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...

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.

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.

Light bulbs you shouldn't buy

There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
