All my hdmi ports on tv have stopped working !!

by sjfrytbg / July 26, 2011 7:36 PM PDT

I have a Samsung LE40B650 which is only 18 months old and about a week ago all the hdmi ports will no longer show any picture. If I unplug the hdmi lead it does show not connected so the port does see something. However no matter which device or cable I try I just get no signal. I have an xbox 360, blu ray dvd and a virgin hd box and none will work on any of the ports. I have tried a factory reset but this did nothing. Does anyone have any suggestions or have they experienced the same issue?

Try to reset the TV back to factory settings that may help by pressing the exit button for 20 sec's

I have already tried to reset back to factory default. managed to find the remote key combo to get into service mode and did it in there, but still not working.
Got a tv repair company coming this afternoon to give an estimate.

Just thought I`d share.. Tv guy came out to fix and apparently their are two chips on the main board which he has switched. All hdmi now working.
This cost me £58.00 which is better than paying the £125.00 fixed price fee for comet to come out?? Still not good considering the telly is only 18months old...

This just happened to my TV as well

I have a Samsung TV as well and the HDMI ports on it just stopped working. Bought it back in August of 2010 so less than 2 years and it's unusable. I did get the 3rd party warranty however, so I suppose that's good.

1. I can't tell if you tried the old reset noted at

2. The chip appears to have identifiers on it if you research the boards. You as the tech would hit for the manual, buy the manual and see if they have it listed. If not you pull the board and trace from the HDMI port to the first big chip and replace that chip.

There is no repair manual.

There could be a "Service Manual" as These run about 12 USD and are usually where we separate out the techs.

Holding Exit Button 20 Seconds Works!

I spent an hour talking to Verizon and the guy told me to buy regular cables as my HDMI didn't work any longer. I did the 20 seconds of Exit, reset to factory settings and now everything works great.

try waiting
by chase2013 / February 10, 2013 1:48 AM PST

My two HDMI ports stopped working on my Samsung TV at the same time. I hooked up component cables and watched that way. The next day I tried the HDMI again -- at first it didn't work but I unplugged and replugged and checked the tightness and they worked. (I only unplugged and replugged the one to my TV but then the one to my blu ray also worked when that one did). Someone told me they just needed to "rest".

Hi chase2013,

It's called the HDCP handshake. When it fails, it stops trying until a power cycle or a re-connection. That's why it seems so temperamental.

Thanks for sharing a tip. I turned off my tv for an hour or so and unplugged all HDMIs. Then powered on TV and all of the HDMIs ports are working fine.

All My HDMI Ports Stopped Reading Signals
by KMAC1535 / August 3, 2016 9:20 AM PDT
In reply to: It worked for me

Thanks to all for your posts and suggestions on fixing this issue. 3 days ago all 4 of my tv's HDMI ports suddenly stopped working. When I moved from (HDMI) source to source, all I could see on the tv screen was a message stating there was "No Signal". However, I knew the tv was not totally jacked up as the A/V connection worked.

I tried unplugging the tv (overnight) for a period of about 12 hours. That didn't work. Then, a few moments ago, I figured I would try another suggestion from the list. I unplugged all 4 HDMI ports and then unplugged the tv. I waited for about 5 minutes, plugged the tv in and then subsequently plugged the HDMI cables into the ports (chronologically….1, 2, 3 & 4). Presto! It worked.

I cannot say specifically if it was unplugging the HDMI ports or plugging them in chronologically (so the tv would identify them individually). But, it works.

Thanks and good luck for anyone experiencing this issue in the future.

Wow! A new angle.
by Postalbird / March 4, 2017 8:31 AM PST

Dido, dido, dido with the Samsung. Funny thing is my tv service provider works in all 4 HDMI inputs. Its my blue-ray and xbox that don't get acknowledged as being connected. My screen totally blacked out in the middle of ESO at the same place I was dc'd earlier from the zenimax server. I thought it was the xbox for hours until I was able to try another xbox and 3 new cables, and a blue-ray player they all read the same "This source is not connected. Please try the connection again."

Did that fix stay fixed? Mine just started doing it. I bought a new TCL and was going to return it and get another Samsung. But after reading all these posts I think I'll keep it and see how that works.

Waiting Game
by danad00dle / March 29, 2016 4:50 AM PDT
In reply to: try waiting

I also seen something about the whole waiting thing but what they suggested was unplugging everything and waiting like 10 minutes before plugging everything back in and starting first with the device, turning it on, then the tv, and supposedly it should help. Did not work for me (closest I got was sound with no picture or a picture for about two seconds), but it is recommended to do and repeat the steps for each port. Good luck!

Same issue here
by zzydrius / January 13, 2016 7:55 AM PST

My Samsung stopped connecting to HDMI back in 2013. Cable TV box was found bad and HDMI ports (all 4) stopped working. I used component video ports until now, nut now I need at least one HDMI. Hmm, I guess I need to find TV repair guy.
The story with cable boxes was long and interesting. Cable guy replaced 3 of them. Only 4th started to work. And now I think that it started to work when he connected component cable. Is it possible that Samsung TV burned cable TV receiver over the HDMI somehow?

Set top boxes surge.
by Q-Division / May 28, 2016 10:18 AM PDT

It is possible for "set top boxes" to surge. Newer sets have extra surge protection. Not yet sure if there is a fix for older equipment.

Temporary Fix and Useful Information
by danad00dle / March 29, 2016 4:43 AM PDT

I had encountered this same issue as well after a storm when my HDMI ports were blown and for the time being, until I figure out the issue with the ports I used an alternative cord to connect the cable box to my tv. I had to call to ask about all the cords you are able to use but here is a list:


I wanted to share this as my father in law almost went and bought a new tv and I at the least stopped him until I am able to fix the underlying issue with the tv itself.

On another note, one thing I did find while investigating was replacing the main board on your tv, I watched a youtube video in which you can order one from the site for your specific tv and looks relatively simple and not too expensive to do. Good luck everyone! Still troubleshooting as well.

All HDMI ports stop working.
by edrich32 / November 12, 2017 6:14 PM PST

This usually needs a main brd replacement,
to allow you to use your hdmi ports again.
What usually happens here is you were
struck by lightning unknowingly.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
