Horizontal compression and black bars appearing on a 4-inch CRT master monitor

ما توصّل إليه النقاش
- A CRT master monitor showing horizontal image compression with black bars on both sides may indicate a failing high-voltage power supply
- Horizontal deflection circuit problems, particularly the deflection transistor, can cause this type of display compression
- LCD monitors do not experience horizontal deflection issues because they lack the deflection circuitry and high-voltage components found in CRT displays
يعتمد على
- The issue was intermittent at first and then became persistent, but no resolution was documented in the thread
- The advice was specific to a 4-inch CRT master monitor model and may not apply to other display types
- No actual repair was completed or confirmed in the discussion
