You said previously "...I've temporarily unplugged both the cable box and Roku but the issues continue like normal." which I understood to mean that the TV kept glitching, although I don't know what signal source was connected to the TV so that you could see this happening.
Then you said "So you want me to disconnect the HDMI cords that are connected to the TV that come from the cable box and Roku? I hadn't done that before no. I just tried it now and fiddled around with some menu selection screen but I don't see the issue being there at all when I did that." which I understood to mean that there was no glitching when viewing the menus.
Could you please describe the setup there e.g. cable box > HDMI > TV or cable box > coax > TV? Which is it you're using to watch TV channels?
If you've tried using either then is it glitching on both connection types?
Assuming you tried cable box > HDMI > TV this means that the box is in close proximity to the TV is this correct?
If so then if you get suitable length AV cables (examples linked above) and then see if cable box > AV > TV causes any glitches.
''If not'' it could be the TV as both the HDMI and coax use digital signalling which means that the DSP (digital signalling processor) on the main board is being used, whereas AV is analogue and the TV doesn't need to use it. The menu screens are also analogue direct from the mainboard. Although in saying that since the Roku is also using digital signalling this indicates that it is not the TV.
If there are glitches when using cable box > AV > TV then it could be the cable box or the signal being sent from the service provider.

Hi @bd3616
You need to determine where the glitching problem is coming from.
-
The TV has 3 signal sources connected to it. A coax input, a HDMI input from a cable box and a Roku HDMI input (is the Roku connected to the cable box or router by WiFi? It must get its signal from somewhere if using it for internet app streaming etc?)

So it could be either the TV or one of the signal sources.
To narrow it down do the following:
Disconnect all signal inputs from the TV and then connect the ''coax input only'' to the TV and check if the glitching occurs. Allow sufficient time to ensure you know whether it still is happening or not. Then is it Yes or No?
Next disconnect the coax input and connect the ''HDMI input from the cable box only'' to the TV and check if the glitching occurs. Allow sufficient time to ensure you know whether it still is happening or not. Then is it Yes or No?
Next disconnect the HDMI from the cable box input and connect the ''Roku HDMI input only'' to the TV and check if the glitching occurs. Allow sufficient time to ensure you know whether it still is happening or not. Then is it Yes or No?
Depending on the results:
If glitching occurs on all 3 input types then most likely it's the TV.
If glitching only occurs on the inputs from the cable box i.e. coax and HDMI or only 1 input from the cable box then it could be the cable box or the TV. Have you checked that the firmware installed in the cable box is the latest version? Check the user manual for the cable box and also the cable TV provider's website for details. With a lot a cable providers they automatically update the cable box firmware but not all of them do.
If glitching only occurs on the Roku HDMI input, then it may be the Roku device or whatever signal source it is connected to.
Once it is known what signal inputs are connected when glitching occurs then you can start to find out what to do next to try and resolve the problem
