Question about Televison & Video

This denotes a problem with the power supply either the low voltage power supply of the high voltage power supply. You will need the following documents and equipment if you plan on doing this yourself: 1) a schematic diagram 2) a Multimeter 3) an oscilloscope 4) a signal generator (color bar, cross hatch, and purity) The schematic will let you know where the test points are and the level of voltage and signal are supposed o be at the test point. The multimeter will allow you to trace and measure DC and AC voltages throughout the set. The oscilloscope will allow you to view the waveforms generated by the signal generator, this is needed to tell if a component is not processing the signal in the proper fashion. The signal generator creates a standard reference to measure by. Since this prolem is in the power supply section you should determine if the problem is a blown fuse by visually inspecting the fuse. Than you will need to determine if the problem is in the high voltage power supply. You do this by checking the transistors in the horizontal section of the TV. you will find the problem either in the low or high voltage power supplies.
