Any help would be appricated

you will have to recheck all of your work very carefully. Magnifing glass in hand, I use a jewelers loop. look for solder bridges, objects that should not be there, leads that have been missed durring soldering, correct components in the correct places. Many times I have found that soldering flux will cause malfunctions, so I clean the board with alcohol and a tooth brush. That will get problem areas that can be missed with a visual inspection. Then I use 409 and tooth brush to remove any sticky flux residue followed by a rinse and then a trip to the XYL's hair dryer. I would put a drop of rtv on any adjustments so water will not get inside of pots. There is one very difficult problem area and that is when you have a solder bridge. Did you remove all of the solder? are you sure? some times the solder will still be bridged underneath the chips where you cannot see it.
