Vertical line appearing on Pro Monitor display
22 years old. Gear and prices may have changed since.
What the thread found
- A bright vertical line on a monitor display indicates a failure in the horizontal scanning circuit, causing the image to compress into a single vertical line the width of the electron beam.
- Prolonged operation with this condition can permanently damage the phosphor coating at the affected location due to concentrated beam intensity.
- The issue may result from a loose or disconnected wire in the horizontal deflection coil assembly.
- Before disassembly, connectors should be checked and wiggled with the power switched off, allowing time for the high voltage to discharge.
Depends on
- Discussion concerns an older monitor model from 2004.
- Advice assumes familiarity with high-voltage electronics components.
- No detailed repair procedure or parts replacement was provided in the thread.
- Resolution of the specific case was not described.
