I am having a problem , I have a Hitachi 50VS69A LCD projection TV with a HD Starchoice receiver , HD channels are fine but sometimes on regular channels , the screen goes black and says NO SYNC NO SIGNAL , sound is still on. Starchoice does'nt think its the receiver and Hitachi does'nt think its the TV............when you turn to a HD channel all is well and when you go back to the regular channel picture and sound are fine ..................it has no pattern...................seems to happen randomly..........signal strength is fine...........Starchoice is hooked up through DVI to HDMI cable.............Hitachi says cable is defective...................HELP PLEASE

Reset the box, unplug and let sit for 30secs.

Do the same with TV.

If that dont fix it, ask for a firmware update from Hitachi, the HDMI isnt communicating correctly.
