Member: 977479 Status: Offline Sonork: 100.1638508 Thanks Meter: 795 | As I show in image. Check with multimeter on beep. If multimeter give some value then that key is in working condition, check each key one by one like this. If during this process, any key gives beep sound, it means that key is short. then check the track of that key properly........ |
