I've had my new G-Hanz HD TV. 42" 3D. it was working fine with my receiver using Av1. recently I got IOMEGA multimedia with 1T Hard disk. I tried to connect it to the TV using both HDMI ports I have but still saying no signal. I changed the cables 3 times and still no signal. It works for 5 or 10 minutes and then say no signal. even I ex-changed my TV as it was new (got it 7 days ago) and the same problem appear. It works with AV (composite cables) but I need HDMI to work for 3D movies. the thing now the the AV1 that was working is not working now any more and the second AV (AV2) the only one working now. I am really getting mad. anyone can help!!! Thank u in advanced.
