Thanks for all the background, super detailed! I had a similar problem on a new Samsung that was really flaky with my HDMI from a raspberry pi. Would have to do all kinds of unplugging, cycling power etc like you're doing to get it to work. Once on it would work until I turned the tv off (actually doesn't turn off, but goes to sleep) and back on. Finally figured out that the resolution I was outputting wasn't supported, BUT sometimes it would work. Once I changed the resolution to a supported resolution it worked all the time.
i would try go to - graphic properties(options) and try to browse for display options, if nothing's there than browse for update for your graphic card drivers on laptop producer website or hdmi drivers
Make sure you have a good hdmi cable, and make sure you have a signal. Try another HDMI slot, and see if that helps. If nothing works, unplug the HDMI inputs and turn the set off overnight. Then plug each HDMI plug in one at at time, and turn the device on. This helped in a couple of instances I know of.
Since I don't know the model you have, the following blog may or may not be helpful to you: http://forums.logitech.com/t5/Harmony-Remotes/JVC-TV-input-problem/td-p/241569
Good luck, and hope this helps.
Hi gregschirk, I bought the same model and I am experiencing a similar problem. My HDMI components worked fine before. Now both my cable box and DVD player will not be recognized as HDMI systems. It thinks they are DVI to HDMI connections. Good picture but no sound. Would like to know if there is a fix for this. Thanks Gilbo72
Hi, This model has 4 HDMI inputs, do you get same problem in each HDMI input? Did you checked HDMI input with any other video source like dvd player or PS3 etc instead of cable box? Below are few helpful tips to connect HDMI input.. 1. Ensure that your HDMI cable is certified. 2. Press SOURCE on the remote control to switch to another source and then switch back to the HDMI source. 3. Reset the accessory device and the TV. • Turn on the TV • Select the HDMI channel • Turn on the accessory device 4. While the TV and the accessory device are powered on, unplug either end of the HDMI cable and then reinsert the cable. Try above options and if tv still does not show picture of any video source through HDMI then it seems problem of HDMI processor located on main board, visual check is needed by qualified tech or call Philips if tv is under warranty. Hope these info will help you. Thanks.
