OK,  so remote fell... Simply stopped working. Followed a YouTube vid and touch the joints.  Great worked for 10 minutes then stopped.  Touched up joints again never work, checked the ir sensor with a camera, it's light is continuously on. Checked if any bridged joint, nope. Where should I look next? Also as the Pic shows, from the + terminal to 1 ir point (continuity)  from the - terminal to both ir points (continuity).. Normal???

Simple repair for you guys but I'm a beginner, will appreciate any help!
