Try this HDMI input with other HDMI source such as DVD, Blueray or from cable box. If it does not work as well, you need to replace mainboard.

"Not Supported Mode" Message...


Your tv does NOT support any higher than 720p res.
Is your cable box set to this? If not, and it is set to 1080i than it would explain this, and is also a common problem with computer(vga) connections even with monitors. To see the current resolution the box is set to hook up a yellow jack to the to from cable box just to get the picture back long enough to navigate to a setup menu and lower the resolution back to the highest supported which is 720p

HDTV Cable box conflict


This set does not support 480I in the DTV mode, only 480P and 1080I is supported. Try setting the analog setting in the cable box to 480p and that should take care of watching the set in DTV. Most cable boxes have a setting for format changes in the customer menu, depending on the type of box. If you are able to change the format, then the other inputs will not work since they need a 480I signal, as well as VCRs. Another setup could be to use the S-Video cable or Video input jacks to get a better picture in 480I instead of using the cable input. However, when changing from HD to Analog, you will have to change to the correct input on the set as well. Hope this helps.
