TST tire pressure sensor failure.

I have a TST 507 SE tire pressure sensor system that became very erratic and eventually stop displaying temperature and pressure all together. I would be embarrassed to admit just how much time I spent programming and reprogramming trying to solve this problem. It's uncharacteristic of me to depend on tech support but out of desperation I gave them a call. The rep, Jim, was a very knowledgeable and helped me troubleshoot the problem. One thing he mentioned was a possible loose antenna. Although the antenna did not seem to be loose I opened up the case and inspected the antenna connection only to find the pad on the circuit board where the antenna connected had been torn loose and disconnected. Looking back, I recall the holder suction Cup losing grip several times resulting in the display falling to the floor. This no doubt was the cause for the broken antenna solder pad. With magnifiers, a bright light, a steady hand and solder gun I was able to solder a tiny jumper from the antenna post to an adjoining via on the circuit board. Problem solved. As I always say, almost anything is worth repairing once.
