I'll first analyze the power supply board, where I find a swollen capacitor and check the voltages produced by the switching circuitry dedicated to the control board. I'll then check the power supplies in the high-voltage section dedicated to the backlighting. During the video, I also restore the battery of a tablet that had dropped below the threshold. I continue the investigation by analyzing the control board and performing a thermal imaging scan, and finally, I use the hair dryer to identify the faulty component. ⏰ Index: 0:00 Prologue and Theme 0:53 Introduction 1:45 Audio-Video Anomaly 2:58 Power Supply Board Analysis 4:45 Supply Voltage Measurement 5:30 How to Resuscitate a Tablet Battery 7:05 Electrolytic Capacitor Replacement 9:00 Voltage Measurement on a Smoothing Electrolytic Capacitor 11:00 Test with Lamp Power Off 12:30 Test with Control Signals Off 13:40 Diode and MOSFET Test 15:30 Thermal Scanning with a Thermal Imaging Camera 17:00 Stress Testing with a Hair Dryer 18:50 Heatsink Tests 20:00 VGA Test #repairs #electronics #amplifiers #lab #tools #oscilloscopes #tutorials #projects #tv #audio #pieraisa #electronics #technicians
