Model: Hantarex MTC-9110

Symptom: Partial vertical foldover. R117 on the remote board was burnt.

Diagnosis: Monitor was working before being shipped in the game. Chassis wasn't bolted down and had slid around. Replacing R117 with a higher wattage (all I had on hand) did not help and it still got very hot. Checked vertical output IC and found no problems. Traced back through chassis and found cold solder joint on pincushion board transistor. Touched up various suspicious solder joints throughout chassis. Monitor now works fine. Bolted chassis to frame.

Solution: Repair cold solder joints. Replace R117.
