Unplug the TV for a while and hopefully, that should reset the circuity. If you're using the original remote control, check for the display button and press it.
I would also suggest doing a factory reset if your TV has that feature and if the TV allows you to do it after unplugging it.
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.

Try the command code switch. I recently had a similar problem when my remote suddenly stopped working. It worked fine one time but nothing the next time I tried it.
I checked the emitter with a digital camera and found it was not working. I did the remote reset (remove batteries and push all the buttons twice, reinsert batteries) and the emitter was now working. However, the remote would still not control the base unit. I did the remote base code reset (push power, volume and TV/DVD buttons together) but this did not help. I then checked the command code switch. This is a small three position slide switch located in the battery compartment on the remote. I slid the switch back and forth several times returning to the default number one setting where it was before. I did not change anything on the base unit but the remote now worked.
I am guessing that your DVD player could be broken and the laser part that reads the disc's is also not working too and the disc drive is also broken. The disc drive and everything that is attached to the disc drive needs to be replaced all together.
It could be that the board inside of the remote where the buttons are attached to are dirty and need to be cleaned with qutips and rubbing alcohol or there is a problem with it's infared sensor on the remote or on the TV it's self or pairing problems or if the remote was damaged then. In those cases I would buy another remote for your TV.
last man on earth on tape?
buy 2 machines used and now have parts( NO OTHER WAY!!!)
there is no books AT SONY or support now. it ended long ago\ 1987 ,35 long years ago/.
the free shop manual is here, 155pages
I would try and unplug the TV and all of the attachments that are connected to your TV and wait for a few minutes to plug everything back in again and see if that fixes the problem. It could be an issue with your TV's mainboard or a power supply issue.
Make sure the MUTE function has not been activated. Try turning up the volume level. Check that there are no headphones connected. Check if the issue also occurs to other device connected to the TV.

5 red flashes is a bad panel connection or internal panel short, very carefully take the panel connectors off and reseat them and see if that helps, unfortunately you may have a bad panel.
The front and back pieces are like a clam shell and are compression fit with tabs into one another. You need to use something like a guitar pick or spudger to separate the pieces. Dont use metal objects due to damage that will happen to the plastic .
Probable damage to the main board caused by lightening/storm activity.
It is possibly not ever going to be a successful repair.
Being LCD it is older technology and spares will be few and far between, not to mention expensive.
I can assist you with that problem the LED blinking is actually indicating a specific error based on the number of blinks.Let me know how many blinks in between pauses.
There is a manual for this model available in pdf format unless you have the original instruction book. Page 23 outlines 'command mode' where you can try pressing ENTER and the corresponding number buttons simultaneously on the remote for more than 3 seconds while pointing RC at the recorder. In your case, because your recorder is set to command mode 1 - press ENTER and 1 together on the remote. This should allow you back into the on-screen menu to revert the command mode back to 3 (which is the default) and it should work. The online pdf manual for this model: http://www.docs.sony.com/release/RDRVX560_EN_ES.pdf unless you still have the original. Pages 22-24 show some of the setup procedures. The pdf is not very big so you can save it for future use if needed.
