Monitor K7500 monitor & video bd -

K7500 is a 25‑inch Wells Gardner arcade monitor used in high‑resolution cabinet displays. Common failure modes include a defective flyback transformer (often indicated by black wire on the ferrite core), degraded electrolytic capacitors on the neck board, and IC failures such as Q800 or U500 chips that cause no picture or distorted video. First‑check steps: verify mains power to the chassis and confirm the monitor’s indicator LED; inspect the flyback for burn marks or loose connections; then test the neck board voltage rails and replace any electrolytic caps showing bulging or leakage before reflowing solder on common problem points.[oss-gpt-20b] Post Comment
