I had a Tascam 244 in the workshop with an issue where one side of the stereo image was dead, both when monitoring using the line out RCA socket son the rear of the unit and when using the headphone sockets at the front of the unit.
In the end it turned out that the unit had two separate issues with overlapping symptoms 1) dry joints on one side of the stereo amplifier and 2) a dead operational amplifier on the headphone output.... but before I could diagnose those problems I had to first establish that the fault did not lie with the master fader or other components in the stereo signal path, so this video also includes a demonstration of how to remove the back panel and meter PCB form a 244, and use of inexpensive op amp and component testers.
