We've had our Hitachi 42" plasma for almost two years and it's worked great. But a few weeks ago, it stopped displaying over-the-air HDTV channels. It seems to think it's still displaying them--it shows the channel numbers when you flip through them via the remote, and it shows SD channels (and DVDs work/display fine). I checked the signal strength in the TV Menu -- all channels are 95% or higher strength. I got a new HD antenna, no change. I reset to factory settings, had the TV rescan for channels, etc. Obviously the display is working, but somehow it's not displaying the TV signals that it is receiving. Any suggestions?
thx
Dave
Try hard reset, Please unplug the tv cables and power cables for 30 min and redo the cable and check its working ....
Good luck...
