HA325 Horizontal Output & Flyback Tester
Overview
The HA325 provides exclusive analyzing tests of horizontal output stages, flyback/IHVT transformers, inductors, and switching transformers to localize horizontal circuit defects faster than conventional methods. Its exclusive Load Tests and Ringer Tests isolate defects that previously required many hours of expensive troubleshooting or component swapping.
The HA325 provides a “chassis off” Load Test of the horizontal output stage to determine if the stage is free of severe defects or if problems exist. The Load Test simulates the operation of the horizontal output stage at or near 1/10 of its normal level and analyzes the resulting current and voltages. The Horizontal Output Load Test is valuable in determining if defects are in the horizontal output stage or the main power supply and/or if circuit problems caused the horizontal output transistor to fail. It's also helpful in isolating horizontal defects that would cause component damage or high voltage shutdown if AC power were applied to the display.
The HA325 provides a test of integrated high voltage transformers (IHVTs) or flyback transformers to determine if primary to secondary shorts, loading/efficiency defects or integrated multiplier section defects exist. The Flyback & IHVT Load Test establishes a test circuit in which the flyback or IHVT is placed into a tuned horizontal output stage at either a TV or high scan frequency. In a manner similar to the Horizontal Output Load Test, a setup is established and the currents and voltages analyzed to identify flyback or IHVT defects.
Features
Improves the skill of your service technicians for faster more profitable repairs. Find the horizontal output transistor or IHVT, hook up the leads and the HA325 automatically makes the analysis Reduces second (and third) visits to the home on field calls and reworks - The HA325 helps you troubleshoot the horizontal output circuits confidence and locate the problem on the first try. Cuts down on replacement repair costs - Replacing parts that aren't bad can be a massive drain on service center profits. The HA325 helps you quickly and accurately determine defective parts in the horizontal output circuits. Increases the accuracy of your estimates - Some of the most expensive parts in a video display are in the horizontal output circuits. With one simple hookup the HA325 quickly identifies what is working and what isn't. Specifications
