Your idea should be correct I assumes. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic

This is a common problem on these sets. As the menu is fine, this is highly suggestive of an internal failure.you have a driver board failing if you would open the set and on the left side is the Y-sustain board there are two boards connected to the Y SUS board. The one on the top drives the top half of the picture and the one on the bottom drives the lower half of the picture open the ribbon cables make sure to clean it or Re solder if you see needed turn set on and test, sometimes cleaning this will fix problem sometimes re soldering will fix problem and last resort is, the board itself is bad.Unfortunately,you need to diagnose and inspect all the components before replacing any part.If you wish to repair it yourself, i could give you a link to buy the service manual and would upload a troubleshooting chart ( generic ) that would explain how you need to diagnose the fault when you open the TV.However, there is no quick fix. It has to be opened and tested and then diagnosed.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
