error condition. I ran a complete scan on the computer but everything passed. I have a Dell Inspiron 570 running a ATI 4200 with an up to date driver. A technician told me that the component that the cable plugs into in the back of my computer is probably bad which i either watch my movies on my computer screen or get a new computer which I really can't afford. Does anyone have any ideas. I have a Samsung TV which i have no problem with and i have switched the plugs around but still the same thing.

Have you switched the HDMI cables around with the power on? If so, don't do that. You can easily blow an HDMI port that way.

It may be that if you plugged or unplugged the HDMI cable with the power on to the TV or to the computer, you may have damaged the HDMI port in either the TV or the computer.

Test the HDMI inputs on the tv with another device, a blu-ray player etc.

If it works fine then..... by all means please buy a new video card.

Go Green a 950 is very inexpensive.
