Replacement Level Supported

The replacement level supported for this product is to the printed circuit board (PCB) and major
subassembly level. Once you isolate a suspected PCB, follow the procedures in the Repair and
Disassembly section, to replace the PCB with a known good PCB. Check to see if the symptom
disappears and that the monitor passes all performance tests. If the symptom persists, swap back the
replacement PCB with the suspected malfunctioning PCB (the original PCB that was installed when
you started troubleshooting) and continue troubleshooting as directed in this section.
