Turning a TV (or monitor) into an oscilloscope?
This question comes up so often and it does sound like a neat project to give a defunct TV a second life. Don’t expect to end up with a Tek 465 on the cheap when you are done. However, it could be a fun learning experience. CAUTION: See the safety recommendations below. You will be severely limited in the performance of such a scope. TVs and monitors are designed to operate at a very narrow range of horizontal scan rates and the high voltage is usually derived from the horizontal deflection. So, you would need to retain the original deflection system for this purpose at least. • You will need to disconnect the deflection yoke from the horizontal and vertical deflection circuits of the TV or monitor without killing the HV. (also, doing all this without killing yourself as well). Depending on the design, this may be as simple as unplugging the yoke connector. More than likely, you will need to substitute a load for the horizontal deflection coil. A coil from another sacrificial similar T
