TH-42PX60U All output ports works but HDMI ports

HDCP 2.2 wasn't released until 2014. The LG 55G2 was released in 2012. There's no way to upgrade the TV, unless you replace it. Using a splitter probably wouldn't help. The device sending the HDCP check needs every part of the HDMI cable daisy-chain system to send back a "Yes I understand" message in 20ms.

Since a receiver isn't usually sending copy-protected video, this message is coming from one of the devices. Reset the resolution for that device to 1080p. Based on your description of the problem, you need to change the video output on the cable box. This depends on the cable box model and the guide it uses. However, either turn off the receiver with the cable box and TV left on. Alternatively, connect the cable box to the TV directly. For some, you then press Menu (for the cable box) twice to get to general settings. Then enter the audio/video section and look for the video output formats. See https://www.spectrum.net/support/tv/hdtv-picture-formats for some of the reset steps. In some cases, you may need to use a different video output to the TV to get a picture, instead of the error message, to access the menu at all.

On my set-top box, I sometimes connect the RF output to the RF on the TV when the set-top box sends a "out of range" signal. I set the TV to channel 3 (in my case) and then reset the video format. Other times, I just get the blank screen but the menu still works to reset the output format.

I hope this helps.

the cable may have trouble

Using a box of some kind? try unplugging that and wait then plug back to see if the issue is the box. It will try to reboot.

It will depend on your video output options on the computer. If you have HDMI output, just use an HDMI cable and an audio cable (this will need to be a 3.5 mm to RCA audio cable). If you have a DVI output, use a DVI to HDMI cable and the audio cable (or a DVI to HDMI adapter and either a DVI or HDMI cable depending on which side you want to put the adapter). If you only have VGA out from the computer, use a VGA to DVI adapter and the DVI to HDMI connection and the audio connection. (Theoretically this should work but each adapter will have some signal loss issues.)

Some graphics cards have a video output, S-video or Component video, which would also connect to your TV with the audio cable. (Read your cards manual for more information)

I hope this helps.

(For DVI to HDMI cables, you will need to check if you have a single link or dual link DVI output. The wrong cable may not work.)

Here sounds like your override setting on cable box needs to be set.
Here is how to fix that-
1. On remote push the button at the top that says CBL or Cable.
2. On remote push power button.
3. On the remote push the menu button.
This should bring up an internal menu called user settings.
4 Use the remote to scroll down to 4:3 OVERRIDE and use the LEFT or RIGHT arrow keys on the remote to change the value to 480i and see if this clears up your problem. If not repeat and change the setting to 480p and one of these settings should fix your problem.

Good Luck and please rate this solution.

your HDMI output is bad

POSSBLE ' DG ' BOARD IS BAD NOT CHEAP!!!!!!!!!!!!!

are you using a PC to feed a signal or maybe a cable with an adapter?
I had the same issue when I used one of the rear HDMI ports to show a PC display. Apparently there is a software difference between the rear and side/front ports. Inputting the PC through the side HDMI port has solved the problem for me (so far!)

On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.

Please unplug TV from AC outlet and replug it after 5 minutes then check HDMI port.
