Question about LG 47 47LW5600 47 3D LCD TV

No signal on HDMI ports?

Hello, Out of nowhere the HDMI ports appear to have stopped working on the TV. One of our cats stepped on a remote and BAM nothing worked. We can't seem to figure out what setting he might have changed, if any, or if that was just a coincidence sending the TV into a downhill spiral. We've tested our components and cables on another TV and they all work. Thanks

    Just to add....we've tried unplugging the TV overnight for a "reset" but it doesn't do that. I've reset it via the options menu in the TV though. The internet connection works as does the Component in1 plugs (a Wii is connected to that and it works fine).

Don't know what the cat could have done, but this is usally a problem with Satellite users after a near lightnig event. Does not have to be a direct hit to the receiver. Since you tried everthing with another TV ,Right? and it worked you will need a new main board for the TV if you wish to use HDMI

SOURCE: Remote not working anymore for my LG 42PQ20. Ive tried changing

call LG if you think the TV is not accepting the signal from the remote the TV may have a fault in it. If you have any universal remotes try programing them to control the TV if they work but the other does not it is remote.

SOURCE: "No signal" sign on TV screen using HDMI selector

it sounds like a refresh issue, double check you selector and make sure it fits the refresh of the tv. i had this once with a sharp where the tv was 120hz and the selector was 60 and it created a no signal and when it did come in it was jumpy. if you have a 120 tv then selector should be the same.

I may put money that some one did stole your internal cable from the power supply to the main board !

Don't be surprised they did it to me at LG company .

SOURCE: HDMI PORTS DONT WORK

Hello,

You will need to replace the main video logic board, its part number is either EBU60852909 or EBU60852911. These two board are direct replacement parts. There are several boards available on Ebay such as this one: http://www.ebay.com/itm/LG-46LD550-UB-Main-BPR-Total-Assembly-EBU60852909-subs-to-EBU60852911-/150895037335?pt=US_TV_Boards_Parts_Components&hash=item23220b8b97

SOURCE: LG TV HDMI no signal problem

You need to make sure the TV is set to the same input that you are plugging into. This is done in the video menu.

Sony KDL-40NX711 HDMI PORTS STOPPED WORKING. EVERYTHING ELSE WORKS FINE. WHAT WOULD CAUSE THIS TO HAPPEN?


Sounds like everything works. Your remote has an input menu. Have you cycled it around to the right component? i.e. HDMI1 or HDMI2, or DVD, even PC?
If not, try that.

T V turns on, can't get the HDMI to appear on the screen for the signal.


HDMI is the High Definition Media Interface PORT on the back of a modern Flat Panel TV or Monitor.
The remote control should allow a selection menu to appear on the screen so you can choose an alternate signal input from another device or set top box.
Perhaps the TV senses that there is no signal on that HDMI cable plugged into the back port, so therefore it won't show it on the screen menu.
Turn on the device attached to the other end of the HDMI cable.

46 inch Sony Bravia TV is 5 years old. HDMI ports 1,4 work fine but 2,3 don't.


I presume you've checked that the HDMI cables are good, and that the signal sources (e.g., blu-ray player, Roku, etc.) are working correctly. If the HDMI ports are individually selected by four buttons on your Sony remote, which is unlikely, it's possibly a problem in that remote. It's also possible that ports 2 and 3 are physically damaged by abuse. If you have ruled out all of those potential causes, this is almost certainly a problem in the way the defective ports are attached to the underlying printed circuit board inside the TV, or a flaw in that PCB. Too bad it's out of warranty. Repairing this will be a hassle if it can be done at all, and probably not cost effective. Instead, I suggest three possible workarounds for your consideration.

First, if you can find another way to get the signals into your TV, such as using the component inputs instead of HDMI, that will your cheapest and easiest alternative. This will only be doable if the signal source offers other types of outputs besides HDMI. Note that I am NOT suggesting adding any type of signal converter, just a different way of connecting the signal source to the TV.

A second alternative is to buy a multi-port HDMI switch with a remote control which you can find for less than $30 at online retailers like ebay. Plug that switch into one of your two good HDMI ports, and connect your unserved signal sources to the switch. It will be slightly less convenient to use the multi-port switch because you will need to operate one more remote control than you do now.

The third possible workaround is to buy an autosensing HDMI switch instead of the multi-port type, which would eliminate the need for the extra remote. However, an autosensing switch must have only one signal source active at any given time. This may not be possible if one of your signal sources is a streaming device that is continuously powered up. Good luck!

Too many connections here---likely a hookup issue if both sets work alone and frankly the wrong way to do this.

I continue to have to switch my HDMI cable between 2 ports on my TV because initally there is "no signal". But when I switch ports I get a signal. So is this a HDMI cable issue, port issue or my Insignia...


My best bet would be a port issue - see if another device will work plugged into that port. (Some HDTVs have a HDMI port strictly for Service and nothing else but a Technicians specified cable will work in this port, look at the Manual) Check to see if your TV is set to the same port as your connecting to. One will be HDMI 1, next HDMI 2 and so on, the input button on remote should switch from port to port, make sure port setting on TV is same as #port your connected to.

Hdmi port stopped working on sony bravia KDL-32L4000, when I connect my ps3 or direct tv trhough hdmi cables I will just get a blank screen that will say no signal.


I have a Sony Bravia model KDL-46s5100 that had the same problem. All HDMI ports stopped working. I don't know why this works but unplug the TV for about 30 sec, then plug it back in and hold down the power button on the tv for 10 seconds. Like I said I don't know why this works but it worked for me. Good luck.

RCA 46" LCD TV - HDMI Stopped working overnight


I don't mean to sound ignorant, but can I assume you have already checked your Source Selection just incase someone hit a different button on shutdown ?
Sometimes when I just set the remote down can sometimes change a setting on the TV, I thought maybe the same may have happened to you too.
