I have a Sony Wega DLP with no sound through HDMI all of a sudden. Can't give exact model at the moment but it is a projection TV definitely 5years old at least. It has only 1 HDMI input and I've been using a splitter box to run my DirecTV and Xbox through the HDMI input. Worked great for years then recently there's no sound. Picture works fine and sound works through component inputs. Any ideas? Do I need to replace the HDMI input or something?

I have a Hitachi 42PD7200 plasma tv. The hdmi port works with the new xbox 360, satellite tv and until recently my Samsung bluray player. When the bluray is connected (via a 4 port HDMI switcher of directly to the TV) it shows the bluray starting up with the Samsung logo and then gives the message invalid frequency. At this point the picture and normally sound are lost. I have connected the bluray to another TV using HDMI, the same cables and it works fine. Has anyone come across this problem

I have an LG 37LE5500 TV. That's plugged into a DSTV Satellite HD PVR Decoder via HDMI. The TV is new. Before I had an old CRT TV and was using the AV (Red/White/Yellow) cables. The LG LED TV has been working fine, except that I've started to notice a "clicking" / "static" sound coming from the speakers now, when using the HDMI connection. When I mute the volume, the sound goes away, so it's definitely not an electrical problem as far as I can see. Anyway, it only starts the "clicking" after

I am trying to set up my Xbox 360 to my dav c700 and I have everything plugged in and the surround ound works (well) although no video is showing on my screen. I cant work out where to plug the yellow cable in now...


First off you should switch to a high definition cord. But the yellow one will work for you. Just simply plug it into the yellow cable on the back, then switch to that input, the two sound inputs (white and red) will be next to this yellow input. ... Flat Panel Televisions

I have a Mitsubishi WD-73737 and when I turn on the tv the power light flashes very fast for a minute then stays a steady green and the screen is a solid blue. There is no sound as well. I have tried the system reset and it didn't do anything. I was given this tv, so I don't know how old it is. The tv will occasionally work but that is very random. The only item I have plugged in is an Xbox 360 with the component cables. The menu button does work so I know the screen still works.
