TV won't recognize laptop when connected via HDMI ...

First, make sure your TV is on the appropriate input for the plugged in HDMI cable. Once this is completed, turn your ps3 on. If the screen comes on and is black, turn the ps3 to standby (red light is on) and hold the front power button until the console beeps a second time. This will usually force the ps3 to recognize the hdmi input and will bring up the menu to configure the AV settings.

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.

What kind of receiver? Do you have anything else like DVD player going thru receiver? My receiver has 3 hdmi in and 1 out (to tv) so all those equipment would just go to "hdmi" on tv.
Another way to do it is put your tv on exterior audio... for all sound to go thru your receiver.

Your resolution on your ps3 may be too high for the tv to display. Hook up your PS3 to you TV with the HDMI cable. Now, when you turn on your PS3, hold the power button on the PS3 for 5 seconds. It will reset the PS3 video options and recognize the HDMI connection. It will then search for the correct resolution settings on the TV. Press (X) to confirm. And that's it. You should be set. If not, then the TV is acting rather strange.

Sounds like your blue ray player is defective

The Roku is the problem, not the TV. You need to go to the Roku site and request download information to synch the Roku to an HDMI input.

Try another HDMI cable. I have seen them become defective. If it is not the cable, then try another HDMI device to test the TV.
Without an HDMI cable tester, and a way to measure the output of the HDMI source device the only way to resolve this is with the process of elimination.

power off your pc completely and remove hdmi cable. with the tv on, plug the hdmi cable back into your pc and power it up. tv should be recognized.

go into the video setup menu, and select HDMI set up and select "ON" that should do it
