Rolling horizontal black bar 1" tall on the tv screen
There is a horizontal rolling black bar about 1" tall that seems to go from bottom to top on the tv screen. resetting the tv seems to help for a while, but the problem reoccurs after about a minute. with the dvd on and all other inputs shut off, the problem is still there.

It is not possible to diagnose it without a hands on investigation. It could be ICs; I am not doubting that, but it must be determined by an actual investigation. Check out the Integrated Circuit (IC) Capacitor and Transistor on both on CRT board.

If your TV looks 3D, warped, or distorted it likely has a convergenge problem. If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured. You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com
This TV needs a service adjustment done. Looks like a vertical or horizontal IC is failing. I'd go ahead, and shut off until services adjustment is made. Have you unplugged for a few minutes and plugged back in? However, I'd have a service tech look at it.
Initially, sounds like a capacitor at the vertical section about to fail, leaking or blistered. Additionally, have seen some of these models suffers from vertical fault due to a defective capacitor in the power supply section or cold solder.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
horizontal lines = horizontal sync off . mitsbishi always seemed to have this problem .. on the older sets I would take the back off and inside deep on the board i would adjust a pot and sync it right .... and never had a recall, maybe your newer model has this too .. this little control,
Hi, your vertical section is beginning to fail, from your description you have a few electrolytic capacitors that are beginning to go bad, the correct term is they are "leaky", the set can be fixed easily by a tech, not so easy for a layperson because you don`t have the service manual or a capacitor analyzer. NOT an expensive fix, tech will have to remove board, unsolder some caps, check them and replace the bad ones, do a little touch up solder work and set is good as new, any questions? feel free to ask away, if not Happy Holidays, BMW Rider
