I have a JVC projection TV model # nv55bh6. Recently it started having wavy lines go from the top to the bottom like a vertical hold but the picture does not roll, just the lines. I know, I know. It's a 10 year old TV but we are not ready to kick dirt on it just yet. Being a tinkerer I opened it up and noticed that one of the crts is making a humming sound. Could this be the problem? And if so is this something I can fix on my own? I have a short video of the problem on my phone I can send.
