Re-flowed solder connections, now no display

Tech Square

Technical and speculative discussion of amps, cables and other topics.

I have a Sony (probably mid 90's) big screen projection TV. I've been losing the red at the bottom quarter of the screen for several months and discovered several cold solder joints, on the circuit board that has all the video alignment pots. I re-flowed the solder connections and now I have no display on the screen at all!
(I don't have schematics)
I took photos of the card before disconnecting, so I'm 99% sure I have everything hooked back up correctly. I'm also sure I didn't overheat any components while soldering.
This is NOT making sense to me. Anyone ever work on these TVs before?
Thanks in advance for any help, Brian.
