Is that how you found it? One wire is missing!!!! The solder splatter and mess can be cleaned up with a Q tip and isopropyl, but the burns will remain. As long as the burn isn't between any two traces, the board is usable. If you are not experienced with soldering, the turntable should be returned to the seller, or ship it to a technician. Even some techs are poor at soldering. Sorry to convey the negatives, but much better to know in advance, and ask about the tech's soldering skills, and send photos if possible. Shipping the turntable presents another great challenge, as it is a heavy but fragile item. They often arrive seriously damaged. The arm resistance near the rest position is not a worn bearing problem, but it could be a damaged bearing race from previous disassembly. Another cause as mentioned here by other members, can be a malfunctioning anti-skate mechanism, or tone arm wire in contact/ hung up on a mechanical part. There is also the possibility of a botched attempt to service the turntable, and a part may be out of position, a cycle (arm return) pawl out of position that interferes with free movement of the arm. The SL-1200 is one of the most reliable turntables ever built, very sorry you are having these problems.
