My machine is on, but, the only thing showing on the screen is the HP symbol and a line that keeps going back and forth which makes me think it is warming up. This happened before and the machine eventually powered up on its on. (It's been warming up for 5 days.)

I had this same problem and spend hours working on it. Took the side panels apart to get a better look. Nothing anyone said fixed the issue. Not even the link everyone keeps posting to HP's carriage jam fix. Was out of solutions and about to give up and order a new printer. There was one last thing I had to try that I didn't think was going to work, but I had a theory. Right after I tested this solution it started working again. This worked for me, but anyone who has tried every and have not got their printer to work can try it.
My Solution: Open the front covers and look inside. Just above the metal rail that the carriage travels on there is a thin plastic strip about 1/4 in. width and should have a glossy shine to it. I believe this is some kind of positioner. It runs through the carriage and gives it some kind of position. After years of use, it'll become dirty with ink. I used some tissue and alcohol and wiped the strip clean. It worked perfectly fine right after. Below is a picture of the strip I underlined with a yellow line.
