I recently received the "main board has been changed. please go into service mode and setup below options. -type, local set, front color option." Does anyone happen to have this model tv and can let me know what the settings are supposed to be. I haven't changed the main board which is why this is so bizarre. Anything that I plug into the HDMI inputs just blinks. No video, just audio. The "type" in the service menu says "none," so I know that these must have changed. Thank you advance!
