Hi folks, I'm new here and hope I'm posting at the right place. Looking for any help with my WD65838. Performing fine until a few days ago - my PC stopped displaying video. PC has worked fine through the tv for 3 - 4 years without problem. The pc connection is DVI out to HDMI 3 in on the tv. Originally in HDMI 3, I tried HDMI 1 and 2 - no help. Connected the pc to a desktop monitor - dvi to dvi, using the original cable minus the hdmi convertor - normal display, so I'm getting output from the pc. The only other hdmi source I have is another laptop. Connected hdmi to hdmi - no display on hdmi 1,2, or 3. Tried different resolutions - no help. Updated to latest version on the Mitsubishi site - no help. Reset tv - no help. Other sources are a dvr and a dvd connected to analog 1 and 2 inputs, and antenna - those are fine. I name whichever input I test to PC so it's looking for the right signal. Bottom line seems that my hdmi/pc inputs aren't working even though the tv "sees" the connection as soon as it's made. Am I missing a tweek somewhere? Again, apologies if I'm posting in the wrong place...this isn't really a reply about lamps.
