Did you touch up the solder joints? Hopefully it's something that simple ... or a connector that needs to be reseated?

Bad caps in vertical section.You can find out which ones using a hair dryer and chill spray.

deffenitly sounds like bad connections on the vertical pins. Resolder them even if they look ok. if that doesn't help look for faulty caps around verticle circuit. Try heating them with a hair dryier and then freeze spray.
