"No Signal" from HDMI ports, UN50M5300

Bought this TV last summer, set it up as a "smart tv" and it worked fine. Decided to add Comcast cable and xbox to it after the holidays, so the Comcast guy came over w/a new box - no signal. Tried different cables, etc., no luck. Tried new Xbox One, no signal. Swapped out cables, reset TV (several times), no signal.

Plugged Xbox 360 into component, and that worked, but no signal thru HDMI. 

 

Tried live chat, they reset TV, but still no signal thru HDMI ports. USB, ethernet, wifi, and component all work.

Any ideas? 

TIA

Do the HDMI ports seem loose when you connect an HDMI cable to it? Have you tried asking for a replacement box with Comcast to see if that is the root of the symptom?

HDMI ports seem fine - no wiggles, if that's what you mean.

I've swapped other cable boxes from around the house and the Xbox - all with different cables as well, no luck.

The red "power" graphic shows up next to HDMI on the "source" menu, but no signal...

 

very frustrating

Turns out the main board was bad. Under warranty, so tech came to the house. Whole repair, including signing paperwork,  took less than 10 minutes...

Here (Samsung). PM'd w/TV info, turned out to be warranty work. Took the tech less time to swap out main boards than it took to dismount/mount TV...

I believe so. Swapped out and all has been fine since. Don't know if it came that way or failed early on, but the fix has worked for a year now.

im having the same issues with my tv. I happen to have a samsung plasma, i know kinda outdated but it seems like the overheating of the main board caused the hdmi to have no signal tho the port is a bit wiggly from the pulling of the wire as time progressed. at first i thought it was a problem with the cable box until i looked at a few videos showing what may have caused this issue and thats when i noticed how hot the main board got when i turned the tv back off and unplugged it during my own troubleshoot attempt lol.
