my megger 1710 multifunction tester. This was in perfect working condition up untill last week when it developed a fault which wont allow any tests. It just shows err75 and sometimes on the loop test it shows err50. It also shows as if there is high voltage as you can see from one of the pics. I have tried everyting from fuses to different leads and batteries but still doesnt work. I opened it up which caused a couple of marks on the top as you can see in the pic to see if there was anything obvious inside that was broke. It may just be something simple i do not know. I just got it out of the box and went to check in a socket
