I had the same problem but by yesterday evening they were back...if need be just try some fine tuning ...my tp is 3880H30000. .n saw another 1 on 3872H29999. ...all the best lakini.Their tp weakened about a week or so and i even lost them. I went back to the dish and did some farther fine tuning and they are back. You may have to do the same if you had them before. All the best.
