Checking the test points with voltage meter yeah, Didn't get a reading on the main point (really only on battery port) but was mention to check loose wires till do i believe. One of the cables mentioned was to check the video cable, ln checking it out .it looks like it goes up through neck to back of screen., Guess could see why could be issue, maybe possible binded up issue somehow or tension in some other location causing something to come loose, guess could see that. maybe could see it coming loose. So i was wondering for folks that remember working on these in the past, ever come across loose wires? In dealing with that test, find any? Btw, missed out on same machine today, guy had one listed $20 and worked good a town away but it was just sold.
