Hi @bd3616
Bit confused here.
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 from a cable box, 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

Hi @bd3616
What is the model number of the TV?
Assuming that the Roku is connected to a HDMI port on the TV, how are the "service provider's channels" connected to the TV e.g. WiFi/Ethernet cable connection from a router, cable box/stb/pvr connection to TV, etc?
If a "box" of some description, what is the make and model number of it?

@jayeff thank you for the reply. Sorry for leaving out some of those details. The model number for the TV is LN32C530F1F. I have a cable box through the service provider and it hooks up from there to the TV with an HDMI cable. The Roku also connects to the TV through a separate HDMI cable. I even tried switching the HDMI cables to see if the one for the Roku would fix the issue for the TV but sadly it didn't solve the problem.

@bd3616
What is the model number of the cable box?
Did you try switching between the TV's HDMI ports as well?
If the cable box has a Component video output option (red/blue/green video + red/white audio RCA type sockets) try connecting it appropriate cables example only) to the component video + audio input sockets on the TV.
To me its seem like there's a problem in the cable box (or signal input to the box from the service provider) and not in the TV.
Try a power refresh on the cable box and check if that resolves the problem i.e. switch off the cable box and then disconnect the power from the cable box. Wait 5 minutes and then reconnect the power and turn it on. Allow it to re-initialise and then check. You should be able to do this without needing to set it all up again as the box would have to be designed to cater for unexpected power outages etc.

@jayeff The model number for the cable box says Pace PX022ANM. Yes, I tried every combination I could think of for switching out the HDMI cables along with trying each port for each HDMI cable. I also turned off the power button located on top of the cable box and unplugged the power source, waited 10 minutes, reconnected it and still having the same issues from time to time.
I will note that at times it seems worse on some channels than others. Just within the past week or two I got a text from our provider saying some service was done so I was hoping it would fix the issue but unfortunately it didn't. Also if it helps, a few weeks ago I thought I noticed that when I began to slightly loosen the coax cable it seemed to worsen the same issue. But I've made sure everything is tightened, etc.

@bd3616 clarify this "began having glitching/pixel issues" a bit better. Glitching really don't mean much to me :-) All of this " a few weeks ago I thought I noticed that when I began to slightly loosen the coax cable it seemed to worsen the same issue." sounds like there might be an issue with either the main board or the connectors on the board. Have you tried to disconnect the cable box or the ROKU completely to see if it is one or the other that may cause interference?
