 The most common cause of frustration is jumping to (wrong) conclusions. You hear it or see it, make a snap decision of the problem and then focus all your attention on that assumption. As Hippysmack points out, you need to detach yourself from what you think, or believe so strongly in, so you can strictly focus on what you can prove.\\ The most common cause of frustration is jumping to (wrong) conclusions.

 We generally suggest doing certain tests because we have found the results to be important indicators of where to look for the source of the problems. Often times, the original poster (with the problem) doesn'​t understand why we're asking a certain question or when given a list, simply overlooks EACH and EVERY test check suggested. But, in most cases, EACH and EVERY test was intended to produce usable information toward a solution. We generally suggest doing certain tests because we have found the results to be important indicators of where to look for the source of the problems.

-Long-distance diagnostics requires lots of accurate and specific information so that 'WE SEE' what you seeand maybe see what you don't see. And that is where having a video (or pics) of 'the problem'​ can be evaluated & assessed for help from afar. The perception may be the same as you had, but it might also be perceived quite differently because of other'​s experiences and knowledge, even though they are remotely located, trying to assess what is actually happening and why.+Take one test and follow it thru to completion - AND ACCURATELY REPORT THE RESULTS so others know the facts. Jumping around between different tests, intermixing the test results in your report or only doing part of a test can all create more confusion and prevent getting to a solution.
