Hi, I got this #Tektronix #LogicAnalyzer #TLA5201, which sometimes turns on and sometimes does not (no boot sound at all). I removed and checked almost all the caps on the main board. Has anyone else encountered a #problem like this? As a last resort, I'm planning to put up a #postcard and check it out. Any help is appreciated.
Sorry for late response. It was actually powering up but not beep sound with black screen.
I replaced power supply, ram, HDD. Now it is working. Power supply voltages was little low so first I replace that. While testing I removed HDD and see If it boots. It was better but after putting HDD, after several boots it did happen again. I checked the power supply voltages when HDD was powered, 12V,5V rails looked somewhat low. Then I replaced HDD with SSD. I upgraded ram but not sure if it's related
@MrGreensWorkshop dry joints in the power switch / control side of things?
