Hello friends, I have a hantek 5102P oscilloscope with a few months of use and hours of use where it is not taking measurements. I already updated the software. Turns on normally, accepts all functions, updates without error, performs high calibration and nothing is inoperative. I performed the 5v1khz output test with no signal. I made the following measurements with an oscilloscope and noticed that the test that should have output 5v has less than 1votls. I noticed that the 78r05 board regulator on the board shows 0.95v. So I removed and did the test off the 5v regulation board. Some component on the board is killing it by lowering the regulator voltage. Has anyone had this defect or could help me I have a schematic
