Servicing TV circuits with the ESR meters

摘要

Troubleshooting defective capacitors and electronic components in the low voltage power supply and scan-derived circuits of television sets can be made easier with the ESR meter. The ESR (equivalent series resistance) meter was designed to locate defective capacitors (1μF and up) in or out of the circuit. The ESR meter can locate a bad electrolytic when the regular capacitor tester will not. You can quickly check most electrolytic and bypass capacitors right in the power supply circuits in minutes. Besides a good or bad reading, the ESR meter sounds off when a good capacitor is located (Figure 1).
