What is the best way to replace defective equipment
I am currently having several issues with my Comcast Equipment (listed below). What is the best way to get replacement equipment? Is there a way to request it online or do I need to go into a store?
My issues are as follows:
1) My main box fan is very loud and runs all the time. We also frequently get pixelation on the TV screen. The box is a XG1-P Model Number PX013ANM. This box is connected to a 4k TV. How can I get an XG1v4 as a replacement?
2) I have a dead XiD-P, it will not work at all, needs replacing.
3) Over the past year, I have upgraded all TVs to 4k TVs and I can no longer pair any of the remotes to these newer TVs (I've tried the on-screen programming and dozens of codes I've found online - nothing will work). Also, none of my current boxes support 4k. How do I get boxes and remotes that will work with my newer TVs?
