Hello and sorry you're having problems. I may be able to help, but I need to ask for more info. Can you please get me the model number off of the back of the TV?

Thanks for the reply. This is a 3 CRT rear projection TV, and what causes the picture to roll like this is the Horizontal/Vertical circuits- which are a common cause of failure in this set. It's not usually something that is easily corrected, except for in the case of cold solder joints (which is possible since vibration seems to cause the problem). To have this repaired at a shop is typically a $250-$350 repair and you can locate one at the link below if you'd like: www.tvrepairpros.com If you need further assistance let me know.

Since this may be a simple cold solder repair and my husband is extremely handy can you tell me what it looks like and where it is located in the set - hoping we can do this ourselves.

Unfortunately this set is extremely complex, and I would not be able to describe where to locate the possible bad solder joints. For a DIY repair I would suggest purchasing the Service Manual for the set, and referencing the Vertical/Horizontal circuits and related components in the Block Diagrams: http://www.tvrepairkits.com/xcart/hitachi-50ux22b-service-manual-and-schematics.-convergence-repair-kit.-instructions-and-parts-for-diy-tv-repair..html If you need further assistance let me know.
