Slow motion, clear on left side darker black haze in middle and blurred on right. after warming up it clears but comes back. hard slap to right side seems to fix for that viewing period

The panel or TCON board has failed, the solution is the same replace the panel. Not worth the cost, get a new TV

SOURCE: Sony KDL-46XBR4 much darker on the right side of screen

Hi Ron, thanks for describe many valuable details. You suspect something wrong with the fluorescent tube, if it is true, shall be dark on top or bottom, not left or right, also the problem with the backlight the TV will shut off and the timer LED will blink 6 times.
I think there is the bad connection inside the panel or the t-con board, only think you can do is try to reconnect the wires under the aluminum foil (see the picture) or replace the panel.

if the line is pixel thin, it could be a bad lcd panel. if it is a wider bar, it may be in the video circuitry. many of these sony tvs had bad panels, and sony has extended the warranty. call up sony with your model and serial # and date of purchase and try to get them to help you out, that is your best course of action. let me know if you need more troubleshooting assitance.
