The manual provides guidance on using the Sencore HA325 Horizontal Output & Flyback Analyzer to test the horizontal output stages and integrated high voltage transformer (IHVT) of Mitsubishi projection TVs without applying AC power to the chassis. It includes instructions for setting up the HA325 for testing, connecting it to the TV, and interpreting test readings to identify defects in the horizontal output stages and IHVT.
Manual Overview
The Sencore HA325 Horizontal Output & Flyback Analyzer is designed to diagnose defects in the horizontal output stages of Mitsubishi projection TVs, particularly the V18 chassis, without requiring AC power. The manual outlines the process for using the HA325 to conduct the Horiz. Output Load Test and the Flyback & IHVT Load Test. The Horiz. Output Load Test simulates the horizontal output stage’s operation at a reduced power level, allowing for safe analysis. Proper setup involves connecting the test leads to specific points on the chassis and adjusting the DCV input to approximately 9.3 VDC, with a test frequency of about 33 kHz. Normal readings for a functioning V18 chassis are around 53 mA, 58% efficiency, and a pulse width of 4.2 μS. The manual provides detailed instructions on connecting the analyzer and interpreting the test results to identify defects in the horizontal output and high voltage stages, ensuring accurate diagnostics and effective troubleshooting at the board level.
