Xbox Hdmi Adapter Why Won't My HDMI Adapter Work For My Xbox 360?

Why won't My HDMI adapter work for my xbox 360? - xbox hdmi adapter

I have bought recently, the HDMI adapter for my Xbox 360, because he is a former model and has no HDMI port. So I went to my 720p Insignia 32 "LCD TV, get in touch and the first he came to normal, but every few seconds would be a short circuit and the display would be black and white blur (eg if the cable is turned off the TV and that's black and white screen, like a bunch of ants on the other), and for a moment, then rise back to normal, then again on the screen, normal, etc., and perhaps would be stable only black go - have white screen. I tried the troubleshooting in the manual, but does not work. So I thought it was the HDMI cable, although it works on my TV cable box. So I have another, remains the same. I tried it on my father on television, but his 41-inch LCD TV 720p and it worked very well. So what happens KNW i dont. I kept my friends from the elite and use the HDMI connection and this worked well works. So my question is simply what's new? This is meNot only my tv, when the HDMI interface of the elite has worked well, it's fair that my singing TV HDMI support, but others may tv? Does anyone have any suggestions or answers? Thanks for any help.
